Increased genetic sequencing of African A/H1N1 pandemic influenza viruses during 2009-2013 revealed multiyear persistence of 2 viral lineages within West Africa, raising questions about the roles of reduced air traffic and the asynchrony of seasonal influenza epidemics among West African countries in the evolution of independent lineages. To elucidate the evolution of influenza viruses in Africa, we conducted a large-scale phylogenetic analysis of global pH1N1 influenza virus diversity during 2009-2013, including 299 pH1N1 HA sequences collected in 18 African countries.

In the current study, we examined a series of samples of different tissues, collected at autopsy, for the presence of HBoV and PARV4 DNA sequences and compared the frequencies of detection, viral loads, and genetic variability with those for B19. Samples from HIV-infected individuals who did not have AIDS (hereafter referred to as "pre-AIDS study subjects") and those with terminal AIDS at time of death were compared with corresponding samples from HIV-uninfected individuals, to investigate the relationship between viral load and immunosuppression and, thus, the role of the immune system in controlling virus replication.

In this study, we used an experimental approach designed to maximally detect antigen-specific CD4 + T cells by using cytokine enzyme-linked immunosorbent spot (ELISPOT) assays with pools of overlapping synthetic peptides as recall antigens to quantify responses to conserved and novel epitopes following vaccination of adults with monovalent inactivated A (H1N1)pdm09 vaccine. We conclude from this that expansion of CD4 + T cells rather than the baseline number of influenza virus-reactive cells correlates with and predicts the development of a neutralizing antibody response following A (H1N1)pdm09 vaccination, a result that is consistent with the idea that CD4 + T-cell help may limit the antibody response to pandemic influenza vaccines. cache = ./cache/cord-000842-kff3gig0.txt txt = ./txt/cord-000842-kff3gig0.txt === reduce.pl bib === id = cord-267458-uofy7jyx author = Jiang, Xiao-Lin title = Transmission potential of asymptomatic and paucisymptomatic SARS-CoV-2 infections: a three-family cluster study in China date = 2020-04-22 pages = extension = .txt mime = text/plain words = 1622 sentences = 124 flesch = 59 summary = title: Transmission potential of asymptomatic and paucisymptomatic SARS-CoV-2 infections: a three-family cluster study in China We report a three-family cluster of infections involving asymptomatic and paucisymptomatic transmission.

Respiratory viruses are detected as etiological agents in almost one third of cases of community-acquired pneumonia (CAP) [2] [3] [4] [5] and in 7%-36% of patients with severe CAP with a defined microbial etiology [2, 3] . We aimed to investigate the prevalence, risks, and prognostic factors associated with pure viral sepsis in adult patients with CAP, using the Third International Consensus Definitions for Sepsis and Septic Shock (Sepsis-3) criteria [6] .

In other systems, archived sample banks have helped identify Middle East respiratory syndrome coronavirus-seropositive camels in East Africa over 11-year (Kenya) and 30-year (Sudan and Somalia) periods, suggesting extensive virus circulation in camels prior to the first human outbreaks [35] [36] [37] [38] .

The results of the present communication demonstrate, on the basis of the excretion of typical oocysts in the feces and the attachment of typical stages of the organism to the brush borders of enterocytes, that these artificially reared red deer were infected with Cryptosporidium, There is thus strong circumstantial evidence to incriminate Cryptosporidium as the cause of diarrhea and mortality in the outbreak.

V. cholerae group 0: 1 was rarely identified for children less than two years of age but was an important pathogen in older children and adults, while non-group 0: 1 vibrios were found in the stools of 4010-11 010 of the patients of each age group for both years of the study.

However, EBOV-GP 2014 was less susceptible than EBOV-GP 1976 to blockade by a third inhibitor, CatL ( Figure 3B ), which inhibits catB and catL activity to similar extents [40] , suggesting subtle differences in the protease dependence of these GPs. HIV-derived particles rapidly lose infectivity when stored at room temperature [41] , and this loss might be due to inactivation of the viral envelope protein. Comparably Inhibited by IFITM Proteins and Neutralizing Antibody KZ52 IFITM proteins 1, 2, and 3 inhibit cellular entry of EBOV [42] and several other viral pathogens [42, 43] and might reduce EBOV amplification in the infected host, raising the question of whether viruses circulating in 2014 are less susceptible to IFITM protein inhibition than those responsible for the 1976 outbreak in Zaire. cache = ./cache/cord-001764-njzyu4mv.txt txt = ./txt/cord-001764-njzyu4mv.txt === reduce.pl bib === === reduce.pl bib === === reduce.pl bib === === reduce.pl bib === id = cord-007180-pho3miid author = Heine, J. title = Enteric Lesions and Diarrhea in Gnotobiotic Calves Monoinfected with Cryptosporidium Species date = 1984-11-17 pages = extension = .txt mime = text/plain words = 3396 sentences = 216 flesch = 47 summary = Clinically affected calves have atrophy of villi and hyperplasia of crypt epithelium (apparently as a result of the destruction of villous epithelium); those areas of the small intestine that are heavily infected with the parasite become inflamed [7, 9, 10] .

Because 1 patient had both the L386del variant and the wild-type variant in the same specimen, they raised the possibility that SARS-CoV exists as a quasi species, at least in some patients. Previous authors studying single-nucleotide variants from Beijing-area isolates in 2003 [2] and from the Singapore 2004 outbreak [3] have also found multiple viral sequences in the same sample that they attributed to quasi species. Although these 3 studies clearly establish the presence of a diversity of SARS-CoV genomes in individual patients, the issue of whether SARS-CoV quasi species exists remains open, particularly with respect to the 386-nt deletion.

[6] A similar outcome, "vaccine associated enhanced respiratory disease (VAERD)," was observed in infants, 4 -12 months of age, who were given formalininactivated respiratory syncytial virus (RSV) and a few months later infected by RSV. The biological behavior of some coronaviruses in non-human species together with evidence that human coronavirus antibodies enhanced infection of SARS or MERS CoVs in Fc receptor-bearing cells, in vitro, have led to speculations that ADE contributes to disease severity in humans. [11] It has been reported that high levels of SARS CoV-1 IgG antibodies circulated in severe SARS cases and that anti-S IgG neutralizing antibody (NAb) responses developed significantly faster after the onset of clinical symptoms in fatal compared with recovered cases leading some to attribute enhanced tissue damage to ADE. With others, we conclude that the differences in clinical, epidemiological and pathological features of SARS and DENV diseases suggest that iADE does not contribute to the severity of natural human coronavirus infections. cache = ./cache/cord-278260-3o91v72a.txt txt = ./txt/cord-278260-3o91v72a.txt === reduce.pl bib === === reduce.pl bib === id = cord-286596-p10t0dta author = Erard, Veronique title = Airflow Decline after Myeloablative Allogeneic Hematopoietic Cell Transplantation: The Role of Community Respiratory Viruses date = 2006-06-15 pages = extension = .txt mime = text/plain words = 3383 sentences = 164 flesch = 39 summary = We conducted a 12-year retrospective study to determine the effects that the community respiratory-virus species and the localization of respiratory-tract virus infection have on severe airflow decline, a serious and fatal complication occurring after hematopoietic cell transplantation (HCT).

Rather, in light of pandemic circumstances-similar features of which may be replicated in other contexts, including research conducted in low-and middle-income countries or with participants whose nonresearch options are limited even in the absence of a pandemic-offers of compensation may raise ethical concerns akin to incentives [14] .

The possible use of insect cell-displayed S protein for diagnostic application was assessed by examining fragment reactivity with serum samples from patients infected with human CoV 229E and also with serum from a patient with suspected but clinically unconfirmed SARS (serum sample 3118). Of the 2 assay formats we used, nondenatured S protein present on the cell surface provided the most sensitive detection of antibodies, with clear shifts in fluorescence for serum samples from patients with suspected but clinically unconfirmed SARS. cache = ./cache/cord-261472-qcu73sdu.txt txt = ./txt/cord-261472-qcu73sdu.txt === reduce.pl bib === id = cord-299149-lc2dxvxz author = Chen, I-Cheng Mark title = Evidence for Cross-Protection Against Subsequent Febrile Respiratory Illness Episodes From Prior Infections by Different Viruses Among Singapore Military Recruits 2009–2014 date = 2019-06-15 pages = extension = .txt mime = text/plain words = 4265 sentences = 192 flesch = 42 summary = ResPlex II assays and real-time polymerase chain reaction assays were used to detect viral pathogens in nasal wash samples, and survival analyses were performed to determine whether infection with particular viruses conferred short-lived relative cross-protection against FRI.

Because the widely used antihypertensive medications angiotensin-converting enzyme inhibitors (ACEi) and angiotensin II receptor blockers (ARB) may upregulate ACE2 receptors [7] [8] [9] , through which severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) enters the host cells [10] , concerns have been raised as to whether their use may result in increased morbidity and mortality [4, [11] [12] [13] .

The findings that seropositivity occurs in small numbers of poultry workers exposed during outbreaks of illness in poultry caused by some avian strains (H7N7, H7N3, and H5N1) but not others (H7N1 and H5N2) argue for actual infection and support the notion that some avian influenza viruses are more likely than others to infect humans [1] .

The frequency of the mannose-binding lectin-2 codon 54 allele was significantly different among the 3 types of responders, with a decreased odds ratio for the development of poor or adverse responses (P = .033). The present study explored the possibility that host gene polymorphisms influence inactivated influenza vaccineinduced immune responses by comparing the frequencies of 8 SNPs in the MBL-2 gene and in the TNF-a and IL-10 promoter regions among different groups. We found a significant difference in allele frequency in the MBL-2 codon 54 among the poor, normal, and adverse responders, suggesting that the allele polymorphism is independently associated with poor and adverse responses to influenza vaccination. These findings support the present data by suggesting that the Ϫ1082 allele polymorphism in the IL-10 promoter region may be associated with adverse responses induced by influenza vaccine. cache = ./cache/cord-007375-hqmyund4.txt txt = ./txt/cord-007375-hqmyund4.txt === reduce.pl bib === id = cord-268490-e8jub01m author = Moscona, Anne title = CSI Microbiology: Emerging Pathogens and a Staged Strategy for Detection and Discovery date = 2007-12-15 pages = extension = .txt mime = text/plain words = 1069 sentences = 54 flesch = 39 summary = [2] in this issue of the Journal makes 2 unique contributions to this field: it demonstrates the need to consider and identify rhinoviruses as a cause of serious acute respiratory disease in children, and it establishes the MassTag polymerase-chainreaction (PCR) multiplex platform as a practical tool for microbial surveillance.

Current scientific knowledge is insufficient to manage the risks of severe disease or death of volunteers in SARS-CoV-2 human challenge studies, especially in terms of selecting low risk volunteers [2] . It is not obvious that the possible benefits of developing a successful vaccine in less time justify the risks SARS-CoV-2 challenge studies, as Eyal and colleagues suggest.

The half-lives estimated from the mean decay constants across all relative humidity levels without simulated sunlight present were 55 and 86 minutes for aerosols generated from virus suspended in culture medium and simulated saliva, respectively. cache = ./cache/cord-332303-0bbw64p5.txt txt = ./txt/cord-332303-0bbw64p5.txt === reduce.pl bib === id = cord-321006-rxuq3ux8 author = Chang, Luan-Yin title = Lack of Association between Infection with a Novel Human Coronavirus (HCoV), HCoV-NH, and Kawasaki Disease in Taiwan date = 2006-01-15 pages = extension = .txt mime = text/plain words = 2332 sentences = 107 flesch = 53 summary = title: Lack of Association between Infection with a Novel Human Coronavirus (HCoV), HCoV-NH, and Kawasaki Disease in Taiwan We investigated whether infection with a novel human coronavirus (HCoV), called "New Haven coronavirus" (HCoV-NH)—which is similar to and likely represents the same species as another novel HCoV, HCoV-NL63—is associated with Kawasaki disease (KD) in Taiwan. The evidence that suggests that the etiology of KD can be traced to an infectious agent includes temporal clustering and marked seasonality, geographic clustering, a strong association between the frequency of KD and infectious-disease surveillance [2, 9] , and age distribution (with the highest incidence among children 6 months to 2 years old, who have little maternal antibody and are, in general, the most susceptible to infection) [2] . An aliquot (2.6 mL) of RNA isolated from the clinical specimens, the positive template (10, 100, 1000, and 10,000 copies of the in vitro-transcribed RNA), and the negative control (distilled water) were subjected to real-time RT-PCR. cache = ./cache/cord-321006-rxuq3ux8.txt txt = ./txt/cord-321006-rxuq3ux8.txt === reduce.pl bib === id = cord-324701-7vjdlt1v author = Dahlmann, Franziska title = Analysis of Ebola Virus Entry Into Macrophages date = 2015-10-01 pages = extension = .txt mime = text/plain words = 5322 sentences = 273 flesch = 49 summary = Lectins, TAM receptor tyrosine kinases (Tyro3, Axl, Mer), T cell immunoglobulin and mucin domain (TIM) proteins, integrins, and Niemann-Pick C1 (NPC1) have been reported to promote entry of ebolaviruses into certain cellular systems. Here, we show that mannose-specific lectins, TIM-1 and Axl augment entry into certain cell lines but do not contribute to Ebola virus (EBOV)-glycoprotein (GP)–driven transduction of macrophages. To confirm and extend these observations, we compared the ability of lectins, TIM proteins, and the TAM family member Axl to augment EBOV-GP-driven entry into 293T cells, which can be efficiently transfected and are highly susceptible to transduction mediated by ebolavirus GPs [11] . Quantitative RT-PCR revealed that less Axl and TIM-1 mRNA is produced in MDMs compared with susceptible cell lines, and siRNA-knock-down showed that expression of these factors is dispensable for GP-driven entry into MDMs. In contrast, Mer but not Axl expression was required for efficient GPdriven transduction and EBOV infection of MDMs. Similarly, Mer but not Axl or Tyro3 was found to be essential for efficient phagocytosis of apoptotic cells by macrophages [46] , indicating that Mer is the TAM receptor kinase active in macrophages. cache = ./cache/cord-324701-7vjdlt1v.txt txt = ./txt/cord-324701-7vjdlt1v.txt === reduce.pl bib === id = cord-327501-8s6dvanf author = Schwaiger, Julia title = No SARS-CoV-2 Neutralization by Intravenous Immunoglobulins Produced From Plasma Collected Before the 2020 Pandemic date = 2020-09-17 pages = extension = .txt mime = text/plain words = 2367 sentences = 124 flesch = 52 summary = Testing 54 intravenous immunoglobulin preparations, produced from plasma collected in Europe and the United States, confirmed highly potent neutralization of a seasonal coronavirus; however, no cross-neutralization of the new SARS-CoV-2 was seen.

We first used the inhibitors of RLR and CLR signaling pathway to evaluate their potential contribution for mediating the proinflammatory response in MERS-CoV-infected macrophages. To assess the contribution of RLR or CLR pathway to induce proinflammatory response, we measured the expression levels of a series of key proinflammatory cytokines and/or chemokines in MERS-CoV-infected MDMs in the presence of these inhibitors ( Figure 1B ). Overall, the above results suggested that RLR and CLR signaling might be involved in viral recognition and trigger the proinflammatory response upon MERS-CoV infection in macrophages.

Both sequence entropy and genetic distances during the hepatitis E acute phase were higher in patients whose infection became chronic than in those who cleared the virus. We therefore analysed the characteristics of HEV quasispecies at the acute phase of hepatitis E in 2 groups of SOT patients, one whose infection became chronic and the other who cleared the virus. Both the complexity and diversity of the PPR and the macro domain were higher in viral population of the patients whose infection became chronic than in those who cleared the virus. cache = ./cache/cord-321132-xdpb3ukt.txt txt = ./txt/cord-321132-xdpb3ukt.txt === reduce.pl bib === id = cord-332175-d5suvj8g author = Allen, Jawara title = My Future in Medicine: How COVID-19 Is Inspiring the Next Generation of Infectious Disease Specialists date = 2020-04-11 pages = extension = .txt mime = text/plain words = 1246 sentences = 70 flesch = 59 summary = Three weeks later-on the day I was scheduled to start the clinical portion of my medical training-there were 418 700 confirmed cases of COVID-19 globally [1] . By that time, many courses had started remote instruction, most research laboratories had been closed to all nonessential personnel, and medical school core clerkships had been temporarily canceled, all in an effort to decrease student exposure to COVID-19 and help "flatten the curve. But as a medical student eager to reenter the world of clinical care, the personal stories from the communities that would be most impacted by this relentless pathogen soon consumed my thoughts. Few other events before have so poignantly highlighted the global nature of health, the vulnerability of certain populations around the world, and the need for more infectious disease specialists. But the importance of infectious disease specialists will not end once the number of newly diagnosed COVID-19 cases starts to decrease.

Using an indirect immunofluorescence assay and parallel acute and convalescent serum samples obtained from patients with SARS, tested for IgG antibody to SARS CoV, Peiris et al. In addition, our results indicated that 9 (25.0%) of 36 patients with probable SARS CoV infection had not produced detectable anti-SARS CoV antibody by day 21 after the onset of fever; this implies that 25.0% of patients with SARS might be misdiagnosed by the laboratory confirmation guidelines that WHO currently recommends [5] . cache = ./cache/cord-350737-nrtrhq1f.txt txt = ./txt/cord-350737-nrtrhq1f.txt === reduce.pl bib === id = cord-321580-3ru92tra author = Hadler, James L title = Will SARS-CoV-2 prevention efforts affect the coming influenza season in the United States and northern hemisphere? date = 2020-09-07 pages = extension = .txt mime = text/plain words = 1134 sentences = 71 flesch = 51 summary = The initial country-level responses to SARS-CoV-2 have provided substantial evidence of their collective impact on the COVID-19 pandemic and, incidentally, on seasonal influenza epidemics.

To know what might happen with influenza this coming fall and winter, we need to know what has happened prospectively in southern hemisphere countries, especially those that like the US have used fewer NPI's and used them with less rigor and, correspondingly, been less successful in controlling SARS-CoV-2 transmission.

Nasal foam swab self-sampling at home provides a precise, mechanistic readout of respiratory virus shedding and local immune responses. Here we demonstrate that home self-sampling with nasal foam swabs is well-tolerated and provides reliable results for monitoring viral load and molecular immune responses to respiratory virus infection. We have previously demonstrated increased sensitivity of self-collected foam nasal swabs compared to nasal washes in immunocompetent adults with respiratory viral infections [21] , and in longitudinal studies in solid organ transplant recipients [22] , with good compliance and participants reporting no issues with swab discomfort. M a n u s c r i p t In summary, we establish a foam swab-based sampling method that is optimal for patient selftesting, both at home and in the clinical setting, permits serial therapeutic monitoring, and is suitable for tracking the natural virologic and immunologic course of respiratory virus infections. cache = ./cache/cord-330645-46qaljq1.txt txt = ./txt/cord-330645-46qaljq1.txt === reduce.pl bib === id = cord-350749-ihkxouz8 author = Panda, Aditya K title = Plasmodium falciparum Infection May Protect a Population from Severe Acute Respiratory Syndrome Coronavirus 2 Infection date = 2020-07-29 pages = extension = .txt mime = text/plain words = 747 sentences = 51 flesch = 39 summary = title: Plasmodium falciparum Infection May Protect a Population from Severe Acute Respiratory Syndrome Coronavirus 2 Infection The authors have suggested that prior exposure of children to coronavirus OC43 offers protection against severe COVID-19 phenotype by possible crossimmunity. These observations encouraged us to investigate the possible role of Plasmodium infection on coronavirus disease 2019 (COVID-19) infection or severity. Based on these observations on Plasmodium infection and positive-strand RNA viruses, we hypothesized that there could be a possible association between malaria and SARS-CoV-2 infection. To validate our observation, we investigated the prevalence of COVID-19 in the Plasmodium falciparum-endemic area of Odisha, India, Odisha is highly endemic for P. falciparum for the last 10 years (2010-2019) from the National Vector Borne Disease Control Program and COVID-19 infection status in Odisha from the government of Odisha website (see https://health.

The absence of a reliable preclinical animal model that recapitulates patients with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection poses a major limitation to the development of improved diagnostics and therapeutics. Studies reported that SARS-CoV-2 developed no severe clinical signs, but pulmonary pneumonia in 50% of cynomolgus macaques, recapitulating mild symptoms in humans [6] . The viral RNA was highest in the upper respiratory swab samples and lung tissues at the earliest phase of infection, and the viral antigen was present in the lungs ( Figure 1C and D) , suggesting the predominant site of the virus. Using a high viral titre administered through combined routes, virus assays, and histopathological changes suggests that both cynomolgus and rhesus macaques are permissive to infection of SARS-CoV-2 and recapitulate COVID-19-like disease in human. cache = ./cache/cord-345101-h0i5o0do.txt txt = ./txt/cord-345101-h0i5o0do.txt === reduce.pl bib === id = cord-351776-otx5qwyu author = Ibáñez-Samaniego, Luis title = Elevation of Liver Fibrosis Index FIB-4 Is Associated With Poor Clinical Outcomes in Patients With COVID-19 date = 2020-06-21 pages = extension = .txt mime = text/plain words = 3896 sentences = 189 flesch = 44 summary = In this study, we evaluated the association between FIB-4, a liver fibrosis index, and the risk of progression to critical illness in middle-aged patients with COVID-19. To overcome this problem, we analyzed our data in different ways: (1) we retrieved available information on blood test done within 6 months before COVID-19 diagnosis in a relatively small number of patients (15% of the total series): at the time of COVID-19 diagnosis, AST and ALT increased significantly while platelets remained stable as compared with previous values; however, there were no significant changes in FIB-4 categories; (2) we evaluated specifically the prognostic value of isolated baseline AST: in contrast to previous reports, AST was not an independent predictor either at univariate level or when adjusted by other clinical and laboratory covariates; and (3) finally, we evaluated specifically the association between the elevation of AST (ie, AST above the upper limit of normality) and the need for MV, which identified that AST elevation was an independent risk factor. cache = ./cache/cord-351776-otx5qwyu.txt txt = ./txt/cord-351776-otx5qwyu.txt === reduce.pl bib === id = cord-352526-t8odetzw author = Pinto, Bruna G G title = ACE2 Expression is Increased in the Lungs of Patients with Comorbidities Associated with Severe COVID-19 date = 2020-06-11 pages = extension = .txt mime = text/plain words = 3032 sentences = 199 flesch = 50 summary = Although angiotensin-converting enzyme 2 (ACE2) is crucial for SARS-CoV2 to bind and enter host cells, no study has systematically assessed the ACE2 expression in the lungs of patients with these diseases. Here, we analyzed over 700 lung transcriptome samples of patients with comorbidities associated with severe COVID-19 and found that ACE2 was highly expressed in these patients, compared to control individuals. Correlation and network analyses revealed many potential regulators of ACE2 in the human lung, including genes related to histone modifications, such as HAT1, HDAC2, and KDM5B. The molecular mechanism responsible for the increased disease severity in patients with these comorbidities is not fully understood, but previous studies suggest a role for angiotensin-converting enzyme 2 (ACE2) (5) . Here, we showed that the expression of the gene encoding the ACE2 receptor in lung tissue is upregulated by diseases representing comorbidities along with COVID-19. cache = ./cache/cord-352526-t8odetzw.txt txt = ./txt/cord-352526-t8odetzw.txt === reduce.pl bib === id = cord-353495-c3s5n5vo author = Yao, Yanfeng title = An Animal Model of MERS Produced by Infection of Rhesus Macaques With MERS Coronavirus date = 2014-01-15 pages = extension = .txt mime = text/plain words = 3427 sentences = 186 flesch = 51 summary = In 2012, a novel coronavirus (CoV) associated with severe respiratory disease, Middle East respiratory syndrome (MERS-CoV; previously known as human coronavirus–Erasmus Medical Center or hCoV-EMC), emerged in the Arabian Peninsula. The infected monkeys showed clinical signs of disease, virus replication, histological lesions, and neutralizing antibody production, indicating that this monkey model is suitable for studies of MERS-CoV infection. The development of animal models for MERS-CoV infection of humans is of utmost importance to study the pathogenesis of this virus and to test the efficacy of potential therapeutic or prophylactic intervention strategies. Therefore, in the present study, we explored the suitability of the rhesus monkey as an animal model for MERS-CoV isolate human coronavirus-Erasmus Medical Center (hCoV-EMC) infection or disease. Rhesus macaques can be infected by MERS-CoV in the laboratory, but we recognize that it is necessary to search for more suitable animal model that will have similar disease presentations as that observed among those laboratoryconfirmed human cases. cache = ./cache/cord-353495-c3s5n5vo.txt txt = ./txt/cord-353495-c3s5n5vo.txt === reduce.pl bib === id = cord-352433-sts48u9i author = Galanti, Marta title = Direct Observation of Repeated Infections With Endemic Coronaviruses date = 2020-07-07 pages = extension = .txt mime = text/plain words = 3824 sentences = 170 flesch = 41 summary = BACKGROUND: Although the mechanisms of adaptive immunity to pandemic severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are still unknown, the immune response to the widespread endemic coronaviruses HKU1, 229E, NL63, and OC43 provide a useful reference for understanding repeat infection risk. CONCLUSIONS: This study provides evidence that reinfections with the same endemic coronavirus are not atypical in a time window shorter than 1 year and that the genetic basis of innate immune response may be a greater determinant of infection severity than immune memory acquired after a previous infection. However, in Korea, as reported by the Korean Centers for Disease Control and Prevention, viable SARS-CoV-2 was not isolated in cell culture of respiratory samples from potentially reinfected individuals [5] ; thus, these subsequent positive results may have been due to inactive genetic material detected by molecular testing. cache = ./cache/cord-352433-sts48u9i.txt txt = ./txt/cord-352433-sts48u9i.txt === reduce.pl bib === id = cord-350201-tluc2ck7 author = Kuiken, Thijs title = Zoonotic Infection With Pigeon Paramyxovirus Type 1 Linked to Fatal Pneumonia date = 2018-10-01 pages = extension = .txt mime = text/plain words = 3636 sentences = 209 flesch = 42 summary = The impetus for the current study was the identification of a virus related to avian paramyxovirus type 1 (APMV-1) from a fatal human case of unknown cause in the Netherlands by viral metagenomics analysis [8] . In this study, we fully characterized the Dutch clinical isolate of APMV-1-like virus, determined its phylogenetic relationship to other APMV-1 strains, and correlated presence of this virus with lesions in tissues obtained from the patient at autopsy. Domestic pigeons were inoculated intratracheally with the Dutch clinical virus isolate to determine infectivity and transmissibility, clinical signs, and pathological changes (Supplementary Methods). This is consistent with the New York case, where evidence of PPMV-1 infection in feces and urine also suggested extrarespiratory Pigeon Paramyxovirus-Linked Pneumonia • JID 2018:218 (1 October) • 1041 Table 1 spread [11] . It is relevant for these PPMV-1 cases that the risk of 2 pigeon-associated diseases-chlamydiosis and cryptococcosis-was largely a function of the immune status of patients, rather than contact with infected birds [32, 33] . cache = ./cache/cord-350201-tluc2ck7.txt txt = ./txt/cord-350201-tluc2ck7.txt === reduce.pl bib === id = cord-351571-gwtkrt5u author = Mackay, Ian M. title = Community-Wide, Contemporaneous Circulation of a Broad Spectrum of Human Rhinoviruses in Healthy Australian Preschool-Aged Children During a 12-Month Period date = 2013-05-01 pages = extension = .txt mime = text/plain words = 3374 sentences = 160 flesch = 43 summary = Human rhinovirus (HRV) infections trigger exacerbations of asthma and chronic obstructive pulmonary disease and the majority of acute respiratory illnesses (ARIs), some of which meet criteria for influenza-like illness.

A larger study that included mostly immunocompromised patients concluded that if a pathogen (a respiratory virus or 1 of 3 bacterial pathogens detected by a multiplex PCR panel) was already identified from an NP sample, BAL testing is unlikely to provide additional information; however, a significant number (20%) of subjects had a pathogen detected in the BAL without a positive NP sample [6] .

later-on the day I was scheduled to start the clinical portion of my medical training-there were 418 700 confirmed cases of COVID-19 globally [1] . By that time, many courses had started remote instruction, most research laboratories had been closed to all nonessential personnel, and medical school core clerkships had been temporarily canceled, all in an effort to decrease student exposure to COVID-19 and help "flatten the curve. But as a medical student eager to reenter the world of clinical care, the personal stories from the communities that would be most impacted by this relentless pathogen soon consumed my thoughts. Few other events before have so poignantly highlighted the global nature of health, the vulnerability of certain populations around the world, and the need for more infectious disease specialists. But the importance of infectious disease specialists will not end once the number of newly diagnosed COVID-19 cases starts to decrease. To protect those communities, we need more infectious disease specialists. abstract: nan url: https://www.ncbi.nlm.nih.gov/pubmed/32277235/ doi: 10.1093/infdis/jiaa178 id: cord-003115-y40knklf author: Amlabu, Emmanuel title: Functional Characterization of Plasmodium falciparum Surface-Related Antigen as a Potential Blood-Stage Vaccine Target date: 2018-09-01 words: 4943.0 sentences: 260.0 pages: flesch: 34.0 cache: ./cache/cord-003115-y40knklf.txt txt: ./txt/cord-003115-y40knklf.txt summary: The antibodies (α-PfSRA P1, α-PfSRA P2, and α-PfSRA P3) consistently detected multiple processed fragments (17, 32 , and 58 kDa) of the native PfSRA in ring-stage invasion supernatants ( Figure 1B , II-V) or parasite culture supernatants ( Figure 1C , I-IV) and schizont lysates ( Figure 1D , I-IV). falciparum asexual stages by IFAs showed that all α-PfSRA peptide antibodies labeled the surface membranes of merozoites in intact schizonts and released merozoites, respectively (Figure 2A -C). The 3 PfSRA peptide antibodies from rabbits specifically detected breakdown products of native PfSRA in ring-stage invasion supernatant or parasite culture supernatant and schizont lysates. Sequential processing of merozoite surface proteins during and after erythrocyte invasion by Plasmodium falciparum Plasmodium falciparum merozoite surface antigen, PfRH5, elicits detectable levels of invasion-inhibiting antibodies in humans Analysis of antibodies directed against merozoite surface protein 1 of the human malaria parasite Plasmodium falciparum abstract: Plasmodium falciparum erythrocyte invasion is a multistep process that involves a spectrum of interactions that are not well characterized. We have characterized a 113-kDa immunogenic protein, PF3D7_1431400 (PF14_0293), that possesses coiled-coil structures. The protein is localized on the surfaces of both merozoites and gametocytes, hence the name Plasmodium falciparum surface-related antigen (PfSRA). The processed 32-kDa fragment of PfSRA binds normal human erythrocytes with different sensitivities to enzyme treatments. Temporal imaging from initial attachment to internalization of viable merozoites revealed that a fragment of PfSRA, along with PfMSP1(19,) is internalized after invasion. Moreover, parasite growth inhibition assays showed that PfSRA P1 antibodies potently inhibited erythrocyte invasion of both sialic acid–dependent and –independent parasite strains. Also, immunoepidemiological studies show that malaria-infected populations have naturally acquired antibodies against PfSRA. Overall, the results demonstrate that PfSRA has the structural and functional characteristics of a very promising target for vaccine development. url: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6057521/ doi: 10.1093/infdis/jiy222 id: cord-011710-rz23ozxb author: Aoki, Fred Y. title: The Beneficial Effects of Neuraminidase Inhibitor Drug Therapy on Severe Patient Outcomes During the 2009–2010 Influenza A Virus Subtype H1N1 Pandemic date: 2013-02-15 words: nan sentences: nan pages: flesch: nan cache: txt: summary: abstract: nan url: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7313909/ doi: 10.1093/infdis/jis727 id: cord-003171-z22ekgtv author: Babu, Tara M title: Population Serologic Immunity to Human and Avian H2N2 Viruses in the United States and Hong Kong for Pandemic Risk Assessment date: 2018-10-01 words: nan sentences: nan pages: flesch: nan cache: txt: summary: abstract: BACKGROUND: Influenza A pandemics cause significant mortality and morbidity. H2N2 viruses have caused a prior pandemic, and are circulating in avian reservoirs. The age-related frequency of current population immunity to H2 viruses was evaluated. METHODS: Hemagglutinin inhibition (HAI) assays against historical human and recent avian influenza A(H2N2) viruses were performed across age groups in Rochester, New York, and Hong Kong, China. The impact of existing cross-reactive HAI immunity on the effective reproduction number was modeled. RESULTS: One hundred fifty individual sera from Rochester and 295 from Hong Kong were included. Eighty-five percent of patients born in Rochester and Hong Kong before 1968 had HAI titers ≥1:40 against A/Singapore/1/57, and >50% had titers ≥1:40 against A/Berkeley/1/68. The frequency of titers ≥1:40 to avian H2N2 A/mallard/England/727/06 and A/mallard/Netherlands/14/07 in subjects born before 1957 was 62% and 24%, respectively. There were no H2 HAI titers >1:40 in individuals born after 1968. These levels of seroprevalence reduce the initial reproduction number of A/Singapore/1/1957 or A/Berkeley/1/68 by 15%–20%. A basic reproduction number (R(0)) of the emerging transmissible virus <1.2 predicts a preventable pandemic. CONCLUSIONS: Population immunity to H2 viruses is insufficient to block epidemic spread of H2 virus.

World Health Organization (WHO) has issued guidelines for contact and droplet precautions for Healthcare Workers (HCWs) caring for suspected COVID-19 patients, whilst the US Centre for Disease Control (CDC) has recommended airborne precautions. The 1 – 2 m (≈3 – 6 ft) rule of spatial separation is central to droplet precautions and assumes large droplets do not travel further than 2 m (≈6 ft). We aimed to review the evidence for horizontal distance travelled by droplets and the guidelines issued by the World Health Organization (WHO), US Center for Diseases Control (CDC) and European Centre for Disease Prevention and Control (ECDC) on respiratory protection for COVID-19. We found that the evidence base for current guidelines is sparse, and the available data do not support the 1 – 2 m (≈3 – 6 ft) rule of spatial separation. Of ten studies on horizontal droplet distance, eight showed droplets travel more than 2 m (≈6 ft), in some cases more than 8 meters (≈26 ft). Several studies of SARS-CoV-2 support aerosol transmission and one study documented virus at a distance of 4 meters (≈13 ft) from the patient. Moreover, evidence suggests infections cannot neatly be separated into the dichotomy of droplet versus airborne transmission routes. Available studies also show that SARS-CoV-2 can be detected in the air, 3 hours after aeroslisation. The weight of combined evidence supports airborne precautions for the occupational health and safety of health workers treating patients with COVID-19. url: https://doi.org/10.1093/infdis/jiaa189 doi: 10.1093/infdis/jiaa189 id: cord-288821-nalulzfo author: Bastien, Nathalie title: Human Coronavirus NL63 Infection in Canada date: 2005-02-15 words: nan sentences: nan pages: flesch: nan cache: txt: summary: abstract: The isolation of human coronavirus NL63 (HCoV-NL63) in The Netherlands raised questions about its contribution to respiratory illness.

We therefore studied patients during a two-year period at a treatment center in rural Bangladesh to determine the frequency, severity, and seasonality of diarrhea associated with ETEC, rotavirus, and other enteric agents. V. cholerae group 0: 1 was rarely identified for children less than two years of age but was an important pathogen in older children and adults, while non-group 0: 1 vibrios were found in the stools of 4010-11 010 of the patients of each age group for both years of the study. ETEC organisms were the pathogens most frequently isolated from patients of all ages and were the second most frequently isolated (after rotavirus) from young children coming to the treatment center in rural Bangladesh. abstract: Enteric pathogens associated with diarrhea were studied for two years at a diarrhea treatment center in rural Bangladesh. Enterotoxigenic Escherichia coli (ETEC) was the most frequently identified pathogen for patients of all ages. Rotavirus and ETEC were isolated from ∼50% and ∼25%, respectively, of patients less than two years of age. A bacterial or viral pathogen was identified for 70% of these young children and for 56% of all patients with diarrhea. Most ETEC isolates were obtained in the hot dry months of March and April and the hot wet months of August and September. Rotavirus identification peaked in the cool dry months of December and January, but infected patients were found year-round. The low case-fatality rates for patients with watery diarrhea and substantial dehydration further document the usefulness of treating patients with diarrhea with either a glucose- or sucrose-base electrolyte solution such as those used in this treatment center. url: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7109920/ doi: 10.1093/infdis/142.5.660 id: cord-258905-0hgdtalg author: Bond, Katherine title: Evaluation of Serological Tests for SARS-CoV-2: Implications for Serology Testing in a Low-Prevalence Setting date: 2020-08-06 words: 3663.0 sentences: 176.0 pages: flesch: 44.0 cache: ./cache/cord-258905-0hgdtalg.txt txt: ./txt/cord-258905-0hgdtalg.txt summary: METHODS: Performance characteristics for 5 PoCT lateral flow devices approved for use in Australia were compared to a commercial enzyme immunoassay (ELISA) and a recently described novel surrogate virus neutralization test (sVNT). A testing panel was specifically developed to test PoCT devices for this study (Supplementary Material), consisting of 3 patient populations: (1) sera from 91 patients with SARS-CoV-2 detected by RT-PCR from upper and/or lower respiratory tract specimens; (2) sera from 36 patients with seasonal coronavirus infections or other acute infections (eg, dengue, cytomegalovirus, Epstein-Barr virus); and (3) serum from a random cohort (56 patients) of the Australian population obtained in 2018. In this study, we assessed the performance characteristics of 5 serological PoCT, a commercial ELISA, and a commercial novel sVNT against a large serum panel from a cohort of over 100 patients with RT-PCR-confirmed SARS-CoV-2. abstract: BACKGROUND: Robust serological assays are essential for long-term control of the COVID-19 pandemic. Many recently released point-of-care (PoCT) serological assays have been distributed with little premarket validation. METHODS: Performance characteristics for 5 PoCT lateral flow devices approved for use in Australia were compared to a commercial enzyme immunoassay (ELISA) and a recently described novel surrogate virus neutralization test (sVNT). RESULTS: Sensitivities for PoCT ranged from 51.8% (95% confidence interval [CI], 43.1%–60.4%) to 67.9% (95% CI, 59.4%–75.6%), and specificities from 95.6% (95% CI, 89.2%–98.8%) to 100.0% (95% CI, 96.1%–100.0%). ELISA sensitivity for IgA or IgG detection was 67.9% (95% CI, 59.4%–75.6%), increasing to 93.8% (95% CI, 85.0%–98.3%) for samples >14 days post symptom onset. sVNT sensitivity was 60.9% (95% CI, 53.2%–68.4%), rising to 91.2% (95% CI, 81.8%–96.7%) for samples >14 days post symptom onset, with specificity 94.4% (95% CI, 89.2%–97.5%). CONCLUSIONS: Performance characteristics for COVID-19 serological assays were generally lower than those reported by manufacturers. Timing of specimen collection relative to onset of illness or infection is crucial in reporting of performance characteristics for COVID-19 serological assays. The optimal algorithm for implementing serological testing for COVID-19 remains to be determined, particularly in low-prevalence settings. url: https://www.ncbi.nlm.nih.gov/pubmed/32761124/ doi: 10.1093/infdis/jiaa467 id: cord-346411-d2re00r9 author: Boonyaratanakornkit, Jim title: Predictive Value of Respiratory Viral Detection in the Upper Respiratory Tract for Infection of the Lower Respiratory Tract With Hematopoietic Stem Cell Transplantation date: 2020-02-01 words: 4416.0 sentences: 200.0 pages: flesch: 43.0 cache: ./cache/cord-346411-d2re00r9.txt txt: ./txt/cord-346411-d2re00r9.txt summary: In a small study of adults, the majority of which were HCT recipients or had a hematologic malignancy, with matched NP and BAL specimens, PCR-based NP testing for respiratory viruses in patients with clinical evidence of LRT disease had a high negative predictive value (NPV) and a lower positive predictive value (PPV) [5] . A larger study that included mostly immunocompromised patients concluded that if a pathogen (a respiratory virus or 1 of 3 bacterial pathogens detected by a multiplex PCR panel) was already identified from an NP sample, BAL testing is unlikely to provide additional information; however, a significant number (20%) of subjects had a pathogen detected in the BAL without a positive NP sample [6] . In the present study, we characterized the rates of discordance in respiratory viral detection between matched URT and LRT samples in a large cohort of HCT candidates/recipients who underwent BAL for suspected LRTI and had concomitant URT testing. abstract: BACKGROUND: Hematopoietic cell transplant (HCT) recipients are frequently infected with respiratory viruses (RVs) in the upper respiratory tract (URT), but the concordance between URT and lower respiratory tract (LRT) RV detection is not well characterized. METHODS: Hematopoietic cell transplant candidates and recipients with respiratory symptoms and LRT and URT RV testing via multiplex PCR from 2009 to 2016 were included. Logistic regression models were used to analyze risk factors for LRT RV detection. RESULTS: Two-hundred thirty-five HCT candidates or recipients had URT and LRT RV testing within 3 days. Among 115 subjects (49%) positive for a RV, 37% (42 of 115) had discordant sample pairs. Forty percent (17 of 42) of discordant pairs were positive in the LRT but negative in the URT. Discordance was common for adenovirus (100%), metapneumovirus (44%), rhinovirus (34%), and parainfluenza virus type 3 (28%); respiratory syncytial virus was highly concordant (92%). Likelihood of LRT detection was increased with URT detection (oods ratio [OR] = 73.7; 95% confidence interval [CI], 26.7–204) and in cytomegalovirus-positive recipients (OR = 3.70; 95% CI, 1.30–10.0). CONCLUSIONS: High rates of discordance were observed for certain RVs. Bronchoalveolar lavage sampling may provide useful diagnostic information to guide management in symptomatic HCT candidates and recipients. url: https://doi.org/10.1093/infdis/jiz470 doi: 10.1093/infdis/jiz470 id: cord-320764-p4ydngag author: Breiman, Robert F. title: Surveillance for Respiratory Infections in Low- and Middle-Income Countries: Experience From the Centers for Disease Control and Prevention's Global Disease Detection International Emerging Infections Program date: 2013-12-15 words: nan sentences: nan pages: flesch: nan cache: txt: summary: abstract: nan url: https://doi.org/10.1093/infdis/jit462 doi: 10.1093/infdis/jit462 id: cord-341548-gazsszs6 author: Buscho, R.

Because of the high prevalence and morbidity of chronic bronchitis among patients of Veterans Administration Hospitals, we have conducted surveillance of one of these groups to assess the impact of respiratory tract infections on the natural course of this disease and to investigate further the occurrence and relative importance of viruses and mycoplasmas in exacerbations [3] . Evidence of viral and Mycoplasma pneumoniae infections (obtained mainly by serologic testing and to a lesser extent by isolation of organisms) was correlated with the pattern of clinical disease in patients with chronic bronchitis. pneumoniae were detected in 50 (30.1%) of 166 exacerbations of chronic bronchitis in the 46 adult patients studied (table 2) . abstract: The association of viral and Mycoplasma pneumoniae infections with acute exacerbations of chronic bronchitis was studied by serologic or isolation techniques in 46 adult men during the five years from 1964 through 1968. Serologic evidence of viral or M. pneumoniae infection was detected in 25% of 166 episodes of exacerbation and 14% of 138 remission periods (P = 0.02). Influenza A virus, parainfluenza virus type 3, and coronavirus OC43 predominated; infections with other viruses were infrequent. Infection with M. pneumoniae was detected serologically in four patients, but this organism was never isolated from sputum specimens. Rhinoviruses were isolated from frozen-stored sputum specimens in 2.7% of the episodes of exacerbation and from 0.55% of the remission intervals (P not significant). These data suggest that although exacerbations of chronic bronchitis may be accompanied by viral and M. pneumoniae infections, patients with chronic bronchitis also acquire such infections without a worsening of their respiratory status. url: https://www.ncbi.nlm.nih.gov/pubmed/206630/ doi: 10.1093/infdis/137.4.377 id: cord-007013-tlvgyzft author: Chan, Kok Fei title: Investigating Viral Interference Between Influenza A Virus and Human Respiratory Syncytial Virus in a Ferret Model of Infection date: 2018-08-01 words: 4939.0 sentences: 320.0 pages: flesch: 49.0 cache: ./cache/cord-007013-tlvgyzft.txt txt: ./txt/cord-007013-tlvgyzft.txt summary: Previously, we used the ferret model to demonstrate that viral interference can occur following infection with human influenza A and B viruses and will prevent, delay, or limit subsequent infection with an influenza virus of a different type, subtype, or lineage [10, 11] . The peak of hRSV shedding was delayed in ferrets infected with A(H1N1)pdm09 followed by hRSV as compared to control animals infected with hRSV alone (median, 8 vs 6 days; P = .0091 by the Mann-Whitney test; Figure 2Ci ). The median duration of A(H1N1)pdm09 shedding was increased in ferrets infected with hRSV followed by A(H1N1)pdm09 as compared to control animals infected with A(H1N1)pdm09 alone (8 vs 7 days; P = .0196 by the Mann-Whitney test; Figure 2Civ ). Notably, increased expression of inflammatory mediators following infection with influenza virus as compared to hRSV has been observed in studies assessing human clinical samples and in vitro airway epithelial cell cultures [36] [37] [38] [39] . abstract: Epidemiological studies have observed that the seasonal peak incidence of influenza virus infection is sometimes separate from the peak incidence of human respiratory syncytial virus (hRSV) infection, with the peak incidence of hRSV infection delayed. This is proposed to be due to viral interference, whereby infection with one virus prevents or delays infection with a different virus. We investigated viral interference between hRSV and 2009 pandemic influenza A(H1N1) virus (A[H1N1]pdm09) in the ferret model. Infection with A(H1N1)pdm09 prevented subsequent infection with hRSV. Infection with hRSV reduced morbidity attributed to infection with A(H1N1)pdm09 but not infection, even when an increased inoculum dose of hRSV was used. Notably, infection with A(H1N1)pdm09 induced higher levels of proinflammatory cytokines, chemokines, and immune mediators in the ferret than hRSV. Minimal cross-reactive serological responses or interferon γ–expressing cells were induced by either virus ≥14 days after infection. These data indicate that antigen-independent mechanisms may drive viral interference between unrelated respiratory viruses that can limit subsequent infection or disease. url: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7107400/ doi: 10.1093/infdis/jiy184 id: cord-335375-n6q70o35 author: Chan, Paul K.

Changes in severe acute respiratory syndrome-associated coronavirus-specific IgG antibody avidity in paired serum samples ples were measured by an in-house indirect immunofluorescence assay that has been described elsewhere [12] . Of the 45 samples collected р50 days after fever onset, only 18 (40.0%) were positive for anti-SARS-CoV IgM antibody, as determined by the ELISARS assay. Of the 26 paired samples, only 6 (23.1%) showed a significant (у4-fold) increase in anti-SARS-CoV IgG antibody titer (as determined by an in-house indirect immunofluorescence assay) from the first to the second sample, a result that could be regarded as evidence of recent infection. Our data show that anti-SARS-CoV IgG antibody avidity is low during primary infection and increases with time in a unidirectional manner. abstract: The maturation of virus-specific immunoglobulin G avidity during severe acute respiratory syndrome–associated coronavirus infection was examined. The avidity indices were low (mean ± SD, 30.8% ± 11.6%) among serum samples collected ⩽50 days after fever onset, intermediate (mean ± SD, 52.1% ± 14.1%) among samples collected between days 51 and 90, and high (mean ± SD, 78.1% ± 8.0%) among samples collected after day 90. Avidity indices of 40% and 55% could be considered as cutoff values for determination of recent (⩽50 days) and past (>65 days) infection, respectively.

We reanalyzed the Singapore Armed Forces FRI surveillance program data by using survival analyses to assess whether there was any evidence, at the individual level, that infection with particular viruses was conferring short-lived relative cross-protection against subsequent FRI episodes, including those caused by other virus groups. AdV-positive episodes tended to protect against subsequent infection with AdV (P = .090) and also 3 other virus groups All models were adjusted for study year, type of BMT intake, age, ethnicity, smoking history, history of asthma, and influenza vaccination. Infections from the adenovirus and influenza virus families conferred significant cross-protective effects against subsequent FRI episodes relative to other circulating viruses. abstract: BACKGROUND: Few studies have evaluated the relative cross-protection conferred by infection with different groups of viruses through studies of sequential infections in humans. We investigated the presence of short-lived relative cross-protection conferred by specific prior viral infections against subsequent febrile respiratory illness (FRI). METHODS: Men enlisted in basic military training between December 2009 and December 2014 were recruited, with the first FRI as the study entry point. ResPlex II assays and real-time polymerase chain reaction assays were used to detect viral pathogens in nasal wash samples, and survival analyses were performed to determine whether infection with particular viruses conferred short-lived relative cross-protection against FRI. RESULTS: Prior infection with adenovirus (hazard ratio [HR], 0.24; 95% confidence interval [CI], .14–.44) or influenza virus (HR, 0.52; 95% CI, .38–.73) conferred relative protection against subsequent FRI episode. Results were statistically significant even after adjustment for the interval between enlistment and FRI (P < .001). Adenovirus-positive participants with FRI episodes tended to be protected against subsequent infection with adenovirus, coronavirus, enterovirus/rhinovirus, and influenza virus (P = .062–.093), while men with influenza virus–positive FRI episodes tended be protected against subsequent infection with adenovirus (P = .044) and influenza virus (P = .081).

Using an indirect immunofluorescence assay and parallel acute and convalescent serum samples obtained from patients with SARS, tested for IgG antibody to SARS CoV, Peiris et al. In addition, our results indicated that 9 (25.0%) of 36 patients with probable SARS CoV infection had not produced detectable anti-SARS CoV antibody by day 21 after the onset of fever; this implies that 25.0% of patients with SARS might be misdiagnosed by the laboratory confirmation guidelines that WHO currently recommends [5] . abstract: Background. Severe acute respiratory syndrome (SARS) is a novel infectious disease. No information is currently available on host-specific immunity against the SARS coronavirus (CoV), and detailed characteristics of the epidemiology of SARS CoV infection have not been identified. Methods. ELISA was used to detect antibody to SARS CoV. Reverse-transcriptase polymerase chain reaction was used to detect SARS CoV RNA. T cells in peripheral blood of patients were quantified by flow cytometry. Results. Of 36 patients with probable SARS CoV infection, 30 (83.3%) were positive for IgG antibody to SARS CoV; in contrast, only 3 of 48 patients with suspected SARS CoV infection, 0 of 112 patients with fever but without SARS, and 0 of 96 healthy control individuals were positive for it. IgG antibody to SARS CoV was first detected between day 5 and day 47 after onset of illness (mean ± SD, 18.7±10.4). Conclusion. Detection of antibody to SARS CoV is useful in the diagnosis of SARS; however, at the incubation and initial phases of the illness, serological assay is of little value, because of late seroconversion in most patients. url: https://www.ncbi.nlm.nih.gov/pubmed/15031782/ doi: 10.1086/380397 id: cord-270205-fw555w1u author: Cillóniz, Catia title: Pure Viral Sepsis Secondary to Community-Acquired Pneumonia in Adults: Risk and Prognostic Factors date: 2019-10-01 words: 2743.0 sentences: 146.0 pages: flesch: 49.0 cache: ./cache/cord-270205-fw555w1u.txt txt: ./txt/cord-270205-fw555w1u.txt summary: title: Pure Viral Sepsis Secondary to Community-Acquired Pneumonia in Adults: Risk and Prognostic Factors We investigated the risk and prognostic factors of pure viral sepsis in adult patients with community-acquired pneumonia (CAP), using the Sepsis-3 definition.

CONCLUSIONS: Singapore would benefit from more frequent studies of clinical HAdV genotypes to identify patients at risk for severe disease and help guide the use of new antiviral therapies, such as brincidofovir, and potential administration of HAdV 4 and 7 vaccine. Clinical samples previously collected from HAdV-positive patients admitted to Singapore General Hospital (SGH) and KK Women''s and Children''s Hospital (KKH) between 2012 and 2015 were preserved at −80°C and transferred to Duke-NUS Laboratory of One Health Research for study. Human adenovirus-C datasets consisted of 4 novel genomes from Singapore and 22 representative virus isolates from different genotypes (HAdV-C1, HAdV-C2, HAdV-C5, and HAdV-C6). abstract: BACKGROUND: A number of serious human adenovirus (HAdV) outbreaks have been recently reported: HAdV-B7 (Israel, Singapore, and USA), HAdV-B7d (USA and China), HAdV-D8, -D54, and -C2 (Japan), HAdV-B14p1 (USA, Europe, and China), and HAdV-B55 (China, Singapore, and France). METHODS: To understand the epidemiology of HAdV infections in Singapore, we studied 533 HAdV-positive clinical samples collected from 396 pediatric and 137 adult patients in Singapore from 2012 to 2018. Genome sequencing and phylogenetic analyses were performed to identify HAdV genotypes, clonal clusters, and recombinant or novel HAdVs. RESULTS: The most prevalent genotypes identified were HAdV-B3 (35.6%), HAdV-B7 (15.4%), and HAdV-E4 (15.2%). We detected 4 new HAdV-C strains and detected incursions with HAdV-B7 (odds ratio [OR], 14.6; 95% confidence interval [CI], 4.1–52.0) and HAdV-E4 (OR, 13.6; 95% CI, 3.9–46.7) among pediatric patients over time.

Here we quantify how levels of these antibodies change in the months following SARS-CoV-2 infection by examining longitudinal samples collected between ~30 and 152 days post symptom onset from a prospective cohort of 32 recovered individuals with asymptomatic, mild, or moderate-severe disease. Neutralizing antibody titers declined an average of about four-fold from one to four months post symptom onset. This decline in neutralizing antibody titers was accompanied by a decline in total antibodies capable of binding the viral spike or its receptor-binding domain. Importantly, our data are consistent with the expected early immune response to viral infection, where an initial peak in antibody levels is followed by a decline to a lower plateau. Additional studies of long-lived B-cells and antibody titers over longer time frames are necessary to determine the durability of immunity to SARS-CoV-2. url: https://www.ncbi.nlm.nih.gov/pubmed/33000143/ doi: 10.1093/infdis/jiaa618 id: cord-007188-tcq8lnwg author: Cunningham, Anthony L. title: Gastrointestinal Viral Infections in Homosexual Men Who were Symptomatic and Seropositive for Human Immunodeficiency Virus date: 1988-08-17 words: 2268.0 sentences: 120.0 pages: flesch: 45.0 cache: ./cache/cord-007188-tcq8lnwg.txt txt: ./txt/cord-007188-tcq8lnwg.txt summary: Gastrointestinal viruses, predominantly rotaviruses and adenoviruses, were detected by enzyme-linked immunosorbent assay, electron microscopy, or cell culture in >50% of two groups of homosexual men with symptomatic human immunodeficiency virus (HIV) infection, who did (54%) or did not (50%) have diarrhea. We report here the detection of viruses from the stools of a large proportion of patients with symptomatic HIV infection (AIDS, ARC, and POL) and acute or chronic diarrhea when no other microbial pathogen could be identified. In this study we showed that patients with AIDS or ARC may present with acute diarrhea or exacerbations of chronic diarrhea and that in patients with symptomatic HIV infection and diarrhea, >50% excreted gastrointestinal viruses. These high detection rates for rotavirus and adenovirus in patients with ARC or AIDS-OI are similar to those observed in marrow transplant recipients who also have a T cell immunodeficiency and often have gastrointestinal mucosal damage from graft-versus-host disease [4] . abstract: Gastrointestinal viruses, predominantly rotaviruses and adenoviruses, were detected by enzyme-linked immunosorbent assay, electron microscopy, or cell culture in >50% of two groups of homosexual men with symptomatic human immunodeficiency virus (HIV) infection, who did (54%) or did not (50%) have diarrhea. Lower detection rates were observed in HIV-seronegative (15%) and asymptomatic HIV-seropositive (16%) men. In the patients with diarrhea, 95% of the isolates of virus were found in the most immuno suppressed patients, those patients with AIDS-related complex or opportunistic infections associated with AIDS. High excretion rates of these viruses are probably associated with both anal-oral transmission and immunosuppression. These viruses apparently cause acute episodes or relapses of diarrhea in some patients but may be co-pathogens or noncontributory to chronic diarrhea in others. url: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7109796/ doi: 10.1093/infdis/158.2.386 id: cord-324701-7vjdlt1v author: Dahlmann, Franziska title: Analysis of Ebola Virus Entry Into Macrophages date: 2015-10-01 words: 5322.0 sentences: 273.0 pages: flesch: 49.0 cache: ./cache/cord-324701-7vjdlt1v.txt txt: ./txt/cord-324701-7vjdlt1v.txt summary: Lectins, TAM receptor tyrosine kinases (Tyro3, Axl, Mer), T cell immunoglobulin and mucin domain (TIM) proteins, integrins, and Niemann-Pick C1 (NPC1) have been reported to promote entry of ebolaviruses into certain cellular systems. Here, we show that mannose-specific lectins, TIM-1 and Axl augment entry into certain cell lines but do not contribute to Ebola virus (EBOV)-glycoprotein (GP)–driven transduction of macrophages. To confirm and extend these observations, we compared the ability of lectins, TIM proteins, and the TAM family member Axl to augment EBOV-GP-driven entry into 293T cells, which can be efficiently transfected and are highly susceptible to transduction mediated by ebolavirus GPs [11] . Quantitative RT-PCR revealed that less Axl and TIM-1 mRNA is produced in MDMs compared with susceptible cell lines, and siRNA-knock-down showed that expression of these factors is dispensable for GP-driven entry into MDMs. In contrast, Mer but not Axl expression was required for efficient GPdriven transduction and EBOV infection of MDMs. Similarly, Mer but not Axl or Tyro3 was found to be essential for efficient phagocytosis of apoptotic cells by macrophages [46] , indicating that Mer is the TAM receptor kinase active in macrophages. abstract: Ebolaviruses constitute a public health threat, particularly in Central and Western Africa. Host cell factors required for spread of ebolaviruses may serve as targets for antiviral intervention. Lectins, TAM receptor tyrosine kinases (Tyro3, Axl, Mer), T cell immunoglobulin and mucin domain (TIM) proteins, integrins, and Niemann-Pick C1 (NPC1) have been reported to promote entry of ebolaviruses into certain cellular systems. However, the factors used by ebolaviruses to invade macrophages, major viral targets, are poorly defined. Here, we show that mannose-specific lectins, TIM-1 and Axl augment entry into certain cell lines but do not contribute to Ebola virus (EBOV)-glycoprotein (GP)–driven transduction of macrophages. In contrast, expression of Mer, integrin αV, and NPC1 was required for efficient GP-mediated transduction and EBOV infection of macrophages. These results define cellular factors hijacked by EBOV for entry into macrophages and, considering that Mer and integrin αV promote phagocytosis of apoptotic cells, support the concept that EBOV relies on apoptotic mimicry to invade target cells. url: https://doi.org/10.1093/infdis/jiv140 doi: 10.1093/infdis/jiv140 id: cord-313000-as507p4t author: Dare, Ryan K. title: Human Coronavirus Infections in Rural Thailand: A Comprehensive Study Using Real-Time Reverse-Transcription Polymerase Chain Reaction Assays date: 2007-11-01 words: nan sentences: nan pages: flesch: nan cache: txt: summary: abstract: Background. We sought to determine whether infections with human coronaviruses (HCoVs) 229E, OC43, HKU1, and NL63 are associated with pneumonia and to define the epidemiology of HCoV infection in rural Thailand. Methods. We developed a real-time reverse-transcription polymerase chain reaction (RT-PCR) assay panel for the recognized HCoV types and compared HCoV infections in patients hospitalized with pneumonia, outpatients with influenza-like illness, and asymptomatic control patients between September 2003 and August 2005. Results. During study year 1, 43 (5.9%) of 734 patients with pneumonia had HCoV infections; 72.1% of the infections were with OC43. During study year 2, when control patients were available, 21 (1.8%) of 1156 patients with pneumonia, 12 (2.3%) of 513 outpatients, and 6 (2.1%) of 281 control patients had HCoV infections. Compared with infection in control patients, infection with any HCoV type or with all types combined was not associated with pneumonia (adjusted odds ratio for all HCoV types, 0.67 [95% confidence interval, 0.26–1.75]; P= .40 ). HCoV infections were detected throughout both study years; 93.6% of OC43 infections in the first year occurred from January through March. Conclusions. HCoV infections were infrequently detected in rural Thailand by use of sensitive real-time RTPCR assays. We found no association between HCoV infection and illness. However, we noted year-to-year variation in the prevalence of HCoV strains, which likely influenced our results. url: https://www.ncbi.nlm.nih.gov/pubmed/17922396/ doi: 10.1086/521308 id: cord-275108-snqbrxgr author: Daverio, Marco title: Testing for Novel Coronavirus Antibodies: A Necessary Adjunct date: 2020-05-22 words: nan sentences: nan pages: flesch: nan cache: txt: summary: abstract: nan url: https://www.ncbi.nlm.nih.gov/pubmed/32442248/ doi: 10.1093/infdis/jiaa283 id: cord-266695-ktbgm0p9 author: Dawson, Liza title: SARS-CoV-2 Human Challenge Trials: Too Risky, Too Soon date: 2020-06-04 words: 1452.0 sentences: 109.0 pages: flesch: 50.0 cache: ./cache/cord-266695-ktbgm0p9.txt txt: ./txt/cord-266695-ktbgm0p9.txt summary: have recently argued that researchers should consider conducting SARS-CoV-2 human challenge studies to hasten vaccine development [1] . However, we disagree that SARS-CoV-2 challenge studies are ethically appropriate at this time, for three reasons: 1) current scientific knowledge of SARS-CoV-2 infection is insufficient to manage risks; 2) autonomous decision-making, while necessary, does not override concerns about risk; and 3) undertaking challenge studies now would imperil confidence in the research enterprise, potentially undermining the global response to the COVID-19 pandemic. Current scientific knowledge is insufficient to manage the risks of severe disease or death of volunteers in SARS-CoV-2 human challenge studies, especially in terms of selecting low risk volunteers [2] . It is not obvious that the possible benefits of developing a successful vaccine in less time justify the risks SARS-CoV-2 challenge studies, as Eyal and colleagues suggest.

Definite diagnosis of Leishmania infections is based on demonstration of the parasite by microscopic analysis of tissue biopsy specimens or aspirate samples. However, microscopy generally shows low sensitivity and requires invasive sampling. Methods. We describe here the development of a simple and rapid test for the detection of polymerase chain reaction-amplified Leishmania DNA. A phase 1 evaluation of the text was conducted in clinical samples from 60 nonendemic and 45 endemic control subjects and from 44 patients with confirmed cutaneous leishmaniasis (CL), 12 with mucocutaneous leishmaniasis (MCL), and 43 with visceral leishmaniasis (VL) from Peru, Kenya, and Sudan. Results. The lower detection limits of the assay are 10 fg of Leishmania DNA and 1 parasite in 180 µL of blood. The specificity was 98.3% (95% confidence interval [CI], 91.1%–99.7%) and 95.6% (95% CI, 85.2%–98.8%) for nonendemic and endemic control samples, respectively, and the sensitivity was 93.2% (95% CI, 81.8%–97.7%), 91.7% (95% CI, 64.6%–98.5%), and 86% (95% CI, 72.7%–93.4%) for lesions from patients with CL or MCL and blood from patients with VL, respectively. Conclusions. The Leishmania OligoC-TesT showed high specificity and sensitivity in clinical samples and was able to detect the parasite in samples obtained by less invasive means, such as blood, lymph, and lesion scrapings. The assay is a promising new tool for simplified and standardized molecular detection of Leishmania parasites. url: https://www.ncbi.nlm.nih.gov/pubmed/18816188/ doi: 10.1086/592509 id: cord-275863-qos9vu3r author: Dejnirattisai, Wanwisa title: Lectin Switching During Dengue Virus Infection date: 2011-06-15 words: 4488.0 sentences: 193.0 pages: flesch: 51.0 cache: ./cache/cord-275863-qos9vu3r.txt txt: ./txt/cord-275863-qos9vu3r.txt summary: In this report we have studied the interaction of dengue viruses produced in insect cells, tumor cell lines, and primary human dendritic cells (DCs) with DC-SIGN and L-SIGN. To formally prove that the loss of infection of DCs was a result of the loss of affinity of DC-produced virus for DC-SIGN, we went on to test infection on 3T3 cells expressing DC-SIGN and included in these assays the related C-type lectin L-SIGN ( Figure 3A ), which has also been reported to be a receptor for dengue virus. C6/36-and DC-derived viruses were incubated with increasing levels of pooled convalescent dengue immune serum and subsequently used to infect U937, a monocyte cell line that expresses the Fc receptor and which shows relatively low infectivity without the presence of enhancing antibodies. Viruses produced in both DCs and insect cells were susceptible to enhancement, over the same range of antibody concentrations, showing that DC-produced virus could exploit ADE to replicate in individuals undergoing a secondary dengue infection ( Figure 6A ). abstract: Dengue virus receptors are relatively poorly characterized, but there has been recent interest in 2 C-type lectin molecules, dendritic cell–specific intercellular adhesion molecule 3 (ICAM-3)–grabbing nonintegrin (DC-SIGN) and its close homologue liver/lymph node–specific ICAM-3–grabbing integrin (L-SIGN), which can both bind dengue and promote infection. In this report we have studied the interaction of dengue viruses produced in insect cells, tumor cell lines, and primary human dendritic cells (DCs) with DC-SIGN and L-SIGN. Virus produced in primary DCs is unable to interact with DC-SIGN but remains infectious for L-SIGN–expressing cells. Skin-resident DCs may thus be a site of initial infection by insect-produced virus, but DCs will likely not participate in large-scale virus replication during dengue infection. These results reveal that differential glycosylation of dengue virus envelope protein is highly dependent on cell state and suggest that studies of virus tropism using virus prepared in insect cells or tumor cell lines should be interpreted with caution. url: https://www.ncbi.nlm.nih.gov/pubmed/21606536/ doi: 10.1093/infdis/jir173 id: cord-289406-54vyzxjf author: Edwards, Suzanne title: An Experimental Model for Myocarditis and Congestive Heart Failure after Rabbit Coronavirus Infection date: 1992-01-17 words: 3503.0 sentences: 217.0 pages: flesch: 48.0 cache: ./cache/cord-289406-54vyzxjf.txt txt: ./txt/cord-289406-54vyzxjf.txt summary: In a model for virus-induced myocarditis and congestive heart failure, rabbit coronavirus infection was divided into acute (days 2–5) and subacute (days 6–12) phases on the basis of day of death and pathologic findings.

The severity of these changes increased in the subacute phase. Pleural effusion and congestion of the lungs and liver were also present at this time. Myocarditis was detected by day 9 and peaked by day 12. Heart weights and heart weight-to-body weight ratios were increased, and dilation of the right ventricular cavity became prominent early in infection and persisted. In contrast, dilation of the left ventricle occurred late in the subacute stage. Virus was isolated from infected hearts between days 2 and 12.

The etiological agents responsible for a substantial proportion of respiratory tract diseases have not been identified. We sought to determine whether novel human coronaviruses (HCoVs) are circulating in New Haven, Connecticut, and, if so, whether they are associated with respiratory tract disease in infants and young children. Methods. We developed a polymerase chain reaction (PCR)-based approach for screening specimens from the respiratory tracts of symptomatic children. PCR probes that target regions of the replicase 1a gene that are conserved among genetically diverse animal CoVs and HCoVs were designed. Using these probes, we identified genomic sequences of a novel HCoV, designated “New Haven coronavirus” (HCoV-NH). Thereafter, we designed specific probes to screen respiratory specimens from children <5 years old for this novel HCoV. Clinical features associated with HCoV-NH infection were identified. Results. Seventy-nine (8.8%) of 895 children tested positive for HCoV-NH. Cough, rhinorrhea, tachypnea, fever, abnormal breath sounds, and hypoxia were the most common findings associated with HCoV-NH infection. Sequence analysis revealed that HCoV-NH is closely related to a novel HCoV recently reported in The Netherlands. Conclusions. The novel HCoVs identified in New Haven and The Netherlands are similar and likely represent the same species. This newly discovered virus may have worldwide distribution and may account for a significant proportion of respiratory tract disease in infants and young children. url: https://www.ncbi.nlm.nih.gov/pubmed/15655770/ doi: 10.1086/428138 id: cord-313344-rqvi2ksc author: Farcas, Gabriella A. title: Fatal Severe Acute Respiratory Syndrome Is Associated with Multiorgan Involvement by Coronavirus date: 2005-01-15 words: nan sentences: nan pages: flesch: nan cache: txt: summary: abstract: Severe acute respiratory syndrome (SARS) is characterized by pulmonary compromise; however, patients often have evidence of other organ dysfunction that may reflect extrapulmonary dissemination of SARS coronavirus (SARS-CoV). We report on the distribution and viral load of SARS-CoV in multiple organ samples from patients who died of SARS during the Toronto outbreak. SARS-CoV was detected in lung (100%), bowel (73%), liver (41%), and kidney (38%) in 19 patients who died of SARS, with the highest viral loads observed in lung (1.0 × 10(10) copies/g) and bowel (2.7 × 10(9) copies/g). Fatal SARS was associated with multiorgan viral dissemination in a distribution that has implications for disease manifestation, viral shedding, and transmission. url: https://www.ncbi.nlm.nih.gov/pubmed/15609228/ doi: 10.1086/426870 id: cord-312552-udky2ko7 author: Fouque, Florence title: Introduction to a Landscape Analysis of Multisectoral Approaches for Prevention and Control of Infectious and Vector-Borne Diseases date: 2020-10-29 words: nan sentences: nan pages: flesch: nan cache: txt: summary: abstract: The Swiss Development Cooperation, Canada’s International Development Research Centre, the Swiss Tropical Public Health Institute, and the UNICEF/United Nations Development Programme (UNDP)/World Bank/World Health Organization (WHO) Special Programme for Research and Training in Tropical Diseases (TDR) collaborated on a project to review, understand and promote the use of multisectoral approaches (MSAs) in the prevention and control of vector-borne diseases (VBDs). The objectives of the project were to support a landscape analysis of how MSAs have been used in the prevention and control of VBDs; to develop a theoretical framework for guiding the implementation of interventions; and to test the recommendations in real-life conditions. To realize these objectives, the project supported several activities, including commissioning a series of scientific reviews on MSAs in 5 thematic areas, sharing the key findings of these reviews in workshops and events, and developing a guidance framework for the implementation of MSAs. These activities have produced the theoretical framework that will be tested in real-life conditions through the support of case studies. The collaboration on implementing multisectoral activities against VBDs will continue among TDR, the Swiss Tropical Public Health Institute, and new partners such as the WHO Water Sanitation and Hygiene Group, UNDP, and UN-Habitat, in order to face the challenges identified and propose solutions tailored to specific contexts. The prevention and control of VBDs require strong and adapted MSAs with the full participation of all relevant sectors. url: https://doi.org/10.1093/infdis/jiaa489 doi: 10.1093/infdis/jiaa489 id: cord-011708-naezfola author: Frank, Gregory M. title: Infectious Diseases Society of America and Gain-of-Function Experiments With Pathogens Having Pandemic Potential date: 2016-05-01 words: 2163.0 sentences: 85.0 pages: flesch: 39.0 cache: ./cache/cord-011708-naezfola.txt txt: ./txt/cord-011708-naezfola.txt summary: To that end, we highlight below 6 key recommendations that the IDSA recently shared with the NSABB as we discuss how best to assess the benefits and risk of GOF research of concern. The IDSA strongly urges the NSABB to narrow its definition of GOF research to be considered for risk-benefit assessment (RBA), to avoid this inadvertent capture of low-risk research, which is not mentioned in the White House Office of Science and Technology Policy''s original description of the types of research that should be included in the deliberative process. The IDSA strongly supports these actions and also urges the NSABB to consider seeking additional perspectives to inform the RBA process, including those of a range of experts in vaccine development, microbial risk assessment, and public health response; physicians whose work is primarily clinical; and the public.

We detected human bocavirus (HBoV) infection in 4.5% of hospitalized patients with pneumonia in rural Thailand. However, the role of HBoV as a pathogen is unclear. Methods. We compared HBoV infection in patients with pneumonia with that in asymptomatic control patients enrolled between 1 September 2004 and 31 August 2005 in the same hospitals in Thailand.We examined outpatients with influenza-like illness for HBoV infection and tested for 13 additional respiratory viruses. Epidemiologic and clinical characteristics of HBoV infection are described. Results. HBoV infection was detected in 20 (3.9%) of 512 outpatients and 3 (1%) of 280 control patients. Coinfection with other viruses was detected in 83% of patients with pneumonia and in 90% of outpatients. Compared with control patients, HBoV infection was significantly associated with pneumonia requiring hospitalization (adjusted odds ratio, 3.56 [95% confidence interval, 1.06–11.91]; P = .04). Eighty-three percent of HBoV infections were detected in patients with pneumonia who were <5 years old. More patients with pneumonia associated with HBoV—respiratory syncytial virus (RSV) or human parainfluenza virus (HPIV) coinfections had wheezing than patients with RSV and HPIV infections alone (9 [53%] of 17 vs. 32 [23%] of 138]; P = .01). Conclusions. HBoV infection was epidemiologically associated with pneumonia among young children in rural Thailand, but infection and illness may be dependent on coinfection with other viruses. url: https://www.ncbi.nlm.nih.gov/pubmed/17330795/ doi: 10.1086/512163 id: cord-011718-hcyluzkx author: Gaglani, Manjusha title: Antibody Response to Influenza A(H1N1)pdm09 Among Healthcare Personnel Receiving Trivalent Inactivated Vaccine: Effect of Prior Monovalent Inactivated Vaccine date: 2014-06-01 words: 4772.0 sentences: 243.0 pages: flesch: 49.0 cache: ./cache/cord-011718-hcyluzkx.txt txt: ./txt/cord-011718-hcyluzkx.txt summary: For the 3 primary analyses, we examined HCP characteristics: demographics, health status, vaccination history, timing of serum sampling, site, proxies for influenza exposure, and HI titer preseason. We thus compared the proportion of HCP with HI ≥ 40 for preseason, post-TIV, and end-of-season serum samples by vaccination history. When compared with HCP included preseason (Table 1) , those post-TIV were more likely to be aged 50-65 years, have high-risk conditions, and receive 2009-2010 seasonal vaccines, and less likely to work in the emergency department. The proportion of HCP who had prior-season MIIV was similar among those providing preseason (42%) and end-of-season (43%) serum samples, but higher among those providing post-TIV sera (57%) ( Table 1 ). Among these 834 vaccinated HCP, history of receipt of MIIV was associated with lower HI GMTs for post-TIV and end-of-season regardless of preseason HI GMTs ( Figure 1 ). abstract: Background. Few data are available on the immunogenicity of repeated annual doses of influenza A(H1N1)pdm09-containing vaccines. Methods. We enrolled healthcare personnel (HCP) in direct patient care during the autumn of 2010 at 2 centers with voluntary immunization. We verified the receipt of A(H1N1)pdm09-containing monovalent inactivated influenza vaccine (MIIV) and 2010–2011 trivalent inactivated vaccine (TIV). We performed hemagglutination inhibition antibody (HI) assays on preseason, post-TIV, and end-of-season serum samples. We compared the proportion of HCPs with HI titer ≥40 against A(H1N1)pdm09 per receipt of prior-season MIIV, current-season TIV, both, or neither. Results. At preseason (n = 1417), HI ≥ 40 was significantly higher among those who received MIIV (34%) vs those who did not (14%) (adjusted relative risk [ARR], 3.26; 95% confidence interval [CI], 2.72–3.81). At post-TIV (n = 865), HI ≥ 40 was lower among HCP who received MIIV and TIV (66%) than among those receiving only TIV (85%) (ARR, 0.93 [95% CI, .84–.997]). At end-of-season (n = 1254), HI ≥ 40 was 40% among those who received both MIIV and TIV and 67% among those receiving only TIV (ARR, 0.76 [95% CI, .65–.88]), 52% among those who received MIIV only, and 12% among those receiving neither.

CONCLUSIONS: This study provides evidence that reinfections with the same endemic coronavirus are not atypical in a time window shorter than 1 year and that the genetic basis of innate immune response may be a greater determinant of infection severity than immune memory acquired after a previous infection. However, in Korea, as reported by the Korean Centers for Disease Control and Prevention, viable SARS-CoV-2 was not isolated in cell culture of respiratory samples from potentially reinfected individuals [5] ; thus, these subsequent positive results may have been due to inactive genetic material detected by molecular testing. abstract: BACKGROUND: Although the mechanisms of adaptive immunity to pandemic severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are still unknown, the immune response to the widespread endemic coronaviruses HKU1, 229E, NL63, and OC43 provide a useful reference for understanding repeat infection risk. METHODS: Here we used data from proactive sampling carried out in New York City from fall 2016 to spring 2018. We combined weekly nasal swab collection with self-reports of respiratory symptoms from 191 participants to investigate the profile of recurring infections with endemic coronaviruses. RESULTS: During the study, 12 individuals tested positive multiple times for the same coronavirus. We found no significant difference between the probability of testing positive at least once and the probability of a recurrence for the betacoronaviruses HKU1 and OC43 at 34 weeks after enrollment/first infection. We also found no significant association between repeat infections and symptom severity, but found strong association between symptom severity and belonging to the same family. CONCLUSIONS: This study provides evidence that reinfections with the same endemic coronavirus are not atypical in a time window shorter than 1 year and that the genetic basis of innate immune response may be a greater determinant of infection severity than immune memory acquired after a previous infection. url: https://www.ncbi.nlm.nih.gov/pubmed/32692346/ doi: 10.1093/infdis/jiaa392 id: cord-317232-qk72i0gv author: Gierer, Stefanie title: Inhibition of Proprotein Convertases Abrogates Processing of the Middle Eastern Respiratory Syndrome Coronavirus Spike Protein in Infected Cells but Does Not Reduce Viral Infectivity date: 2015-03-15 words: 4936.0 sentences: 216.0 pages: flesch: 46.0 cache: ./cache/cord-317232-qk72i0gv.txt txt: ./txt/cord-317232-qk72i0gv.txt summary: title: Inhibition of Proprotein Convertases Abrogates Processing of the Middle Eastern Respiratory Syndrome Coronavirus Spike Protein in Infected Cells but Does Not Reduce Viral Infectivity However, activation of viral glycoproteins, including activation of the S protein of certain strains of the coronavirus infectious bronchitis virus (IBV) [18] , may also proceed in the constitutive secretory pathway of infected cells and is often accomplished by furin and other proprotein convertases [19] [20] [21] [22] . Treatment of MERS-CoV-infected cells with a proprotein convertase inhibitor (PCI) abrogated S protein cleavage but did not alter viral infectivity, indicating that S protein processing in infected cells is dispensable for MERS-S activation. In sum, our results identify MERS-S as a substrate of proprotein convertases but indicate that the activity of these enzymes is dispensable for MERS-CoV spread in target cell lines and potentially also in the infected human host. abstract: Middle East respiratory syndrome coronavirus (MERS-CoV) infection is associated with a high case-fatality rate, and the potential pandemic spread of the virus is a public health concern. The spike protein of MERS-CoV (MERS-S) facilitates viral entry into host cells, which depends on activation of MERS-S by cellular proteases. Proteolytic activation of MERS-S during viral uptake into target cells has been demonstrated. However, it is unclear whether MERS-S is also cleaved during S protein synthesis in infected cells and whether cleavage is required for MERS-CoV infectivity. Here, we show that MERS-S is processed by proprotein convertases in MERS-S–transfected and MERS-CoV–infected cells and that several RXXR motifs located at the border between the surface and transmembrane subunit of MERS-S are required for efficient proteolysis. However, blockade of proprotein convertases did not impact MERS-S–dependent transduction of target cells expressing high amounts of the viral receptor, DPP4, and did not modulate MERS-CoV infectivity. These results show that MERS-S is a substrate for proprotein convertases and demonstrate that processing by these enzymes is dispensable for S protein activation. Efforts to inhibit MERS-CoV infection by targeting host cell proteases should therefore focus on enzymes that process MERS-S during viral uptake into target cells. url: https://www.ncbi.nlm.nih.gov/pubmed/25057042/ doi: 10.1093/infdis/jiu407 id: cord-262840-fhfxnr76 author: Gorse, Geoffrey J. title: Human Coronavirus and Acute Respiratory Illness in Older Adults with Chronic Obstructive Pulmonary Disease date: 2009-03-15 words: nan sentences: nan pages: flesch: nan cache: txt: summary: abstract: BackgroundThe clinical features and incidence of human coronavirus (HCoV) infections in chronically ill older adults need better definition MethodsHCoV infection was determined on the basis of a 4-fold increase in serum antibody and the detection of HCoV by reverse-transcription polymerase chain reaction.

[6] A similar outcome, "vaccine associated enhanced respiratory disease (VAERD)," was observed in infants, 4 -12 months of age, who were given formalininactivated respiratory syncytial virus (RSV) and a few months later infected by RSV. The biological behavior of some coronaviruses in non-human species together with evidence that human coronavirus antibodies enhanced infection of SARS or MERS CoVs in Fc receptor-bearing cells, in vitro, have led to speculations that ADE contributes to disease severity in humans. [11] It has been reported that high levels of SARS CoV-1 IgG antibodies circulated in severe SARS cases and that anti-S IgG neutralizing antibody (NAb) responses developed significantly faster after the onset of clinical symptoms in fatal compared with recovered cases leading some to attribute enhanced tissue damage to ADE. With others, we conclude that the differences in clinical, epidemiological and pathological features of SARS and DENV diseases suggest that iADE does not contribute to the severity of natural human coronavirus infections. abstract: Might COVID 19 vaccines sensitize humans to antibody dependent enhanced (ADE) breakthrough infections? This outcome is unlikely because coronavirus diseases in humans lack the clinical, epidemiological, biological or pathological attributes of ADE disease exemplified by the dengue viruses (DENV). In contrast to DENV, SARS and MERS CoVs predominantly infect respiratory epithelium, not macrophages. Severe disease centers on older persons with pre-existing conditions and not young infants or individuals with previous coronavirus infections.

We showed in this study that although rAd5 expressing S1 or CD40-targeted S1 were both capable of inducing significant levels of IgG and nAbs specific to MERS-CoV in immunized mice, incorporation of CD40L substantially enhances the immunogenicity of S1, as demonstrated by the effectiveness of a single immunization dose, which was sufficient to elicit stronger and robust immune responses compared to control groups, consistent with our previous reports [37, 38] . abstract: BACKGROUND: Infection control measures have played a major role in limiting human/camel-to-human transmission of Middle East respiratory syndrome coronavirus (MERS-CoV); however, development of effective and safe human or camel vaccines is warranted. METHODS: We extended and optimized our previous recombinant adenovirus 5 (rAd5)–based vaccine platform characterized by in vivo amplified and CD40-mediated specific responses to generate MERS-CoV S1 subunit-based vaccine. We generated rAd5 constructs expressing CD40-targeted S1 fusion protein (rAd5-S1/F/CD40L), untargeted S1 (rAd5-S1), and Green Fluorescent Protein (rAd5-GFP), and evaluated their efficacy and safety in human dipeptidyl peptidase 4 transgenic (hDPP4 Tg(+)) mice. RESULTS: Immunization of hDPP4 Tg(+) mice with a single dose of rAd5-S1/F/CD40L elicited as robust and significant specific immunoglobulin G and neutralizing antibodies as those induced with 2 doses of rAd5-S1. After MERS-CoV challenge, both vaccines conferred complete protection against morbidity and mortality, as evidenced by significantly undetectable/reduced pulmonary viral loads compared to the control group. However, rAd5-S1– but not rAd5-S1/F/CD40L–immunized mice exhibited marked pulmonary perivascular hemorrhage post–MERS-CoV challenge despite the observed protection. CONCLUSIONS: Incorporation of CD40L into rAd5-based MERS-CoV S1 vaccine targeting molecule and molecular adjuvants not only enhances immunogenicity and efficacy but also prevents inadvertent pulmonary pathology after viral challenge, thereby offering a promising strategy to enhance safety and potency of vaccines. url: https://doi.org/10.1093/infdis/jiz137 doi: 10.1093/infdis/jiz137 id: cord-275355-4izc5jxs author: Hayden, Frederick title: Transmission of Avian Influenza Viruses to and between Humans date: 2005-10-15 words: 2246.0 sentences: 104.0 pages: flesch: 37.0 cache: ./cache/cord-275355-4izc5jxs.txt txt: ./txt/cord-275355-4izc5jxs.txt summary: in this issue of the Journal of Infectious Diseases [1] , and the recent instances of cross-species transmission that caused human disease [2] raise fundamental questions regarding the routes of transmission of avian viruses to and between humans, possible differences in transmission patterns between human and avian influenza viruses, and implications for prevention in those occupationally exposed to infected animals and also in health care, household, and community settings.

We studied the occurrence and hospitalization rates of HCoV over 9 years. METHODS: Children from Sør-Trøndelag County, Norway, hospitalized with RTIs and asymptomatic controls, were prospectively enrolled from 2006 to 2015. Nasopharyngeal aspirates were analyzed with semiquantitative polymerase chain reaction (PCR) tests for HCoV subtypes OC43, 229E, NL63, and HKU1, and 13 other respiratory pathogens. RESULTS: HCoV was present in 9.1% (313/3458) of all RTI episodes: 46.6% OC43, 32.3% NL63, 16.0% HKU1, and 5.8% 229E. Hospitalization rates for HCoV-positive children with lower RTIs were 1.5 and 2.8 per 1000 <5 and <1 years of age, respectively. The detection rate among controls was 10.2% (38/373). Codetections occurred in 68.1% of the patients and 68.4% of the controls. In a logistic regression analysis, high HCoV genomic loads (cycle threshold <28 in PCR analysis) were associated with RTIs (odds ratio = 3.12, P = .016) adjusted for relevant factors. CONCLUSIONS: HCoVs occurred in 1 of 10 hospitalized children with RTIs and asymptomatic controls. A high HCoV genomic load was associated with RTI. HCoVs are associated with a substantial burden of RTIs in need of hospitalization. url: https://doi.org/10.1093/infdis/jiy646 doi: 10.1093/infdis/jiy646 id: cord-007180-pho3miid author: Heine, J. title: Enteric Lesions and Diarrhea in Gnotobiotic Calves Monoinfected with Cryptosporidium Species date: 1984-11-17 words: 3396.0 sentences: 216.0 pages: flesch: 47.0 cache: ./cache/cord-007180-pho3miid.txt txt: ./txt/cord-007180-pho3miid.txt summary: Clinically affected calves have atrophy of villi and hyperplasia of crypt epithelium (apparently as a result of the destruction of villous epithelium); those areas of the small intestine that are heavily infected with the parasite become inflamed [7, 9, 10] . On the other hand, if confirmed, the reported occurrence of diarrhea and intestinal lesions in gnotobiotic pigs infected with an inoculum treated in a manner that destroys infectious agents other than Cryptosporidium [18] provides strong evidence that the parasite can act as a primary enteropathogen in the absence of other enteric flora. Gnotobiotic calves inoculated with oocysts of Cryptosporidium that had been treated with potassium dichromate and peracetic acid became infected with Cryptosporidium and developed clinical signs and enteric lesions. abstract: The pathogenicity of Cryptosporidium species was studied by inoculation of two gnotobiotic calves with cryptosporidial oocysts that had been decontaminated by treatment with peracetic acid. Two control calves were inoculated with similar material from which the oocysts had been removed by filtration. Oocyst-inoculated animals shed Cryptosporidium in their feces and developed depression, weakness, anorexia, and diarrhea. At necropsy five days after inoculation, endogeneous stages of Cryptosporidium were found in association with epithelial cells throughout the small and large intestines of these animals. The parasites were most numerous in the lower small intestine. Atrophic villi, disordered and degenerate villous epithelium, and hyperplastic crypt epithelium were associated with infection in the small intestine. Control animals remained normal. Extraneous agents were not detected in any of the calves. The results indicate that Cryptosporidium can destroy intestinal epithelial cells and cause diarrhea in monoinfected gnotobiotic calves. url: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7109781/ doi: 10.1093/infdis/150.5.768 id: cord-297432-2edncbgn author: Helleberg, Marie title: Persistent COVID-19 in an Immunocompromised Patient Temporarily Responsive to Two Courses of Remdesivir Therapy date: 2020-07-23 words: 2390.0 sentences: 139.0 pages: flesch: 46.0 cache: ./cache/cord-297432-2edncbgn.txt txt: ./txt/cord-297432-2edncbgn.txt summary: A man in his fifties treated with chemoimmunotherapy for chronic lymphocytic leukemia experienced a 9-week course of COVID-19 with high fever and severe viral pneumonia.

Severe acute respiratory syndrome (SARS) is a newly recognized infectious disease that has recently emerged in East Asia and North America. Although the clinical features of acute infection have been well described, mildly symptomatic or asymptomatic infections have not been well characterized. Objective. To assess the spectrum of illness in health-care workers (HCWs). Methods. A prospective seroepidemiologic cohort study was conducted on 372 HCWs in a large teaching hospital in Singapore who were both exposed and not exposed to patients with SARS. Participating HCWs completed a questionnaire and provided paired serum samples, which were analyzed by 2 different laboratories blinded to clinical data, by use of an enzyme-linked immunosorbent assay based on a protocol developed by the Centers for Disease Control and Prevention and a dot-blot immunoassay, with confirmation by a viral neutralization assay. Results. A total of 21 patients with SARS were treated at our hospital. They were associated with transmission to 14 staff members, patients, and visitors in our hospital. Of the 372 HCWs participating in the present study, 8 were found to have positive antibodies to the SARS coronavirus in both samples by use of both test methods, and 6 had pneumonia and had been hospitalized for either probable or suspected SARS infection, whereas 2 had fever but did not have changes on chest radiographs. All seropositive HCWs had been exposed either directly or indirectly to patients with SARS. No asymptomatic, nonexposed staff members were found to be seropositive. There was a trend towards protection for HCWs who, while fully protected, had had contact with patients with SARS. Conclusions. Although the majority of cases of SARS are associated with pneumonia, a small number of mildly symptomatic individuals do seroconvert. HCWs who are exposed to patients with SARS can be infected with SARS, regardless of the intensity of exposure. This has implications for surveillance and infection control planning, in the event that SARS returns next winter. url: https://www.ncbi.nlm.nih.gov/pubmed/14767817/ doi: 10.1086/381558 id: cord-001764-njzyu4mv author: Hofmann-Winkler, Heike title: Comparative Analysis of Host Cell Entry of Ebola Virus From Sierra Leone, 2014, and Zaire, 1976 date: 2015-10-01 words: 4175.0 sentences: 202.0 pages: flesch: 49.0 cache: ./cache/cord-001764-njzyu4mv.txt txt: ./txt/cord-001764-njzyu4mv.txt summary: Here, we show that the GPs of the EBOVs circulating in 1976 and 2014 transduce the same spectrum of target cells, use the same cellular factors for host cell entry, and are comparably susceptible to blockade by antiviral interferon-induced transmembrane proteins and neutralizing antibody KZ52. However, EBOV-GP 2014 was less susceptible than EBOV-GP 1976 to blockade by a third inhibitor, CatL ( Figure 3B ), which inhibits catB and catL activity to similar extents [40] , suggesting subtle differences in the protease dependence of these GPs. HIV-derived particles rapidly lose infectivity when stored at room temperature [41] , and this loss might be due to inactivation of the viral envelope protein. Comparably Inhibited by IFITM Proteins and Neutralizing Antibody KZ52 IFITM proteins 1, 2, and 3 inhibit cellular entry of EBOV [42] and several other viral pathogens [42, 43] and might reduce EBOV amplification in the infected host, raising the question of whether viruses circulating in 2014 are less susceptible to IFITM protein inhibition than those responsible for the 1976 outbreak in Zaire. abstract: The ongoing Ebola virus (EBOV) disease (EVD) epidemic in Western Africa is the largest EVD outbreak recorded to date and requires the rapid development and deployment of antiviral measures. The viral glycoprotein (GP) facilitates host cell entry and, jointly with cellular interaction partners, constitutes a potential target for antiviral intervention. However, it is unknown whether the GPs of the currently and previously circulating EBOVs use the same mechanisms for cellular entry and are thus susceptible to inhibition by the same antivirals and cellular defenses. Here, we show that the GPs of the EBOVs circulating in 1976 and 2014 transduce the same spectrum of target cells, use the same cellular factors for host cell entry, and are comparably susceptible to blockade by antiviral interferon-induced transmembrane proteins and neutralizing antibody KZ52. Thus, the viruses responsible for the ongoing EVD epidemic should be fully susceptible to established antiviral strategies targeting GP and cellular entry factors. url: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4564534/ doi: 10.1093/infdis/jiv101 id: cord-351776-otx5qwyu author: Ibáñez-Samaniego, Luis title: Elevation of Liver Fibrosis Index FIB-4 Is Associated With Poor Clinical Outcomes in Patients With COVID-19 date: 2020-06-21 words: 3896.0 sentences: 189.0 pages: flesch: 44.0 cache: ./cache/cord-351776-otx5qwyu.txt txt: ./txt/cord-351776-otx5qwyu.txt summary: In this study, we evaluated the association between FIB-4, a liver fibrosis index, and the risk of progression to critical illness in middle-aged patients with COVID-19. To overcome this problem, we analyzed our data in different ways: (1) we retrieved available information on blood test done within 6 months before COVID-19 diagnosis in a relatively small number of patients (15% of the total series): at the time of COVID-19 diagnosis, AST and ALT increased significantly while platelets remained stable as compared with previous values; however, there were no significant changes in FIB-4 categories; (2) we evaluated specifically the prognostic value of isolated baseline AST: in contrast to previous reports, AST was not an independent predictor either at univariate level or when adjusted by other clinical and laboratory covariates; and (3) finally, we evaluated specifically the association between the elevation of AST (ie, AST above the upper limit of normality) and the need for MV, which identified that AST elevation was an independent risk factor. abstract: BACKGROUND: COVID-19 is a potentially severe disease caused by the recently described SARS-CoV-2. Whether liver fibrosis might be a relevant player in the natural history of COVID-19 is currently unknown. We aimed to evaluate the association between FIB-4 and the risk of progression to critical illness in middle-aged patients with COVID-19. METHODS: In this multicenter, retrospective study with prospective follow-up of 160 patients aged 35–65 years with COVID-19, FIB-4, clinical, and biochemical variables were collected at baseline. FIB-4 ≥2.67 defined patients with risk for advanced liver fibrosis. RESULTS: Risk for advanced fibrosis was estimated in 28.1% of patients. Patients with FIB-4 ≥2.67 more frequently required mechanical ventilation (37.8% vs 18.3%; P = .009). In multivariate analysis, FIB-4 ≥2.67 (odds ratio [OR], 3.41; 95% confidence interval [CI], 1.30–8.92), cardiovascular risk factors (OR, 5.05; 95% CI, 1.90–13.39), previous respiratory diseases (OR, 4.54; 95% CI, 1.36–15.10), and C-reactive protein (OR, 1.01; 95% CI, 1.01–1.02) increased significantly the risk of ICU admission. Bootstrap confirmed FIB-4 as an independent risk factor. CONCLUSIONS: In middle-aged patients with COVID-19, FIB-4 may have a prognostic role. The link between liver fibrosis and the natural history of COVID-19 should be evaluated in future studies. url: https://www.ncbi.nlm.nih.gov/pubmed/32563190/ doi: 10.1093/infdis/jiaa355 id: cord-007305-pkjfnhro author: Iosub, Silvia title: Leukonychia Partialis in Kawasaki Disease date: 1984-10-17 words: 1083.0 sentences: 68.0 pages: flesch: 57.0 cache: ./cache/cord-007305-pkjfnhro.txt txt: ./txt/cord-007305-pkjfnhro.txt summary: COLLEAGUES -Some areas in the northern part of the Israel desert (Negev) are known to be endemic for Borrelia recurrentis infection [1] (tick-borne relapsing fever).

The fecal excretion of torovirus in patients with gastroenteritis was compared with that in matched asymptomatic controls in a case-control study. Toroviruses were identified in 72 (35.0%) of 206 gastroenteritis cases compared with 30 (14.5%) of 206 controls (P < .001). Clinical features of torovirus gastroenteritis in 172 patients positive for torovirus were compared with those of 115 patients infected with rotavirus or astrovirus. Persons infected with torovirus were more frequently immunocompromised (43.0% vs. 15.7%) and nosocomially infected (57.6% vs. 31.3%).

Even though it is usually a mild and self-limiting disease, hMPV can potentially cause severe lower respiratory infections, especially in young children, the elderly, and immunocompromised patients [3] [4] [5] [12] [13] [14] . Several studies have reported outbreaks due to hMPV in long-term care facilities (LTCF) for the elderly and described the high incidence of pneumonia [3] [4] [5] [14] [15] [16] [17] . In conclusion, we report the clinical and radiological features of hMPV pneumonia in non-immunocompromised patients collected from 3 outbreaks in LTCF in Okinawa, Japan. An outbreak of severe respiratory tract infection due to human metapneumovirus in a long-term care facility for the elderly in Oregon abstract: BACKGROUND: Several studies have reported outbreaks due to human metapneumovirus (hMPV) in long-term care facilities (LTCF) for the elderly. However, most of these reports are epidemiological studies and do not investigate the clinical features of hMPV pneumonia. METHODS: Three independent outbreaks of hMPV occurred at separate LTCF for intellectually challenged and elderly residents. A retrospective evaluation of hMPV pneumonia and its clinical and radiological features was conducted using available medical records and data. RESULTS: In 105 hMPV infections, 49% of patients developed pneumonia. The median age of pneumonia cases was significantly higher than non-pneumonia cases (P < .001). Clinical manifestations of hMPV pneumonia included high fever, wheezing in 43%, and respiratory failure in 31% of patients. An elevated number of white blood cells as well as increased levels of C-reactive protein, creatine phosphokinase, and both aspartate and alanine transaminases was also observed among pneumonia cases. Evaluation of chest imaging revealed proximal bronchial wall thickenings radiating outward from the hilum in most patients. CONCLUSIONS: The aforementioned characteristics should be considered as representative of hMPV pneumonia. Patients presenting with these features should have laboratory testing performed for prompt diagnosis. url: https://www.ncbi.nlm.nih.gov/pubmed/29733351/ doi: 10.1093/infdis/jiy261 id: cord-309786-8zyf9e3k author: Karron, Ruth A title: Safety and Immunogenicity of the Respiratory Syncytial Virus Vaccine RSV/ΔNS2/Δ1313/I1314L in RSV-Seronegative Children date: 2019-10-12 words: 4868.0 sentences: 229.0 pages: flesch: 45.0 cache: ./cache/cord-309786-8zyf9e3k.txt txt: ./txt/cord-309786-8zyf9e3k.txt summary: RESULTS: In RSV-seronegative children, the 10(5) PFU dose was overattenuated, but the 10(6) PFU dose was well tolerated, infectious (RSV/ΔNS2/Δ1313/I1314L replication detected in 90% of vaccinees), and immunogenic (geometric mean serum RSV plaque-reduction neutralizing antibody titer, 1:64). b A >4 fold-rise in serum RSV neutralizing antibody was detected in a placebo recipient in the 10 5 PFU dose cohort, probably indicating infection with wild-type RSV between study days 28 and 56. b A >4 fold-rise in serum RSV neutralizing antibody was detected in a placebo recipient in the 10 5 PFU dose cohort, probably indicating infection with wild-type RSV between study days 28 and 56. Live respiratory syncytial virus (RSV) vaccine candidate containing stabilized temperature-sensitivity mutations is highly attenuated in RSV-seronegative infants and children abstract: BACKGROUND: Respiratory syncytial virus (RSV) is the leading global cause of severe pediatric acute respiratory tract illness, and a vaccine is needed. RSV/ΔNS2/Δ1313/I1314L contains 2 attenuating elements: (1) deletion of the interferon antagonist NS2 gene and (2) deletion of codon 1313 of the RSV polymerase gene and the stabilizing missense mutation I1314L. This live vaccine candidate was temperature-sensitive, genetically stable, replication restricted, and immunogenic in nonhuman primates. METHODS: A single intranasal dose of RSV/ΔNS2/Δ1313/I1314L was evaluated in a double-blind, placebo-controlled trial (vaccine-placebo ratio, 2:1) at 10(6) plaque-forming units (PFU) in 15 RSV-seropositive children and at 10(5) and 10(6) PFU in 21 and 30 RSV-seronegative children, respectively. RESULTS: In RSV-seronegative children, the 10(5) PFU dose was overattenuated, but the 10(6) PFU dose was well tolerated, infectious (RSV/ΔNS2/Δ1313/I1314L replication detected in 90% of vaccinees), and immunogenic (geometric mean serum RSV plaque-reduction neutralizing antibody titer, 1:64). After the RSV season, 9 of 20 vaccinees had increases in the RSV titer that were significantly greater than those in 8 of 10 placebo recipients (1:955 vs 1:69, respectively), indicating that the vaccine primed for anamnestic responses after natural RSV exposure. CONCLUSION: Rational design yielded a genetically stable candidate RSV vaccine that is attenuated yet immunogenic in RSV-seronegative children, warranting further evaluation.

However, the details from Esper et al.''s study-the seasonal distribution, the percentage of positive samples, the associated respiratory syndromes, and the numbers of infected children at various ages, for example-were heavily influenced by both the particular population that was investigated and the clinical setting, so it is essentially impossible to draw conclusions on the epidemiology, pathogenicity, and relative importance of HCoV-NH in relation to other respiratory viruses.

Given the diversity detected here, larger-scale studies will be necessary to determine whether particular substrains of viruses confer an elevated risk of asthma exacerbation. Each NatURI specimen was analyzed independently in a blinded manner by 3 distinct viral detection methods: Virochip analysis and culture isolation for 9 common respiratory pathogens (HRV; RSV; influenza viruses A and B; human parainfluenza viruses 1, 2, and 3; adenovirus; and human enterovirus) and PCR for HRV. This diversity indicates that future studies that seek to link a particular virus or set of viruses to a discrete clinical outcome, such as exacerbation of asthma symptoms, will need to include large numbers of subjects and use pan-viral detection methods (such as the Virochip) that can differentiate among such isolates. abstract: Background. Between 50% and 80% of asthma exacerbations are associated with viral respiratory tract infections (RTIs), yet the influence of viral pathogen diversity on asthma outcomes is poorly understood because of the limited scope and throughput of conventional viral detection methods. Methods. We investigated the capability of the Virochip, a DNA microarray—based viral detection platform, to characterize viral diversity in RTIs in adults with and without asthma. Results. The Virochip detected viruses in a higher proportion of samples (65%) than did culture isolation (17%) while exhibiting high concordance (98%) with and comparable sensitivity (97%) and specificity (98%) to pathogen-specific polymerase chain reaction. A similar spectrum of viruses was identified in the RTIs of each patient subgroup; however, unexpected diversity among human coronaviruses (HCoVs) and human rhinoviruses (HRVs) was revealed. All but one of the HCoVs corresponded to the newly recognized HCoV-NL63 and HCoV-HKU1 viruses, and >20 different serotypes of HRVs were detected, including a set of 5 divergent isolates that formed a distinct genetic subgroup. Conclusions. The Virochip can detect both known and novel variants of viral pathogens present in RTIs.

HAI antibody titers against the pandemic H1N1 2009 MX10 isolate were detected at day 7 in ferrets receiving the laboratory-produced matched vaccine pH1N1inact or the swine influenza vaccine FluSure, reaching titers 140 on day 7 or 10, respectively. Toward this end, we compared the antibody and cellular responses elicited by 2 seasonal vaccines (Fluviral and FluMist), the commercial swine vaccine FluSure, and a laboratory-produced matched inactivated whole-virus preparation. A curious observation is the more severe cases of disease and the higher mortality rate noted for animals vaccinated with FluMist, which correlated with slightly more infectious virus in the nasal washes of this group at day 3. abstract: Background. The emergence and global spread of the pandemic H1N1 2009 influenza virus have raised questions regarding the protective effect of available seasonal vaccines and the efficacy of a newly produced matched vaccine. Methods. Ferrets were immunized with the 2008–2009 formulations of commercially available live attenuated (FluMist; MedImmune) or split-inactivated (Fluviral; GlaxoSmithKline) vaccines, a commercial swine vaccine (FluSure; Pfizer), or a laboratory-produced matched inactivated whole-virus vaccine (A/Mexico/InDRE4487/2009). Adaptive immune responses were monitored, and the animals were challenged with A/Mexico/InDRE4487/2009 after 5 weeks. Results. Only animals that received the swine or matched vaccines developed detectable hemagglutination- inhibiting antibodies against the challenge virus, whereas a T cell response was exclusively detected in animals vaccinated with FluMist. After challenge, all animals had high levels of virus replication in the upper respiratory tract. However, preexisting anti—pandemic H1N1 2009 antibodies resulted in reduced clinical signs and improved survival. Surprisingly, FluMist was associated with a slight increase in mortality and greater lung damage, which correlated with early up-regulation of interleukin-10. Conclusions. The present study demonstrates that a single dose of matched inactivated vaccine confers partial protection against a pandemic H1N1 2009 virus, and it suggests that a higher dose or prime-boost regimen may be required. The consequences of mismatched immunity to influenza merit further investigation. url: https://www.ncbi.nlm.nih.gov/pubmed/20170374/ doi: 10.1086/651171 id: cord-345101-h0i5o0do author: Koo, Bon-Sang title: Transient lymphopenia and interstitial pneumonia with endotheliitis in SARS-CoV-2-infected macaques date: 2020-08-03 words: 1808.0 sentences: 123.0 pages: flesch: 55.0 cache: ./cache/cord-345101-h0i5o0do.txt txt: ./txt/cord-345101-h0i5o0do.txt summary: Using a reliable primate model is critical for developing therapeutic advances to treat humans infected with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). The absence of a reliable preclinical animal model that recapitulates patients with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection poses a major limitation to the development of improved diagnostics and therapeutics. Studies reported that SARS-CoV-2 developed no severe clinical signs, but pulmonary pneumonia in 50% of cynomolgus macaques, recapitulating mild symptoms in humans [6] . The viral RNA was highest in the upper respiratory swab samples and lung tissues at the earliest phase of infection, and the viral antigen was present in the lungs ( Figure 1C and D) , suggesting the predominant site of the virus. Using a high viral titre administered through combined routes, virus assays, and histopathological changes suggests that both cynomolgus and rhesus macaques are permissive to infection of SARS-CoV-2 and recapitulate COVID-19-like disease in human. abstract: Using a reliable primate model is critical for developing therapeutic advances to treat humans infected with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). Here, we exposed macaques to high titres of SARS-CoV-2 via combined transmission routes. We observed acute interstitial pneumonia with endotheliitis in the lungs of all infected macaques. All macaques had a significant loss of total lymphocytes during infection, which were restored over time. These data show that SARS-CoV-2 causes a coronavirus disease 2019 (COVID-19)-like disease in macaques.

In this study, we fully characterized the Dutch clinical isolate of APMV-1-like virus, determined its phylogenetic relationship to other APMV-1 strains, and correlated presence of this virus with lesions in tissues obtained from the patient at autopsy. Domestic pigeons were inoculated intratracheally with the Dutch clinical virus isolate to determine infectivity and transmissibility, clinical signs, and pathological changes (Supplementary Methods). This is consistent with the New York case, where evidence of PPMV-1 infection in feces and urine also suggested extrarespiratory Pigeon Paramyxovirus-Linked Pneumonia • JID 2018:218 (1 October) • 1041 Table 1 spread [11] . It is relevant for these PPMV-1 cases that the risk of 2 pigeon-associated diseases-chlamydiosis and cryptococcosis-was largely a function of the immune status of patients, rather than contact with infected birds [32, 33] . abstract: The characteristics and risk factors of pigeon paramyxovirus type 1 (PPMV-1) infection in humans are poorly known. We performed virological, pathological, and epidemiological analyses of a Dutch case, and compared the results with those of a US case. Both infections occurred in transplant patients under immunosuppressive therapy and caused fatal respiratory failure. Both virus isolates clustered with PPMV-1, which has pigeons and doves as reservoir. Experimentally inoculated pigeons became infected and transmitted the virus to naive pigeons. Both patients were likely infected by contact with infected pigeons or doves. Given the large populations of feral pigeons with PPMV-1 infection in cities, increasing urbanization, and a higher proportion of immunocompromised individuals, the risk of severe human PPMV-1 infections may increase. We recommend testing for avian paramyxovirus type 1, including PPMV-1, in respiratory disease cases where common respiratory pathogens cannot be identified. url: https://doi.org/10.1093/infdis/jiy036 doi: 10.1093/infdis/jiy036 id: cord-269383-1tyorrb0 author: Lai, Christopher K C title: Prospective study comparing deep-throat saliva with other respiratory tract specimens in the diagnosis of novel coronavirus disease (COVID-19) date: 2020-08-01 words: nan sentences: nan pages: flesch: nan cache: txt: summary: abstract: BACKGROUND: Self-collected specimens has been advocated to avoid infectious exposure to healthcare workers. Self-induced sputum in those with a productive cough, and saliva in those without a productive cough have been proposed, but sensitivity remains uncertain. METHODS: We performed a prospective study in two regional hospitals in Hong Kong RESULTS: We prospectively examined 563 serial samples collected during the virus shedding periods of 50 patients: 150 deep-throat saliva (DTS), 309 pooled-nasopharyngeal (NP) and throat swabs, and 104 sputum. DTS had the lowest overall RT-PCR positive rate (68.7% vs. 89.4% [sputum] and 80.9% [pooled NP and throat swabs]), and the lowest viral RNA concentration (mean log copy/mL 3.54 vs. 5.03 [sputum] and 4.63 [pooled NP and throat swabs]). Analyses with respect to time from symptom onset and severity also revealed similar results. Virus yield of DTS correlated with that of sputum (Pearson correlation index [95% CI]: 0.76 [0.62 – 0.86]). We estimated the overall false-negative rate of DTS could be 31.3%, and increased 2.7 times among patients without sputum. CONCLUSION: DTS produced the lowest viral RNA concentration and RT-PCR positive rate compared to conventional respiratory specimens in all phases of illness. Self-collect sputum should be the choice for patients with sputum. url: https://doi.org/10.1093/infdis/jiaa487 doi: 10.1093/infdis/jiaa487 id: cord-288485-m3g88fl2 author: Lam, Katherine W title: Continued In-Hospital Angiotensin-Converting Enzyme Inhibitor and Angiotensin II Receptor Blocker Use in Hypertensive COVID-19 Patients Is Associated With Positive Clinical Outcome date: 2020-07-23 words: 3717.0 sentences: 185.0 pages: flesch: 43.0 cache: ./cache/cord-288485-m3g88fl2.txt txt: ./txt/cord-288485-m3g88fl2.txt summary: title: Continued In-Hospital Angiotensin-Converting Enzyme Inhibitor and Angiotensin II Receptor Blocker Use in Hypertensive COVID-19 Patients Is Associated With Positive Clinical Outcome BACKGROUND: This study investigated continued and discontinued use of angiotensin-converting enzyme inhibitors (ACEi) or angiotensin II receptor blockers (ARB) during hospitalization of 614 hypertensive laboratory-confirmed COVID-19 patients. Because the widely used antihypertensive medications angiotensin-converting enzyme inhibitors (ACEi) and angiotensin II receptor blockers (ARB) may upregulate ACE2 receptors [7] [8] [9] , through which severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) enters the host cells [10] , concerns have been raised as to whether their use may result in increased morbidity and mortality [4, [11] [12] [13] . The goal of this study was to investigate the effects of in-hospital continuation and discontinuation of ACEi/ARBs on the clinical outcomes of hypertensive COVID-19 patients, controlling for newly developed hypotension or AKI during hospitalization. abstract: BACKGROUND: This study investigated continued and discontinued use of angiotensin-converting enzyme inhibitors (ACEi) or angiotensin II receptor blockers (ARB) during hospitalization of 614 hypertensive laboratory-confirmed COVID-19 patients. METHODS: Demographics, comorbidities, vital signs, laboratory data, and ACEi/ARB usage were analyzed. To account for confounders, patients were substratified by whether they developed hypotension and acute kidney injury (AKI) during the index hospitalization. RESULTS: Mortality (22% vs 17%, P > .05) and intensive care unit (ICU) admission (26% vs 12%, P > .05) rates were not significantly different between non-ACEi/ARB and ACEi/ARB groups. However, patients who continued ACEi/ARBs in the hospital had a markedly lower ICU admission rate (12% vs 26%; P = .001; odds ratio [OR] = 0.347; 95% confidence interval [CI], .187–.643) and mortality rate (6% vs 28%; P = .001; OR = 0.215; 95% CI, .101–.455) compared to patients who discontinued ACEi/ARB. The odds ratio for mortality remained significantly lower after accounting for development of hypotension or AKI. CONCLUSIONS: These findings suggest that continued ACEi/ARB use in hypertensive COVID-19 patients yields better clinical outcomes. url: https://doi.org/10.1093/infdis/jiaa447 doi: 10.1093/infdis/jiaa447 id: cord-266573-vfl08i2p author: Largent, Emily A title: Paying Participants in COVID-19 Trials date: 2020-05-29 words: 3636.0 sentences: 157.0 pages: flesch: 36.0 cache: ./cache/cord-266573-vfl08i2p.txt txt: ./txt/cord-266573-vfl08i2p.txt summary: Given increased risk of undue influence against pandemic background conditions, incentive payment should be avoided unless essential to recruitment and retention in important trials whose social value outweighs this risk. Given the pandemic''s devastating economic effects, as well as the fact that risks may be higher or more uncertain in COVID-19 trials than in nonpandemic research, there is an increased likelihood of undue influence stemming from incentive payments. Rather, in light of pandemic circumstances-similar features of which may be replicated in other contexts, including research conducted in low-and middle-income countries or with participants whose nonresearch options are limited even in the absence of a pandemic-offers of compensation may raise ethical concerns akin to incentives [14] . Acknowledging this challenge, the best IRBs can do is to minimize the possibility of undue influence for trial participants on the whole by making it unlikely for research participation to constitute an objectively unreasonable choice for members of the target study population. abstract: Trials are in development and underway to examine potential interventions for treatment and prophylaxis of coronavirus disease 2019 (COVID-19). How should we think about offering payment to participants in these trials? Payment for research participation is ethically contentious even under ideal circumstances. Here, we review 3 functions of research payment—reimbursement, compensation, and incentive—and identify heightened and novel ethical concerns in the context of a global pandemic. We argue that COVID-19 trial participants should usually be offered reimbursement for research-related expenses, and compensation for their time and effort, as for other types of research under usual circumstances. Given increased risk of undue influence against pandemic background conditions, incentive payment should be avoided unless essential to recruitment and retention in important trials whose social value outweighs this risk. Where essential, however, incentives can be ethically permissible, so long as reasonable efforts are made to minimize the possibility of undue influence. url: https://doi.org/10.1093/infdis/jiaa284 doi: 10.1093/infdis/jiaa284 id: cord-010638-xjtapifg author: Law, Carmella L.

Because COVID-19 and influenza have similar means of transmission, it is hypothesized that NPIs targeting COVID-19 may also affect influenza transmission. In this study, the extent to which NPIs targeting COVID-19 have affected seasonal influenza transmission was explored. Indicators of seasonal influenza activity in the epidemiological year 2019/20 were compared with those in 2017/18 and 2018/19. Results show that the incidence rate of seasonal influenza reduced by 64% in 2019/20 (p&0.001).

By use of viral protein 2 (VP2) viruslike particles (VLPs), all 69 healthy adults who were studied were found to be positive (seropositive) for HBoV-specific IgG antibodies by ELISA. Using HBoV VLPs, we observed frequent VP2-specific humoral immune responses in healthy adults, whereas seronegative status was predominantly detected in young children (age, 2 years) [27, 37] . abstract: Background. Human bocavirus (HBoV) was recently described as a new member of the Parvoviridae family, and its possible association with respiratory illness in infants has been discussed. To date, HBoV genomes have been detected worldwide in respiratory tract samples obtained from children with pulmonary diseases, whereas only limited data on virus-specific immunity are available, mainly because of the lack of recombinant viral antigens. Methods. HBoV viruslike particles (VLPs) were produced in insect cells and characterized by electron microscopy and cesium chloride gradient centrifugation. HBoV viral protein 2 (VP2)-specific antibodies and CD4(+) T helper cell responses were analyzed by enzyme-linked immunsorbent assay and enzyme-linked immunospot assay. Results. VP2 capsid proteins of HBoV were produced in insect cells infected with a recombinant baculovirus, and the formation of icosahedral VLPs (diameter, 21–25 nm; sedimentation density, 1.33 g/cm(3)) was demonstrated. A significant increase in secretion of VP2-specific interferon-γ was detected in cultures of peripheral blood mononuclear cells obtained from 69 healthy adults found to be positive for HBoV-specific immunoglobulin G antibodies, compared with control stimulations. In parallel, T cell responses against identically expressed parvovirus B19 VP2 VLPs were frequently observed in the individuals studied, without there being obvious cross-reactions between HBoV and parvovirus B19. Conclusions. Data suggest the presence of HBoV-specific immune responses in adults and strongly support a high prevalence of HBoV among humans. url: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7109795/ doi: 10.1086/592985 id: cord-351571-gwtkrt5u author: Mackay, Ian M. title: Community-Wide, Contemporaneous Circulation of a Broad Spectrum of Human Rhinoviruses in Healthy Australian Preschool-Aged Children During a 12-Month Period date: 2013-05-01 words: 3374.0 sentences: 160.0 pages: flesch: 43.0 cache: ./cache/cord-351571-gwtkrt5u.txt txt: ./txt/cord-351571-gwtkrt5u.txt summary: Human rhinovirus (HRV) infections trigger exacerbations of asthma and chronic obstructive pulmonary disease and the majority of acute respiratory illnesses (ARIs), some of which meet criteria for influenza-like illness.

There are specific seasonal and annual variations in respiratory virus circulation and interactions [11] [12] [13] .

The recent assignment of 60 previously unknown HRV types to a third HRV species, Human rhinovirus C, raised questions about the prevalence of these picornavirus types in the community, the extent of HRV diversity at a single site, and whether the HRVs have an equally diverse clinical impact on their hosts. We quantified HRV diversity, and there was no clinical impact attributable to HRV species and genotypes among a community population of preschool-aged children with ARI who provided respiratory samples during 2003. All HRV species were represented among 138 children with ARI, and 74 distinct HRV types were cocirculating. Fever accompanied 32.8% of HRV-positive ARI cases. HRVs were less likely than DNA viruses to be codetected with another virus, suggesting virus interference at the community level, demonstrated by the inverse correlation between influenza virus detection and HRV detection. url: https://doi.org/10.1093/infdis/jis476 doi: 10.1093/infdis/jis476 id: cord-002333-90f9vr0a author: Madan, Anuradha title: Immunogenicity and Safety of an AS03-Adjuvanted H7N9 Pandemic Influenza Vaccine in a Randomized Trial in Healthy Adults date: 2016-12-01 words: 4250.0 sentences: 210.0 pages: flesch: 46.0 cache: ./cache/cord-002333-90f9vr0a.txt txt: ./txt/cord-002333-90f9vr0a.txt summary: The coprimary immunogenicity objective determined whether adjuvanted vaccines elicited an immune response against the vaccine-homologous virus, 21 days after the second vaccine dose per US and European licensure criteria in the per-protocol cohort (n = 389).

In a sub-analysis of the homologous immune response by age, the adjuvanted vaccine was immunogenic in both age groups, with SPRs ≥80.0% in participants 41-64 years of age, despite lower GMTs (Table 3 ). The results of this phase I/II randomized, placebo-controlled trial showed that 2 doses of the H7N9 AS03-adjuvanted vaccine elicited a robust immune response in healthy adults up to 64 years of age, with an acceptable safety profile. abstract: Background. Almost 700 cases of human infection with avian influenza A/H7N9 have been reported since 2013. Pandemic preparedness strategies include H7N9 vaccine development. Methods. We evaluated an inactivated H7N9 vaccine in an observer-blind study in healthy adults aged 18–64 years. Participants (420) were randomized to receive 1 of 4 AS03-adjuvanted vaccines (low or medium dose of hemagglutinin with AS03(A) or AS03(B)), one nonadjuvanted vaccine, or placebo. The coprimary immunogenicity objective determined whether adjuvanted vaccines elicited an immune response against the vaccine-homologous virus, 21 days after the second vaccine dose per US and European licensure criteria in the per-protocol cohort (n = 389). Results. All adjuvanted vaccines met regulatory acceptance criteria. In groups receiving adjuvanted formulations, seroconversion rates were ≥85.7%, seroprotection rates ≥91.1%, and geometric mean titers ≥92.9% versus 23.2%, 28.6%, and 17.2 for the nonadjuvanted vaccine. The AS03 adjuvant enhanced immune response at antigen-sparing doses. Injection site pain occurred more frequently with adjuvanted vaccines (in ≤98.3% of vaccinees) than with the nonadjuvanted vaccine (40.7%) or placebo (20.0%). None of the 20 serious adverse events reported were related to vaccination. Conclusions. Two doses of AS03-adjuvanted H7N9 vaccine were well tolerated and induced a robust antibody response at antigen-sparing doses in healthy adults. Clinical Trials Registration.

Four observational studies [24, 30, 37, 48] and 1 systematic review [22] reported data on severe cases of influenza A(H1N1)pdm09 infection treated with convalescent plasma (Table 3 and Supplementary Table 3 ). A case-comparison study at moderate risk of bias [30] reported no significant difference in length of hospital stay between treatment and control patients with severe pandemic influenza A (H1N1) infection who required ECMO ( Table 3) . abstract: Background. Administration of convalescent plasma, serum, or hyperimmune immunoglobulin may be of clinical benefit for treatment of severe acute respiratory infections (SARIs) of viral etiology. We conducted a systematic review and exploratory meta-analysis to assess the overall evidence. Methods. Healthcare databases and sources of grey literature were searched in July 2013. All records were screened against the protocol eligibility criteria, using a 3-stage process. Data extraction and risk of bias assessments were undertaken. Results. We identified 32 studies of SARS coronavirus infection and severe influenza. Narrative analyses revealed consistent evidence for a reduction in mortality, especially when convalescent plasma is administered early after symptom onset. Exploratory post hoc meta-analysis showed a statistically significant reduction in the pooled odds of mortality following treatment, compared with placebo or no therapy (odds ratio, 0.25; 95% confidence interval, .14–.45; I(2) = 0%). Studies were commonly of low or very low quality, lacked control groups, and at moderate or high risk of bias. Sources of clinical and methodological heterogeneity were identified. Conclusions.

In the current study, we examined a series of samples of different tissues, collected at autopsy, for the presence of HBoV and PARV4 DNA sequences and compared the frequencies of detection, viral loads, and genetic variability with those for B19. Samples from HIV-infected individuals who did not have AIDS (hereafter referred to as "pre-AIDS study subjects") and those with terminal AIDS at time of death were compared with corresponding samples from HIV-uninfected individuals, to investigate the relationship between viral load and immunosuppression and, thus, the role of the immune system in controlling virus replication. Among the HIV-infected study subjects, a similar difference was found in PARV4 viral loads in bone marrow versus lymphoid tissue (median values of 220 and 46 DNA copies/10 6 cells, respectively; ) (figure 1B). abstract: Background. PARV4 and human bocavirus (HBoV) are newly discovered human parvoviruses with poorly understood epidemiologies and disease associations. We investigated the frequencies of persistence, tissue distribution, and influence of immunosuppression on replication of these viruses. Methods. At autopsy, bone marrow, lymphoid tissue, and brain tissue from human immunodeficiency virus (HIV)—infected individuals with acquired immunodeficiency syndrome (AIDS) and those without AIDS and from HIV-uninfected individuals were screened for parvovirus B19, PARV4, and HBoV DNA by means of quantitative polymerase chain reaction analyses. Results. B19 DNA was detected both in HIV-infected study subjects (13 of 24) and in HIV-uninfected study subjects (8 of 8), whereas PARV4 DNA was detected only in HIV-infected study subjects (17 of 24). HBoV DNA was not detected in any study subjects. The degree of immunosuppression with HIV infection did not influence B19 or PARV4 viral loads. B19 or PARV4 plasma viremia was not detected in any study subjects (n = 76; viral load <25 DNA copies/mL). A significantly older age distribution was found for study subjects infected with B19 genotype 2, compared with those infected with B19 genotype 1. Two genotypes of PARV4 were detected; study subjects carrying prototype PARV4 (genotype 1) were younger (all born after 1958) than those infected with genotype 2 (PARV5; study subjects born between 1949 and 1956). Conclusions. Tight immune control of replication of B19 and PARV4 was retained despite profound immunosuppression. Recent genotype replacement of PARV4, combined with absent sequence diversity among genotype 1 sequences, suggests a recent, epidemic spread in the United Kingdom, potentially through transmission routes shared by HIV. url: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7109978/ doi: 10.1086/513280 id: cord-288072-42sx52tn author: Monto, Arnold S. title: The Tecumseh Study of Respiratory Illness.

As part of the study of respiratory infections in Tecumseh, Michigan, specimens of blood were collected on a regular basis from families under surveillance [10] . By testing of specimens collected in early 1967, a large-scale outbreak of infection with coronavirus 229E was detected [11] . All specimens of serum collected from members of 269 families were studied by CF and HAl for rise in titer of antibody to coronavirus OC43. The specimens with rises in CF or HAl titer both showed 66.7% agreement with the neutralization test. Neutralization tests confirmed the difference, and indicated that in the individual case during a period of prevalence of agents related to OC43, even if CF and HAl do not agree, it is likely that an infection with the agent actually did occur. abstract: Specimens of blood collected in Tecumseh, Michigan over a four-year period were studied for rise in antibody titer against coronavirus OC43. Peaks of infection were found in the winter and spring of 1966, 1968, and 1969; at other times, infections occurred sporadically. All age groups were involved, especially the very young. Rises in titer by CF and by HAI tests frequently did not occur together in the same individual. Agreement between the two tests was better in 1966 and 1969 than in the other years. A portion of the paired specimens showing rises in CF and/ or HAI titer was tested by neutralization. Rises in neutralizing antibody were usually found in pairs collected in 1966 and 1969 but not in those collected in 1967 and 1968.

In this study, we used an experimental approach designed to maximally detect antigen-specific CD4 + T cells by using cytokine enzyme-linked immunosorbent spot (ELISPOT) assays with pools of overlapping synthetic peptides as recall antigens to quantify responses to conserved and novel epitopes following vaccination of adults with monovalent inactivated A (H1N1)pdm09 vaccine. We conclude from this that expansion of CD4 + T cells rather than the baseline number of influenza virus-reactive cells correlates with and predicts the development of a neutralizing antibody response following A (H1N1)pdm09 vaccination, a result that is consistent with the idea that CD4 + T-cell help may limit the antibody response to pandemic influenza vaccines. abstract: Background. The ability of influenza vaccines to elicit CD4(+) T cells and the relationship between induction of CD4(+) T cells and vaccine-induced neutralizing antibody responses has been controversial. The emergence of swine-origin 2009 pandemic influenza A virus subtype H1N1 (A[H1N1]pdm09) provided a unique opportunity to examine responses to an influenza vaccine composed of both novel and previously encountered antigens and to probe the relationship between B-cell and T-cell responses to vaccination. Methods. We tracked CD4(+) T-cell and antibody responses of human subjects vaccinated with monovalent subunit A(H1N1)pdm09 vaccine. The specificity and magnitude of the CD4(+) T-cell response was evaluated using cytokine enzyme-linked immunosorbent spot assays in conjugation with peptide pools representing distinct influenza virus proteins. Results. Our studies revealed that vaccination induced readily detectable CD4(+) T cells specific for conserved portions of hemagglutinin (HA) and the internal viral proteins. Interestingly, expansion of HA-specific CD4(+) T cells was most tightly correlated with the antibody response. Conclusions. These results indicate that CD4(+) T-cell expansion may be a limiting factor in development of neutralizing antibody responses to pandemic influenza vaccines and suggest that approaches to facilitate CD4(+) T-cell recruitment may increase the neutralizing antibody produced in response to vaccines against novel influenza strains. url: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3532833/ doi: 10.1093/infdis/jis684 id: cord-001401-f29y8vh5 author: Nelson, Martha I. title: Multiyear Persistence of 2 Pandemic A/H1N1 Influenza Virus Lineages in West Africa date: 2014-07-01 words: 2511.0 sentences: 121.0 pages: flesch: 47.0 cache: ./cache/cord-001401-f29y8vh5.txt txt: ./txt/cord-001401-f29y8vh5.txt summary: Increased genetic sequencing of African A/H1N1 pandemic influenza viruses during 2009-2013 revealed multiyear persistence of 2 viral lineages within West Africa, raising questions about the roles of reduced air traffic and the asynchrony of seasonal influenza epidemics among West African countries in the evolution of independent lineages.

Of 2002 admissions, influenza A virus infection was diagnosed in 3.5% (71), influenza B virus infection, in 0.9% (19); and influenza C virus infection, in 0.8% (11 of 1404 tested). Four patients with influenza died. Among outpatients, 13 of 331 (3.9%) with acute respiratory infection and 1 of 196 without acute respiratory infection were influenza positive. The annual incidence of severe or very severe pneumonia, of influenza (any type), and of influenza A, was 1321, 60, and 43 cases per 100 000 <5 years of age, respectively. Peak occurrence was in quarters 3–4 each year, and approximately 50% of cases involved infants: temporal association with bacteremia was absent. Hypoxia was more frequent among pneumonia cases involving influenza (odds ratio, 1.78; 95% confidence interval, 1.04–1.96).

Here, we identified a total of 26 persistently asymptomatic patients with positive test results for SARS-CoV-2 nucleic acid to determine the clinical characteristics and asymptomatic carrier transmission of COVID-19 infection. A total of 26 hospitalized patients with a SARS-CoV-2 epidemiological history and positive SARS-CoV-2 nucleic acid test results were identified to analyze the epidemiological and clinical characteristics of COVID-19infected asymptomatic carriers. Discharge criteria for COVID-19 were as follows: 1) normal body temperature for more than 3 days; 2) significantly improved respiratory symptoms; 3) significantly improved chest radiography; and 4) two consecutive negative SARS-CoV-2 nucleic acid test results (sampling interval at least 1 day). abstract: BACKGROUND: We retrospectively analysed 26 persistently asymptomatic severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) carriers. METHODS: Epidemiological and clinical characteristics from the 26 asymptomatic patients with positive results for SARS-CoV-2 RNA testing were obtained. RESULTS: Twenty-two patients (84.6%) correlated with clustering occurrence. The median period from contact to diagnosis and the last positive nucleic acid test was 19 (8–24 days) and 21.5 days (10–36 days), respectively. The median period from diagnosis to negative nucleic acid test was significantly different between patients with normal or atypical chest computed tomography (CT) findings (n=16, 61.5%; 7.5 days [2–20 days]) and patients with typical ground-glass or patchy opacities on CT(n=10, 38.5%; 12.5 days[8–22 days]; P<0.01). Seven patients (70.0%) with initial positive nucleic acid test results had a negative result simultaneously with improved CT findings. Obvious improvement in CT findings was observed in three patients (30.0%) despite positive nucleic acid test results. CONCLUSION: In asymptomatic patients, changes in biochemical and inflammatory variables are small and changes on chest CT can occur. It is worth noting the long existence of SARS-CoV-2 in some asymptomatic patients and false-negative results need to be considered in SARS-CoV-2nucleic acid test. url: https://doi.org/10.1093/infdis/jiaa205 doi: 10.1093/infdis/jiaa205 id: cord-350749-ihkxouz8 author: Panda, Aditya K title: Plasmodium falciparum Infection May Protect a Population from Severe Acute Respiratory Syndrome Coronavirus 2 Infection date: 2020-07-29 words: 747.0 sentences: 51.0 pages: flesch: 39.0 cache: ./cache/cord-350749-ihkxouz8.txt txt: ./txt/cord-350749-ihkxouz8.txt summary: title: Plasmodium falciparum Infection May Protect a Population from Severe Acute Respiratory Syndrome Coronavirus 2 Infection The authors have suggested that prior exposure of children to coronavirus OC43 offers protection against severe COVID-19 phenotype by possible crossimmunity.

In the present article, we describe polymerase chain reaction (PCR) and sequencing studies done on 11 isolates from respiratory specimens from 10 Canadian patients with acute respiratory tract illness. Published nucleocapsid (N) and fusion (F) gene sequences of HMPV and avian pneumovirus were used to develop primers for detection and sequencing of HMPV at the Respiratory Virus Section (Centers for Disease Control and Prevention, Atlanta).

In this study, 11 isolates from 10 patients with respiratory disease from Quebec, Canada, were tested by a reverse-transcriptase polymerase chain reaction based on the fusion protein gene. Identified sequences were consistent with HMPV. The patients were 2 months to 87 years of age (median age, 58 years) and presented with acute respiratory tract illness during the winter season. Sequence studies of the nucleocapsid, fusion, and polymerase genes identified 2 main lineages of HMPV and cocirculation of both lineages during the same year.

Hypothesis testing allowed us to determine how likely it was that the observed patterns were due to chance, whereas model-based prediction allowed us to determine what trait or set of traits was the best predictor of a livestock virus''s ability to infect humans and to estimate the probability that a particular virus species would be able to jump host species, given knowledge of the traits of interest. To examine the magnitude and relative importance of the effects that the 3 molecular characteristics of interest have on the ability of the viral species in the database to infect humans, we developed a set of logistic regression models. abstract: Understanding viral factors that promote cross-species transmission is important for evaluating the risk of zoonotic emergence. Weconstructed a database of viruses of domestic artiodactyls and examined the correlation between traits linked in the literature to cross-species transmission and the ability of viruses to infect humans. Among these traits-genomic material, genome segmentation, and replication without nuclear entry-the last is the strongest predictor of cross-species transmission. This finding highlights nuclear entry as a barrier to transmission and suggests that the ability to complete replication in the cytoplasm may prove to be a useful indicator of the threat of cross-species transmission. url: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7110041/ doi: 10.1086/596510 id: cord-327673-3uem0e22 author: Qin, Gang title: Phosphoantigen-Expanded Human γδ T Cells Display Potent Cytotoxicity against Monocyte-Derived Macrophages Infected with Human and Avian Influenza Viruses date: 2009-09-01 words: nan sentences: nan pages: flesch: nan cache: txt: summary: abstract: BackgroundInfluenza virus is a cause of substantial annual morbidity and mortality worldwide. The potential emergence of a new pandemic strain (eg, avian influenza virus) is a major concern. Currently available vaccines and anti-influenza drugs have limited effectiveness for influenza virus infections, especially for new pandemic strains. Therefore, there is an acute need to develop alternative strategies for influenza therapy. γδ T cells have potent antiviral activities against different viruses, but no data are available concerning their antiviral activity against influenza viruses MethodsIn this study, we used virus-infected primary human monocyte-derived macrophages (MDMs) to examine the antiviral activity of phosphoantigen isopentenyl pyrophosphate (IPP)–expanded human Vγ9Vδ2 T cells against influenza viruses ResultsVγ9Vδ2 T cells were selectively activated and expanded by IPP from peripheral blood mononuclear cells. IPP-expanded Vγ9Vδ2 T cells efficiently killed MDMs infected with human (H1N1) or avian (H9N2 or H5N1) influenza virus and significantly inhibited viral replication. The cytotoxicity of Vγ9Vδ2 T cells against influenza virus–infected MDMs was dependent on NKG2D activation and was mediated by Fas–Fas ligand and perforin–granzyme B pathways ConclusionOur findings suggest a potentially novel therapeutic approach to seasonal, zoonotic avian, and pandemic influenza—the use of phosphoantigens to activate γδ T cells against influenza virus infections url: https://doi.org/10.1086/605413 doi: 10.1086/605413 id: cord-007234-hcpa8ej5 author: Renwick, Neil title: A Recently Identified Rhinovirus Genotype Is Associated with Severe Respiratory-Tract Infection in Children in Germany date: 2007-12-15 words: 2510.0 sentences: 135.0 pages: flesch: 40.0 cache: ./cache/cord-007234-hcpa8ej5.txt txt: ./txt/cord-007234-hcpa8ej5.txt summary: title: A Recently Identified Rhinovirus Genotype Is Associated with Severe Respiratory-Tract Infection in Children in Germany Here we report the investigation, by MassTag PCR, of pediatric respiratory-tract infections in Germany, studying 97 cases for which no pathogen was identified through routine laboratory evaluation.

In this study of samples collected, during a 3-year interval, from hospitalized children with severe undiagnosed respiratory infection, MassTag PCR allowed us to detect viral pathogens in 49 (51%) of 97 cases. Although we did not have samples to test for the presence of HRV in the lower respiratory tract, the high frequency at which HRV was identified as being the sole virus detected suggests a correlation between the agent and the observed LRTI symptoms. abstract: Acute respiratory infection is a significant cause of morbidity and mortality in children worldwide.

Prior receipt of a trivalent seasonal influenza vaccine (TIV) can affect hemagglutination inhibition (HI) antibody responses to pandemic influenza vaccines. We investigated the effect of TIV priming on humoral responses to AS03-adjuvanted and nonadjuvanted A(H1N1)pdm09 vaccines, the role of AS03 on cell-mediated immune (CMI) responses, and vaccine safety. Methods. Healthy adults (aged 19–40 years) were randomized 1:1:1:1 to receive TIV or saline followed 4 months later by 2 doses, 3 weeks apart, of adjuvanted or nonadjuvanted A(H1N1)pdm09 vaccine and followed up to study end (day 507). Pre- and postvaccination responses of HI and neutralizing antibody, CD4(+)/CD8(+) T cells, memory B cells, and plasmablasts were assessed. Results. Ninety-nine of the 133 participants enrolled completed the study. No vaccine-related serious adverse events were recorded. In TIV-primed participants, A(H1N1)pdm09-specific antibody and CD4(+) T-cell and memory B-cell responses to the pandemic vaccine tended to be diminished. Vaccine adjuvantation led to increased responses of vaccine-homologous and -heterologous HI and neutralizing antibodies and CD4(+) T cells, homologous memory B cells, and plasmablasts. Conclusions. In healthy adults, prior TIV administration decreased humoral and CMI responses to A(H1N1)pdm09 vaccine. Adjuvantation of A(H1N1)pdm09 antigen helped to overcome immune interference between the influenza vaccines. No safety concerns were observed. Registration.

Two different environmentally controlled rotating drum aerosol chambers, with volumes of 16-L and 208-L, were used in the present study to expose aerosols containing SARS-CoV-2 to controlled levels of temperature, relative humidity, and simulated sunlight. The present study examined the influence of simulated sunlight and relative humidity on the stability of SARS-CoV-2 in aerosols generated from virus suspended in either simulated saliva or culture medium at 20°C.

This study examined the effect of simulated sunlight, relative humidity, and suspension matrix on the stability of SARS-CoV-2 in aerosols. Both simulated sunlight and matrix significantly affected the decay rate of the virus. Relative humidity alone did not affect the decay rate; however, minor interactions between relative humidity and the other factors were observed. Decay rates in simulated saliva, under simulated sunlight levels representative of late winter/early fall and summer were 0.121±0.017 min(-1) (90% loss: 19 minutes) and 0.379±0.072 min(-1) (90% loss: 6 minutes), respectively. The mean decay rate without simulated sunlight across all relative humidity levels was 0.008±0.011 min(-1) (90% loss: 125 minutes). These results suggest that the potential for aerosol transmission of SARS-CoV-2 may be dependent on environmental conditions, particularly sunlight.

In contrast, the Egyptian fruit bat (EFB), Rousettus aegyptiacus, belongs to the same taxonomic family as Pteropus spp, Pteropodidae, and has been successfully used to model Marburg virus transmission [24, 25] and serological cross-reactivity after filovirus challenge [26] .

Nipah virus is capable of infecting a broad range of hosts including humans, pigs, ferrets, dogs, cats, hamsters, and at least 2 genera of bats. Little is known about the biology of NiV in the bat reservoir. In this study, we evaluate the potential for the Egyptian fruit bat (EFB), Rousettus aegyptiacus, to serve as a model organism for studying NiV in bats. Our data suggest that NiV does not efficiently replicate in EFBs in vivo. Furthermore, we show a lack of seroconversion against NiV glycoprotein and a lack of viral replication in primary and immortalized EFB-derived cell lines.

Because 1 patient had both the L386del variant and the wild-type variant in the same specimen, they raised the possibility that SARS-CoV exists as a quasi species, at least in some patients. Previous authors studying single-nucleotide variants from Beijing-area isolates in 2003 [2] and from the Singapore 2004 outbreak [3] have also found multiple viral sequences in the same sample that they attributed to quasi species. Although these 3 studies clearly establish the presence of a diversity of SARS-CoV genomes in individual patients, the issue of whether SARS-CoV quasi species exists remains open, particularly with respect to the 386-nt deletion.

Among all participants there was a statistically significant positive association between reporting a greater tendency to get sick and total self-reported symptom score (P < .0001 by the Tukey test); however, there was no significant association between reporting a greater tendency to get sick and actual detection of respiratory virus shedding (P = .10 by χ 2 analysis). The best-fit logistic regression model supported an association between an increased likelihood of testing positive for respiratory virus infection and a higher total symptom score (P < .0001) and being Hispanic (P < .005). abstract: To determine rates of both symptomatic and asymptomatic infection among ambulatory adults, we collected nasopharyngeal swab specimens, demographic characteristics, and survey information from 1477 adult visitors to a New York City tourist attraction during April–July 2016. Multiplex polymerase chain reaction analysis was used to identify specimens positive for common respiratory viruses. A total of 7.2% of samples tested positive for respiratory viruses; among positive samples, 71.0% contained rhinovirus, and 21.5% contained coronavirus. Influenza virus, respiratory syncytial virus, and parainfluenza virus were also detected. Depending on symptomatologic definition, 57.7%–93.3% of positive samples were asymptomatic. These findings indicate that significant levels of asymptomatic respiratory viral shedding exist during summer among the ambulatory adult population. url: https://doi.org/10.1093/infdis/jix685 doi: 10.1093/infdis/jix685 id: cord-333429-bq7kfpby author: Shi, Ding title: Clinical characteristics and factors associated with long-term viral excretion in patients with SARS-CoV-2 infection: a single center 28-day study date: 2020-07-02 words: 3513.0 sentences: 251.0 pages: flesch: 57.0 cache: ./cache/cord-333429-bq7kfpby.txt txt: ./txt/cord-333429-bq7kfpby.txt summary: title: Clinical characteristics and factors associated with long-term viral excretion in patients with SARS-CoV-2 infection: a single center 28-day study Male sex (HR, 0.58 [95% CI, 0.35-0.98]), immunoglobulin use (HR, 0.42 [95% CI, 0.24-0.76]), APACHE II score (HR, 0.89 [95% CI, 0.84-0.96]), and lymphocyte count (HR, 1.81 [95% CI, 1.05-3.1]) were independent factors associated with a prolonged duration of SARS-CoV-2 shedding.

In conclusion, we found that male sex, immunoglobulin use, APACHE II score, and lymphopenia were independent risk factors associated with the duration of SARS-CoV-2 RNA shedding, whereas ARV combination therapy and corticosteroid treatment were not. abstract: BACKGROUND: Despite the ongoing spread of COVID-19, knowledge about factors affecting prolonged viral excretion is limited. METHODS: In this study, we retrospectively collected data from 99 hospitalized patients with COVID-19 between January 19 and February 17 in Zhejiang Province, China. We classified them into two groups based on whether the virus test results eventually became negative. Cox proportional hazards regression was used to evaluate factors associated with SARS-CoV-2 shedding. RESULTS: Among 99 patients, 61 patients had SARS-CoV-2 clearance (virus-negative group), but 38 patients had sustained positive results (virus-positive group). The median duration of SARS-CoV-2 excretion was 15 days (IQR 12-19) among the virus-negative patients. The shedding time was significantly increased if fecal SARS-CoV-2 RNA test results was positive. Male sex (HR, 0.58 [95% CI, 0.35-0.98]), immunoglobulin use (HR, 0.42 [95% CI, 0.24-0.76]), APACHE II score (HR, 0.89 [95% CI, 0.84-0.96]), and lymphocyte count (HR, 1.81 [95% CI, 1.05-3.1]) were independent factors associated with a prolonged duration of SARS-CoV-2 shedding. Antiviral therapy and corticosteroid treatment were not independent factors. CONCLUSIONS: SARS-CoV-2 RNA clearance time was associated with sex, disease severity and lymphocyte function. The current antiviral protocol and low-to-moderate dosage of corticosteroid had little effect on the duration of viral excretion. url: https://doi.org/10.1093/infdis/jiaa388 doi: 10.1093/infdis/jiaa388 id: cord-300019-8vxqr3mc author: Shi, Ting title: The Etiological Role of Common Respiratory Viruses in Acute Respiratory Infections in Older Adults: A Systematic Review and Meta-analysis date: 2019-03-08 words: nan sentences: nan pages: flesch: nan cache: txt: summary: abstract: Acute respiratory tract infections (ARI) constitute a substantial disease burden in adults and elderly individuals. We aimed to identify all case-control studies investigating the potential role of respiratory viruses in the etiology of ARI in older adults aged ≥65 years. We conducted a systematic literature review (across 7 databases) of case-control studies published from 1996 to 2017 that investigated the viral profile of older adults with and those without ARI. We then computed a pooled odds ratio (OR) with a 95% confidence interval and virus-specific attributable fraction among the exposed (AFE) for 8 common viruses: respiratory syncytial virus (RSV), influenza virus (Flu), parainfluenza virus (PIV), human metapneumovirus (HMPV), adenovirus (AdV), rhinovirus (RV), bocavirus (BoV), and coronavirus (CoV). From the 16 studies included, there was strong evidence of possible causal attribution for RSV (OR, 8.5 [95% CI, 3.9–18.5]; AFE, 88%), Flu (OR, 8.3 [95% CI, 4.4–15.9]; AFE, 88%), PIV (OR, not available; AFE, approximately 100%), HMPV (OR, 9.8 [95% CI, 2.3–41.0]; AFE, 90%), AdV (OR, not available; AFE, approximately 100%), RV (OR, 7.1 [95% CI, 3.7–13.6]; AFE, 86%) and CoV (OR, 2.8 [95% CI, 2.0–4.1]; AFE, 65%) in older adults presenting with ARI, compared with those without respiratory symptoms (ie, asymptomatic individuals) or healthy older adults. However, there was no significant difference in the detection of BoV in cases and controls. This review supports RSV, Flu, PIV, HMPV, AdV, RV, and CoV as important causes of ARI in older adults and provides quantitative estimates of the absolute proportion of virus-associated ARI cases to which a viral cause can be attributed. Disease burden estimates should take into account the appropriate AFE estimates (for older adults) that we report. url: https://www.ncbi.nlm.nih.gov/pubmed/30849176/ doi: 10.1093/infdis/jiy662 id: cord-315457-w1nx9g91 author: Siedner, Mark J title: Desperate times call for temperate measures: practicing infectious diseases during a novel pandemic date: 2020-04-21 words: 1025.0 sentences: 63.0 pages: flesch: 66.0 cache: ./cache/cord-315457-w1nx9g91.txt txt: ./txt/cord-315457-w1nx9g91.txt summary: authors: Siedner, Mark J; Gandhi, Rajesh T; Kim, Arthur Y Of the thousands of peer-reviewed articles indexed in Pubmed, exactly one has reported the results of a randomized controlled trial; a single-centered study with approximately 200 COVID-19 infected individuals, investigating a drug developed for another virus, and resulting in a null finding.

All subjects received a single 30-µg dose of unadjuvanted, antigenically matched A/Shanghai2/2013(H7N9) pandemic inactivated influenza vaccine (pIIV) 12 weeks after their first dose of pLAIV. Vaccines for control of influenza viruses with pandemic potential are under development, and results of clinical trials have suggested that these vaccines will require the use of adjuvants and multiple doses to induce substantial serum antibody responses [4, 5] . If vaccine virus infection is defined as detection of the virus in culture or by real-time RT-PCR at any time after day 1 or as development of a ≥4-fold increased HAI antibody response, then approximately 20%-30% of subjects were infected after each dose of pLAIV. abstract: Background. We evaluated a candidate A/Anhui/2013(H7N9) pandemic live attenuated influenza vaccine (pLAIV) in healthy adults, and assessed the ability of 1 or 2 doses to induce immune memory. Methods. Healthy subjects in 2 age groups (18–49 years and 50–70 years) with undetectable hemagglutination-inhibiting (HAI) antibody to H7N9 were enrolled. Younger subjects received either 1 or 2 intranasal doses of 10(7.0) fluorescent focus units of A/Anhui/1/2013 pLAIV, while older subjects received a single dose. All subjects received a single 30-µg dose of unadjuvanted, antigenically matched A/Shanghai2/2013(H7N9) pandemic inactivated influenza vaccine (pIIV) 12 weeks after their first dose of pLAIV. Results. Both vaccines were well tolerated. Serum HAI antibody responses were detected in 0 of 32 younger subjects and 1 of 17 older subjects after 1 dose of pLAIV and in 2 of 16 younger subjects after a second dose. Strong serum antibody responses were detected after a single subsequent dose of pIIV that was broadly reactive against H7 influenza viruses. Conclusions. An A(H7N9) pLAIV candidate was safe in both age groups. Priming with pLAIV resulted in responses to subsequent pIIV that exceeded those seen in naive subjects in previous reports. The A(H7N9) pLAIV induces strong immune memory that can be demonstrated by exposure to subsequent antigenic challenge. Clinical Trials Registration.

To support the search for effective antiviral treatments, we evaluated the susceptibility of SARS CoV isolates (detailed studies were performed with the Tor2 isolate [Toronto, Canada]) to ribavirin and interferon (IFN)-a-2b in vitro. Our data indicate that ribavirin does not inhibit the virus at concentrations attainable in human serum but that IFN-a-2b may be useful and deserves further evaluation as a therapeutic agent. To quantify the effect of IFN-a-2b on the replication of the SARS CoV, Vero E6 cells were infected at an MOI of 0.001 and were incubated in the presence IFN-a-2b (0-5000 IU/mL), as described above. Whether combined therapy with IFN-a-2b and ribavirin would inhibit the replication of the SARS CoV in vitro has not yet been evaluated; the combination is more effective than either agent used alone for the treatment of HCV infection in humans. abstract: Current treatment schemes for severe acute respiratory syndrome (SARS) include broad-spectrum antibiotics, glucocorticoids, and ribavirin. We evaluated the susceptibility of the SARS-related coronavirus (SARS CoV) to ribavirin and interferon (IFN)-α in vitro by use of cytopathic effect, plaque assay, and immunoblot analysis. Ribavirin did not inhibit viral growth at concentrations attainable in human serum. In contrast, IFN-α showed an in vitro inhibitory effect starting at concentrations of 1000 IU/mL. In conclusion, ribavirin alone is unlikely to be beneficial in the prophylaxis or treatment of SARS CoV infections.

Severe fever with thrombocytopenia syndrome (SFTS) is caused by SFTS virus (SFTSV), a novel bunyavirus reported to be endemic in central and northeastern China. This article describes the first identified patient with SFTS and a retrospective study on SFTS in Japan. Methods. Virologic and pathologic examinations were performed on the patient's samples. Laboratory diagnosis of SFTS was made by isolation/genome amplification and/or the detection of anti-SFTSV immunoglobulin G antibody in sera. Physicians were alerted to the initial diagnosis and asked whether they had previously treated patients with symptoms similar to those of SFTS. Results. A female patient who died in 2012 received a diagnosis of SFTS. Ten additional patients with SFTS were then retrospectively identified. All patients were aged ≥50 years and lived in western Japan. Six cases were fatal. The ratio of males to females was 8:3. SFTSV was isolated from 8 patients. Phylogenetic analyses indicated that all of the Japanese SFTSV isolates formed a genotype independent to those from China. Most patients showed symptoms due to hemorrhage, possibly because of disseminated intravascular coagulation and/or hemophagocytosis. Conclusions.

Granulocyte-macrophage colony-stimulating factor was mostly undetectable in samples obtained during both symptomatic and asymptomatic periods. Interleukin-5 levels were low, but tended to increase in samples from symptomatic children. These data confirm that the eosinophil product MBP and the eosinophil chemoattractant chemokines RANTES and macrophage-inhibitory protein 1α are increased in upper respiratory viral infections associated with asthma exacerbations and suggest an important role for these chemokines in regulating eosinophil influx and activation.

Although test sensitivities were low (<40%) within the first 5 days after disease onset, immunoglobulin (Ig) M, IgA, and total antibody ELISAs increased in sensitivity to >80% between days 6 and 10 after symptom onset. The evaluated tests (including IgG and rapid tests) provided positive results in all patients at or after the 11th day after onset of disease. The specificities of the ELISAs were 83% (IgA), 98% (IgG), and 97% (IgM and total antibody). url: https://doi.org/10.1093/infdis/jiaa305 doi: 10.1093/infdis/jiaa305 id: cord-007264-r1w9a6gc author: Turner, Ronald B. title: Rhinovirus Infection of Human Embryonic Lung Fibroblasts Induces the Production of a Chemoattractant for Polymorphonuclear Leukocytes date: 1988-02-17 words: 2728.0 sentences: 154.0 pages: flesch: 50.0 cache: ./cache/cord-007264-r1w9a6gc.txt txt: ./txt/cord-007264-r1w9a6gc.txt summary: This study describes a chemoattractant for PMNLs that is elaborated by human embryonic lung fibroblast cells infected with rhinovirus.

This study describes a chemoattractant for PMNLs that is elaborated by human embryonic lung fibroblast cells infected with rhinovirus. Chemotaxis assays were done in a 48-well microchemotaxis chamber with normal adult PMNLs.

Elaboration of the chemoattractant was not a result of cell destruction and did not require the presence of infectious virus. This chemoattractant produced by human fibroblast cells may contribute to the influx of PMNLs into the nasal mucosa during rhinovirus infection.

Cryostat-cut sections obtained from a specific pathogen-free lamb that was heavily infected with Cryptosporidium derived originally from calves [14] were reacted with 12 convalescent-phase sera from red deer that were recovering from diarrhea. The results of the present communication demonstrate, on the basis of the excretion of typical oocysts in the feces and the attachment of typical stages of the organism to the brush borders of enterocytes, that these artificially reared red deer were infected with Cryptosporidium, There is thus strong circumstantial evidence to incriminate Cryptosporidium as the cause of diarrhea and mortality in the outbreak. The clinical disease was similar to that observed in field outbreaks of diarrhea associated with Cryptosporidium in calves [14] , lambs [9A] , and experimentally infected, specific pathogen-free lambs [13] . abstract: In an outbreak of diarrhea among 82 artificially reared red deer calves, 56 developed the disease and 20 subsequently died. During the outbreak 80% of diarrheal and 50% of apparently healthy calves excreted cryptosporidial oocysts in feces. The coincidence of infection with Cryptosporidium and clinical diarrhea suggested a causal relationship. Histologic examination of intestinal sections from a necropsied deer calf showed lesions consistent with field and experimental cryptosporidiosis in other species. The deer Cryptosporidium subclinically infected newborn mice; in indirect immunofluorescence tests, it could not be distinguished from a calf Cryptosporidium. url: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7109846/ doi: 10.1093/infdis/144.2.170 id: cord-341667-ayl71jpc author: Van Reeth, Kristien title: Bronchoalveolar Interferon-α, Tumor Necrosis Factor-α, Interleukin-1, and Inflammation during Acute Influenza in Pigs: A Possible Model for Humans? date: 1998-04-17 words: nan sentences: nan pages: flesch: nan cache: txt: summary: abstract: Biologically active interferon-α, tumor necrosis factor-α (TNF-α), and interleukin-1 (IL-1) were detected in bronchoalveolar lavage (BAL) fluids of 3-week-old cesarian-derived colostrum-deprived pigs inoculated with H1N1 influenza virus. Cytokine titers and lung virus titers were significantly higher 18–24 h after inoculation than at 48–72 h after inoculation in all 4 litters of pigs examined. All three cytokines were positively correlated with a 3- to 4-fold increase in BAL cell numbers (P < .036) and with a drastic neutrophil infiltration (24%–77% of BAL cells vs. 0–1.5% in controls) (P < .001). In addition, cytokine production coincided with the onset of general and respiratory symptoms of influenza and with the development of a necrotizing bronchopneumonia. This study is the first demonstration of TNF-α and IL-1 in BAL fluids of a natural influenza virus host.

METHODS: We conducted a one-stage individual participant data (IPD) meta-analysis exploring the association between NAI treatment and LoS in patients hospitalized with 2009 influenza A(H1N1) virus (A[H1N1]pdm09) infection. Using mixed-effects negative binomial regression and adjusting for the propensity to receive NAI, antibiotic, and corticosteroid treatment, we calculated incidence rate ratios (IRRs) and 95% confidence intervals (CIs). Patients with a LoS of <1 day and those who died while hospitalized were excluded. RESULTS: We analyzed data on 18 309 patients from 70 clinical centers. After adjustment, NAI treatment initiated at hospitalization was associated with a 19% reduction in the LoS among patients with clinically suspected or laboratory-confirmed influenza A(H1N1)pdm09 infection (IRR, 0.81; 95% CI, .78–.85), compared with later or no initiation of NAI treatment. Similar statistically significant associations were seen in all clinical subgroups. NAI treatment (at any time), compared with no NAI treatment, and NAI treatment initiated <2 days after symptom onset, compared with later or no initiation of NAI treatment, showed mixed patterns of association with the LoS. CONCLUSIONS: When patients hospitalized with influenza are treated with NAIs, treatment initiated on admission, regardless of time since symptom onset, is associated with a reduced LoS, compared with later or no initiation of treatment. url: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7313925/ doi: 10.1093/infdis/jiz152 id: cord-269654-473kac75 author: Voo, Teck Chuan title: Ethical Implementation of Immunity Passports During the COVID-19 Pandemic date: 2020-06-24 words: nan sentences: nan pages: flesch: nan cache: txt: summary: abstract: A number of countries are planning the use of “immunity passports” as a way to ease restrictive measures and allow infected and recovered people to return to work during the COVID-19 pandemic. This paper brings together key scientific uncertainties regarding the use of serological tests to assure immune status and a public health ethics perspective to inform key considerations in the ethical implementation of immunity passport policies. Ill-conceived policies have the potential to cause severe unintended harms that could result in greater inequity, the stigmatization of certain sectors of society, and heightened risks and unequal treatment of individuals due to erroneous test results. Immunity passports could, however, be used to achieve collective benefits and benefits for specific populations besides facilitating economic recovery. We conclude that sector-based policies that prioritize access to testing based on societal need are likely to be fairer and logistically more feasible, while minimizing stigma and reducing incentives for fraud. Clear guidelines need to be set out for which sectors of society should be prioritized for testing, and rigorous mechanisms should be in place to validate test results and identify cases of reinfection. url: https://www.ncbi.nlm.nih.gov/pubmed/32582943/ doi: 10.1093/infdis/jiaa352 id: cord-330645-46qaljq1 author: Waghmare, Alpana title: Reliability of self-sampling for accurate assessment of respiratory virus viral and immunologic kinetics date: 2020-07-25 words: 3294.0 sentences: 204.0 pages: flesch: 52.0 cache: ./cache/cord-330645-46qaljq1.txt txt: ./txt/cord-330645-46qaljq1.txt summary: Using longitudinal home-based self-sampling, we demonstrate nasal cytokine levels correlate and cluster according to immune cell of origin.

We aimed to clarify the characteristics and clinical significance of peripheral lymphocyte subset alteration in COVID-19. METHODS: The levels of peripheral lymphocyte subsets were measured by flow cytometry in 60 hospitalized COVID-19 patients before and after treatment, and their association with clinical characteristics and treatment efficacy was analyzed. RESULTS: Total lymphocytes, CD4(+) T cells, CD8(+) T cells, B cells, and natural killer (NK) cells decreased in COVID-19 patients, and severe cases had a lower level than mild cases. The subsets showed a significant association with inflammatory status in COVID-19, especially CD8(+) T cells and CD4(+)/CD8(+) ratio. After treatment, 37 patients (67%) showed clinical response, with an increase in CD8(+) T cells and B cells. No significant change in any subset was detected in nonresponsive cases. In multivariate analysis, posttreatment decrease in CD8(+) T cells and B cells and increase in CD4(+)/CD8(+) ratio were indicated as independent predictors of poor efficacy. CONCLUSIONS: Peripheral lymphocyte subset alteration was associated with clinical characteristics and treatment efficacy of COVID-19.

The present study reports several new observations: (1) proinflammatory cytokines, TNF-a, IL-1b, and IL-6, when upregulated by influenza A virus infection, induce trypsin expression in various organs and human endothelial cells; (2) the upregulated trypsin induces [Ca 2+ ] i mobilization via activation of the PAR-2, followed by loss of zonula occludens-1 and vascular hyperpermeability; (3) inhibitors of NF-kB and activator protein 1 effectively suppress the upregulation of proinflammatory cytokines and trypsin and improve the survival rates of infected mice. The present results allow us to propose a new mechanism of junctional permeability regulation: upregulated trypsin by influenza A virus and/or proinflammatory cytokines induces increase in [Ca 2+ ] i and loss of zonula occludens-1 in endothelial cells via PAR-2 signaling. abstract: Background. Severe influenza is characterized by cytokine storm and multiorgan failure with edema. The aim of this study was to define the impact of the cytokine storm on the pathogenesis of vascular hyperpermeability in severe influenza. Methods. Weanling mice were infected with influenza A WSN/33(H1N1) virus. The levels of proinflammatory cytokines, tumor necrosis factor (TNF) α, interleukin (IL) 6, IL-1β, and trypsin were analyzed in the lung, brain, heart, and cultured human umbilical vein endothelial cells. The effects of transcriptional inhibitors on cytokine and trypsin expressions and viral replication were determined. Results. Influenza A virus infection resulted in significant increases in TNF-α, IL-6, IL-1β, viral hemagglutininprocessing protease trypsin levels, and viral replication with vascular hyperpermeability in lung and brain in the first 6 days of infection. Trypsin upregulation was suppressed by transcriptional inhibition of cytokines in vivo and by anti-cytokine antibodies in endothelial cells. Calcium mobilization and loss of tight junction constituent, zonula occludens-1, associated with cytokine- and trypsin-induced endothelial hyperpermeability were inhibited by a protease-activated receptor-2 antagonist and a trypsin inhibitor.

The influenza virus-cytokine-protease cycle is one of the key mechanisms of vascular hyperpermeability in severe influenza. url: https://www.ncbi.nlm.nih.gov/pubmed/20731583/ doi: 10.1086/656044 id: cord-287210-sars5dmi author: Woo, Patrick C.

S protein could be cleaved by exogenous trypsin but not by coexpressed furin, suggesting that the protein is not normally processed during infection. Reactivity was evident by both flow cytometry and Western blot assays, but the pattern of reactivity varied according to assay and sequence of the antigen. The antibody response to SCoV S protein involves antibodies to both linear and conformational epitopes, with linear epitopes associated with the carboxyl domain and conformational epitopes associated with the amino terminal domain.

We first used the inhibitors of RLR and CLR signaling pathway to evaluate their potential contribution for mediating the proinflammatory response in MERS-CoV-infected macrophages. To assess the contribution of RLR or CLR pathway to induce proinflammatory response, we measured the expression levels of a series of key proinflammatory cytokines and/or chemokines in MERS-CoV-infected MDMs in the presence of these inhibitors ( Figure 1B ). Overall, the above results suggested that RLR and CLR signaling might be involved in viral recognition and trigger the proinflammatory response upon MERS-CoV infection in macrophages. Our results indicate that CLR and RLR signaling may be involved in mediating the immune activation in MERS-CoV-infected human macrophages. abstract: BACKGROUND: Human infection with Middle East respiratory syndrome coronavirus (MERS-CoV) poses an ongoing threat to public health worldwide. The studies of MERS patients with severe disease and experimentally infected animals showed that robust viral replication and intensive proinflammatory response in lung tissues contribute to high pathogenicity of MERS-CoV. We sought to identify pattern recognition receptor (PRR) signaling pathway(s) that mediates the inflammatory cascade in human macrophages upon MERS-CoV infection. METHODS: The potential signaling pathways were manipulated individually by pharmacological inhibition, small interfering ribonucleic acid (siRNA) depletion, and antibody blocking. The MERS-CoV-induced proinflammatory response was evaluated by measuring the expression levels of key cytokines and/or chemokines. Reverse transcription-quantitative polymerase chain reaction assay, flow cytometry analysis, and Western blotting were applied to evaluate the activation of related PRRs and engagement of adaptors. RESULTS: MERS-CoV replication significantly upregulated C-type lectin receptor (CLR) macrophage-inducible Ca(2+)-dependent lectin receptor (Mincle). The role of Mincle for MERS-CoV-triggered cytokine/chemokine induction was established based on the results of antibody blockage, siRNA depletion of Mincle and its adaptor spleen tyrosine kinase (Syk), and Syk pharmacological inhibition. The cytokine and/or chemokine induction was significantly attenuated by siRNA depletion of retinoic acid-inducible-I-like receptors (RLR) or adaptor, indicating that RLR signaling also contributed to MERS-CoV-induced proinflammatory response. CONCLUSIONS: The CLR and RLR pathways are activated and contribute to the proinflammatory response in MERS-CoV-infected macrophages. url: https://doi.org/10.1093/infdis/jiz483 doi: 10.1093/infdis/jiz483 id: cord-267015-mprsdi2e author: Zhu, Zhongyu title: Exceptionally Potent Cross-Reactive Neutralization of Nipah and Hendra Viruses by a Human Monoclonal Antibody date: 2008-03-15 words: 4460.0 sentences: 235.0 pages: flesch: 52.0 cache: ./cache/cord-267015-mprsdi2e.txt txt: ./txt/cord-267015-mprsdi2e.txt summary: One of these antibodies, m102, which exhibited the highest level of cross-reactive neutralization of both NiV and HeV G, was affinity maturated by light-chain shuffling combined with random mutagenesis of its heavy-chain variable domain and panning against sG(HeV). We have previously identified neutralizing human monoclonal antibodies against Nipah virus (NiV) and Hendra virus (HeV) by panning a large nonimmune antibody library against a soluble form of the HeV attachment-envelope glycoprotein G (sG HeV ). One of these antibodies, m102, which exhibited the highest level of cross-reactive neutralization of both NiV and HeV G, was affinity maturated by light-chain shuffling combined with random mutagenesis of its heavychain variable domain and panning against sG HeV . To demonstrate that m102.4 measured in plasma was biologically active, serum collected on days 1, 4, and 8 was evaluated using virus neutralization assays, as described above (data not shown). Receptor binding, fusion inhibition, and induction of cross-reactive neutralizing antibodies by a soluble G glycoprotein of Hendra virus abstract: We have previously identified neutralizing human monoclonal antibodies against Nipah virus (NiV) and Hendra virus (HeV) by panning a large nonimmune antibody library against a soluble form of the HeV attachment-envelope glycoprotein G (sG(HeV)). One of these antibodies, m102, which exhibited the highest level of cross-reactive neutralization of both NiV and HeV G, was affinity maturated by light-chain shuffling combined with random mutagenesis of its heavy-chain variable domain and panning against sG(HeV). One of the selected antibody Fab clones, m102.4, had affinity of binding to sG(HeV) that was equal to or higher than that of the other Fabs; it was converted to IgG1 and tested against infectious NiV and HeV. It exhibited exceptionally potent and cross-reactive inhibitory activity with 50% inhibitory concentrations below 0.04 and 0.6 μg/mL, respectively. The virus-neutralizing activity correlated with the binding affinity of the antibody to sG(HeV) and sG(NiV). m102.4 bound a soluble form of NiV G (sG(NiV)) better than it bound sG(HeV), and it neutralized NiV better than HeV, despite being originally selected against sG(HeV). These results suggest that m102.4 has potential as a therapeutic agent for the treatment of diseases caused by henipaviruses. It could be also used for prophylaxis and diagnosis, and as a research reagent url: https://www.ncbi.nlm.nih.gov/pubmed/18271743/ doi: 10.1086/528801 id: cord-276005-ifn88mjd author: da Silva Filho, Luiz Vicente Ribeiro Ferreira title: The Differential Clinical Impact of Human Coronavirus Species in Children With Cystic Fibrosis date: 2012-08-01 words: 2485.0 sentences: 113.0 pages: flesch: 42.0 cache: ./cache/cord-276005-ifn88mjd.txt txt: ./txt/cord-276005-ifn88mjd.txt summary: We investigated the clinical impact of human coronaviruses (HCoV) OC43, 229E, HKU1 and NL63 in pediatric patients with cystic fibrosis (CF) during routine and exacerbation visits. The proportion of cases with acute respiratory exacerbation among patients infected with different HCoV species was compared by χ 2 or Fisher exact tests. The identification of new species of HCoV [7, 8] and the emergence of SARS HCoV [6] highlighted the potential role of these viruses as causative agents of severe lower respiratory tract infections. However, most of the studies on the clinical impact of different HCoV species were only performed among children who were hospitalized for acute respiratory tract infections, with small sample sizes and short periods of sample collection [10] . New human coronavirus, HCoV-NL63, associated with severe lower respiratory tract disease in Australia abstract: We investigated the clinical impact of human coronaviruses (HCoV) OC43, 229E, HKU1 and NL63 in pediatric patients with cystic fibrosis (CF) during routine and exacerbation visits. A total of 408 nasopharyngeal aspirate samples were obtained from 103 patients over a 1-year period. Samples positive for HCoV were submitted for nucleotide sequencing to determine the species. Nineteen samples (4.65%) were positive for HCoV, of which 8 were positive for NL63, 6 for OC43, 4 for HKU1, and 1 for 229E. Identification of HCoV was not associated with an increased rate of respiratory exacerbations, but NL63-positive patients had higher exacerbation rates than patients who were positive for other HCoV species. url: https://www.ncbi.nlm.nih.gov/pubmed/22459737/ doi: 10.1093/infdis/jis274 id: cord-344271-5aynmdsk author: de Souza Luna, Luciano Kleber title: Spectrum of Viruses and Atypical Bacteria in Intercontinental Air Travelers with Symptoms of Acute Respiratory Infection date: 2007-03-01 words: 2304.0 sentences: 147.0 pages: flesch: 54.0 cache: ./cache/cord-344271-5aynmdsk.txt txt: ./txt/cord-344271-5aynmdsk.txt summary: title: Spectrum of Viruses and Atypical Bacteria in Intercontinental Air Travelers with Symptoms of Acute Respiratory Infection Using sensitive polymerase chain reactions, we studied the spectrum of atypical bacteria and respiratory viruses in travelers fulfilling the case definition of severe acute respiratory syndrome. These assays were used to determine a point prevalence of the full spectrum of respiratory viruses and atypical bacteria in SARS-compatible patients. Inf and PIV were clearly the most prevalent agents in flight patients, at 14.2% and 15.5%, respectively, without significant differences between age groups (1-way analysis of variance [ANOVA], 95% significance level). Baseline data on the prevalence of respiratory viruses and atypical bacteria after air travel are not currently available. It cannot be told whether the high prevalence and diversity of respiratory viruses seen in our study is specific to patients with recent intercontinental air travel. abstract: Respiratory infections after air travel are frequent, but epidemiological data are incomplete. Using sensitive polymerase chain reactions, we studied the spectrum of atypical bacteria and respiratory viruses in travelers fulfilling the case definition of severe acute respiratory syndrome. A pathogen was identified in 67 travelers (43.2%). Influenza and parainfluenza viruses were most prevalent, at 14.2% and 15.5%, respectively. Prevalences of adenoviruses, human metapneumovirus, coronaviruses, and rhinoviruses ranged between 2.6% and 4.8%. Human bocavirus, respiratory syncytial virus, and Legionella, Mycoplasma, and Chlamydophila species were absent or appeared at frequencies of <1%. To our knowledge, these are the first specific baseline data for the mentioned agents in the context of air travel. url: https://www.ncbi.nlm.nih.gov/pubmed/17262708/ doi: 10.1086/511432 id: cord-329392-fufattj8 author: den Hartog, Gerco title: SARS-CoV-2–Specific Antibody Detection for Seroepidemiology: A Multiplex Analysis Approach Accounting for Accurate Seroprevalence date: 2020-08-08 words: nan sentences: nan pages: flesch: nan cache: txt: summary: abstract: BACKGROUND: The COVID-19 pandemic necessitates better understanding of the kinetics of antibody production induced by infection with SARS-CoV-2. We aimed to develop a high-throughput multiplex assay to detect antibodies to SARS-CoV-2 to assess immunity to the virus in the general population. METHODS: Spike protein subunits S1 and receptor binding domain, and nucleoprotein were coupled to microspheres. Sera collected before emergence of SARS-CoV-2 (n = 224) and of non-SARS-CoV-2 influenza-like illness (n = 184), and laboratory-confirmed cases of SARS-CoV-2 infection (n = 115) with various severities of COVID-19 were tested for SARS-CoV-2–specific IgG concentrations. RESULTS: Our assay discriminated SARS-CoV-2–induced antibodies and those induced by other viruses. The assay specificity was 95.1%–99.0% with sensitivity 83.6%–95.7%. By merging the test results for all 3 antigens a specificity of 100% was achieved with a sensitivity of at least 90%. Hospitalized COVID-19 patients developed higher IgG concentrations and the rate of IgG production increased faster compared to nonhospitalized cases. CONCLUSIONS: The bead-based serological assay for quantitation of SARS-CoV-2–specific antibodies proved to be robust and can be conducted in many laboratories. We demonstrated that testing of antibodies against multiple antigens increases sensitivity and specificity compared to single-antigen–specific IgG determination. url: https://www.ncbi.nlm.nih.gov/pubmed/32766833/ doi: 10.1093/infdis/jiaa479 id: cord-261241-eqf6ame6 author: van Beek, Josine title: Influenza-like Illness Incidence Is Not Reduced by Influenza Vaccination in a Cohort of Older Adults, Despite Effectively Reducing Laboratory-Confirmed Influenza Virus Infections date: 2017-08-15 words: nan sentences: nan pages: flesch: nan cache: txt: summary: abstract: BACKGROUND: Data on the relative contribution of influenza virus and other respiratory pathogens to respiratory infections in community-dwelling older adults (≥60 years) are needed. METHODS: A prospective observational cohort study was performed in the Netherlands during 2 winters. Nasopharyngeal and oropharyngeal swabs were collected during influenza-like illness (ILI) episodes and from controls. Viruses and bacteria were identified by multiplex ligation–dependent probe amplification assay and conventional bacterial culture. RESULTS: The ILI incidence in the consecutive seasons was 7.2% and 11.6%, and influenza virus caused 18.9% and 34.2% of ILI episodes. Potential pathogen were detected in 80% of the ILI events with influenza virus, coronaviruses, rhinoviruses, human metapneumovirus, respiratory syncytial virus, parainfluenza viruses, and Haemophilus influenzae being the most common. Influenza vaccination reduced influenza virus infection by 73% (95% confidence interval [CI], 26%–90%) and 51% (95% CI, 7%–74%) in ILI patients. However, ILI incidence was similar between vaccinated (7.6% and 10.8%) and nonvaccinated (4.2% and 11.4%) participants in 2011–2012 and 2012–2013, respectively (P > .05). CONCLUSIONS: Influenza virus is a frequent pathogen in older adults with ILI. Vaccination reduces the number of influenza virus infections but not the overall number of ILI episodes: other pathogens fill the gap. We suggest the existence of a pool of individuals with high susceptibility to respiratory infections.

R. title: Frequent Detection of Human Coronaviruses in Clinical Specimens from Patients with Respiratory Tract Infection by Use of a Novel Real-Time Reverse-Transcriptase Polymerase Chain Reaction date: 2004-02-17 words: nan sentences: nan pages: flesch: nan cache: txt: summary: abstract: During the past years, human coronaviruses (HCoVs) have been increasingly identified as pathogens associated with more-severe respiratory tract infection (RTI). Diagnostic tests for HCoVs are not frequently used in the routine setting. It is likely that, as a result, the precise role that HCoVs play in RTIs is greatly underestimated. We describe a rapid, sensitive, and highly specific quantitative real-time reverse-transcriptase polymerase chain reaction (RT-PCR) for the detection of HCoV that can easily be implemented in the routine diagnostic setting. HCoV was detected in 28 (11%) of the 261 clinical specimens obtained from patients presenting with symptoms of RTI ranging from common cold to severe pneumonia. Only 1 (0.4%) of the 243 control specimens obtained from patients without symptoms of RTI showed the presence of HCoV. We conclude that HCoVs can be frequently detected in patients presenting with RTI. Real-time RT-PCR provides a tool for large-scale epidemiological studies to further clarify the role that coronavirus infection plays in RTI in humans. url: https://www.ncbi.nlm.nih.gov/pubmed/14767819/ doi: 10.1086/381207 ==== make-pages.sh questions [ERIC WAS HERE] ==== make-pages.sh search /data-disk/reader-compute/reader-cord/bin/make-pages.sh: line 77: /data-disk/reader-compute/reader-cord/tmp/search.htm: No such file or directory Traceback (most recent call last): File "/data-disk/reader-compute/reader-cord/bin/tsv2htm-search.py", line 51, in with open( TEMPLATE, 'r' ) as handle : htm = handle.read() FileNotFoundError: [Errno 2] No such file or directory: '/data-disk/reader-compute/reader-cord/tmp/search.htm' ==== make-pages.sh topic modeling corpus Zipping study carrel
