In patients where HBoV is the only virus detected, the clinical symptoms reported are similar to those occurring as a result of infection with respiratory syncytial virus (RSV) and human metapneumovirus (HMPV), including bronchiolitis, bronchitis, pneumonia and exacerbation of asthma. 20 Here, we report the findings of the first study investigating the prevalence, seasonality, clinical characteristics and the molecular epidemiology of HBoV in amongst an all-ages population of patients hospitalized for acute lower respiratory illness (ALRI) in Cambodia over 3 consecutive years. 5 In this study, ALRI patient samples were screened for HBoV infection using a highly sensitive multiplex PCR assay previously shown to have a lower limit of detection of 4 copies of HBoV DNA ⁄ ll of viral transport medium. doi = 10.1111/j.1750-2659.2012.00369.x id = cord-309497-3v0asfa7 author = Asner, Sandra title = Respiratory viral infections in institutions from late stage of the first and second waves of pandemic influenza A (H1N1) 2009, Ontario, Canada date = 2012-02-21 keywords = HRV; outbreak summary = ENT/HRV was frequently identified in LTCF outbreaks involving elderly residents, whereas in CSDs, A(H1N1)pdm09 was primarily detected. 1 Recent data reported by Public Health Ontario (PHO) indicated that pandemic influenza A (H1N1) 2009 [A(H1N1)pdm09] was a rare cause of LTCF respiratory outbreaks during the first period of wave I (April 20-June 12, 2009) of the 2009 pandemic. 3 We used surveillance data from the late stage of the first wave and the duration of the second wave periods (June 11-November 30, 2009) to ascertain the impact of A(H1N1)pdm09 and other respiratory viruses on different outbreak settings such as LTCFs and schools. We investigated all respiratory outbreaks in LTCFs and camps, schools, day cares (CSDs) tested at PHO laboratories from June 11 through November 30, 2009, in Ontario, Canada. 10, 11 From June 11 to November 30, 2009, we found that ENT ⁄ HRV was frequently identified in LTCF outbreaks involving elderly residents, whereas in outbreak settings involving children and younger adults, A(H1N1)pdm09 was primarily detected. doi = 10.1111/j.1750-2659.2012.00336.x id = cord-289358-4abypk6o author = Asner, Sandra A. title = Clinical severity of rhinovirus/enterovirus compared to other respiratory viruses in children date = 2014-05-07 keywords = ENT; HRV; RSV summary = Children with single HRV/ENT infections presented with significantly higher rates of underlying immunosuppressive conditions compared to those with RSV (37·9% versus 13·6%; P < 0·001), FLU (37·9% versus 22%; P = 0·018) or any other single viral infection (37·9% versus 22·5%; P = 0·024). Human rhinovirus/enterovirus (HRV/ENT) has been recently identified as the leading pathogen in acute asthma exacerbations, bronchiolitis, and viral pneumonia, although the clinical severity of respiratory illnesses attributed to HRV/ENT remains uncertain. The objective of this study was to compare the clinical characteristics and the severity of illness of HRV-/ENT-positive children to those positive for RSV A/B, FLU-A/ FLU-B, and other respiratory viruses by (i) using a large dataset with a broad pediatric inpatient and outpatient population; (ii) considering several clinical endpoints to assess disease severity, and (iii) conducting multivariable analysis to adjust for potential confounding variables. doi = 10.1111/irv.12255 id = cord-279716-kxfc4npg author = Blachere, Francoise M. title = Bioaerosol sampling for the detection of aerosolized influenza virus date = 2007-10-22 keywords = particle; viral summary = Background Influenza virus was used to characterize the efficacy of a cyclone‐based, two‐stage personal bioaerosol sampler for the collection and size fractionation of aerosolized viral particles. Results Based on qPCR results, we demonstrate that aerosolized viral particles were efficiently collected and separated according to aerodynamic size using the two‐stage bioaerosol sampler. In order to quantify the relative amount of viral particles or fungal spores collected at each stage of the bioaerosol sampler, qPCR was performed in parallel using either serial 10-fold dilutions of cDNA generated from a single dose of non-aerosolized FluMist Ò containing approximately 10 7 TCID 50 per influenza strain or genomic DNA isolated from 10 7 spores. In this study, by aerosolizing FluMist Ò , we demonstrate the recovery of aerosolized viral particles using the bioaerosol sampler and detection of influenza by qPCR. doi = 10.1111/j.1750-2659.2007.00020.x id = cord-002138-uywz5nqw author = Boëlle, Pierre‐Yves title = Transmission parameters of the A/H1N1 (2009) influenza virus pandemic: a review date = 2011-03-31 keywords = H1N1 summary = Methods We reviewed all studies presenting estimates of the serial interval or generation time and the reproduction number of the A/H1N1 (2009) virus infection. Accounting for under‐reporting in the early period of the pandemic and limiting variation because of the choice of the generation time interval, the reproduction number was between 1·2 and 2·3 with median 1·5. In the guidance document ''Global surveillance during an influenza pandemic'' released by the World Health Organization, three parameters were highlighted that should be documented quickly in this respect: the incubation period (time between infection and symptoms), the serial interval (time between symptoms onset in primary case and secondary case), and the reproduction ratio ⁄ number (average number of secondary cases per primary case). Indeed, before 2009, the two best documented values for the mean SI concerned seasonal influenza, with two estimates obtained in household-based studies: 2AE6 days (CI 95% 2AE1, 3AE0) 6 and 3AE6 days (CI 95% [2AE9, 4AE3]) 5 ; no information was available for past pandemics. doi = 10.1111/j.1750-2659.2011.00234.x id = cord-269644-94yrkzns author = Cousin, Mathias title = Rhinovirus‐associated pulmonary exacerbations show a lack of FEV (1) improvement in children with cystic fibrosis date = 2016-01-29 keywords = FEV summary = BACKGROUND: Respiratory viral infections lead to bronchial inflammation in patients with cystic fibrosis, especially during pulmonary exacerbations. The aim of this study was to determine the impact of viral‐associated pulmonary exacerbations in children with cystic fibrosis and failure to improve forced expiratory volume in 1 s (FEV (1)) after an appropriate treatment. CONCLUSIONS: Rhinovirus infection seems to play a role in the FEV (1) recovery after pulmonary exacerbation treatment in children with cystic fibrosis. The only risk factor significantly associated with failure to improve FEV 1 above 5% after PEx was viral respiratory infection at V2 and/or V3 (OR, 2Á04; 95% CI, 1Á57-2Á67) P = 0Á0088 and especially with rhinovirus infection: (OR, 12; 95% CI, 1Á29-111Á32, P = 0Á0288). The results of this pilot study show that rhinovirus infection during PEx is significantly associated with failure to improve FEV 1 after PEx treatment in children with CF.

The purpose of this study is to investigate the prevalence, seasonality and clinical characteristics of acute viral respiratory infections in hospitalized children in Shenzhen and to provide insights into etiologies of ARTIs in local infants and children. Most studies showed that RSV or HRV was the most prevalent viruses in children with viral respiratory tract infection. 9 In this study, due to the high detection rate and similar seasonality of RSV, HRV, IAV, PIV and HMPV, an overall spring-summer seasonality of viral respiratory infections in children was concluded. doi = 10.1111/irv.12257 id = cord-299790-vciposnk author = Ho, Zheng Jie Marc title = Clinical differences between respiratory viral and bacterial mono- and dual pathogen detected among Singapore military servicemen with febrile respiratory illness date = 2015-06-09 keywords = mono; pathogen summary = Although there were observed differences in mean proportions of body temperature, nasal symptoms, sore throat, body aches and joint pains between viral and bacterial mono-pathogens, there were few differences between distinct dual-pathogen pairs and their respective mono-pathogen counterparts. For instance, one study showed that 15.3% of ambulatory patients with influenza-like illness had two viruses detected, 6 and another found that in 28.2% of children with community-acquired pneumonia, the illness was due to mixed viral-bacterial infections. 7 Others also previously described respiratory viral 8, 9 and bacterial co-infections 10, 11 in various settings, although most focus on specific pathogen combinations, especially of the synergism between influenza and Streptococcus pneumoniae (S.

The weekly pH1N1 confirmed case and hospitalization data by onset week in Australia 8 fit the 1-wave Richards model (Table 6 and Figure 2E -F). doi = 10.1111/j.1750-2659.2010.00147.x id = cord-343050-1pfqgvie author = Huang, Qiu Sue title = Southern Hemisphere Influenza and Vaccine Effectiveness Research and Surveillance date = 2015-06-09 keywords = SHIVERS; influenza; respiratory; sari summary = The results during the first 2 years (2012-2013) provided scientific evidence to (a) support a change to NZ''s vaccination policy for young children due to high influenza hospitalizations in these children; (b) contribute to the revision of the World Health Organization''s case definition for severe acute respiratory illness for global influenza surveillance; and (c) contribute in part to vaccine strain selection using vaccine effectiveness assessment in the prevention of influenza-related consultations and hospitalizations.

Background We compared the efficacy of medical masks, N95 respirators (fit tested and non fit tested), in health care workers (HCWs). [16] [17] [18] The aim of this study was to determine the efficacy of medical masks compared to fit-tested and non-fit-tested N95 respirators in HCWs in the prevention of disease because of influenza and other respiratory viruses. For all outcomes, non-fit-tested N95 respirators had lower rates of infections compared to fit-tested N95s (for all N95 versus medical masks, the rates were 3AE9% versus 6AE7% for CRI, 0AE3% versus 0AE6% for ILI, 1AE4% versus 2AE6% for laboratory-confirmed virus and 0AE3% versus 1% for influenza) but these differences were not significant. doi = 10.1111/j.1750-2659.2011.00198.x id = cord-285425-3v1bid02 author = MacIntyre, Chandini Raina title = The efficacy of medical masks and respirators against respiratory infection in healthcare workers date = 2017-08-30 keywords = N95; mask summary = OBJECTIVE: We aimed to examine the efficacy of medical masks and respirators in protecting against respiratory infections using pooled data from two homogenous randomised control clinical trials (RCTs).

Background Surveillance for influenza viruses within live bird markets (LBMs) has been recognized as an effective tool for detecting circulating avian influenza viruses (AIVs). Efforts should be made to promote practices that could limit the maintenance and transmission of AIVs in LBMs. Influenza A viruses are zoonotic pathogens that infect a variety of domestic poultry such as chickens, turkeys, ducks, and geese. 2, 4, 5 Surveillance for influenza viruses within live bird markets (LBMs) has been recognized as an effective tool for detecting circulating influenza subtypes in the poultry population. 7, 8 Influenza viruses have also been detected in various environmental specimens collected in contaminated areas in LBMs including drinking water troughs, and surfaces in the delivery, holding and slaughter areas in markets. doi = 10.1111/j.1750-2659.2012.00365.x id = cord-304569-o39kl5k4 author = Nguyen-Van-Tam, Jonathan S title = From the Editor''s desk date = 2015-04-23 keywords = influenza; virus summary = If one shifts the focus away from influenza, the ongoing MERS-CoV outbreak in the Middle East, is also of substantial concern, because despite its likely introduction into humans via close contact with dromedary camels, 9 nosocomial transmission appears to be a central concern, 10,11 case-fatality is high, household transmission is also described, 12 and there are currently no vaccines or specific therapies available.

When the surveillance data of 2009 were fitted in the two detection models, alarms were produced on the occurrence of the first local case of influenza A (H1N1), outbreaks in schools and in general populations. Conclusions The results indicated the potential for using ILI and UP surveillance data as syndromic indicators to detect and provide an early warning for influenza epidemics. Two surveillance systems were established in Wuxi for influenza-like illness (ILI) and unexplained pneumonia (UP) after the severe acute respiratory syndrome (SARS) outbreak. To further evaluate the effectiveness of these surveillance systems in early warning of influenza epidemics, we monitored ILI data between 2004 and 2008 by both a control chart method and the Serfling method and tested goodness of fit using influenza A (H1N1) data of 2009. doi = 10.1111/j.1750-2659.2011.00248.x id = cord-002257-30s14h9j author = Ratnamohan, Vigneswary M. title = Phylogenetic analysis of human rhinoviruses collected over four successive years in Sydney, Australia date = 2016-08-09 keywords = HRV summary = Discordant branching was seen within HRV A group: two sequences clustering as A in the VP4/VP2 tree branched within the C/A subspecies in the 5′UTR tree, and one sequence showed identity to different HRV A strains in the two genes.

In this study, we report for the first time in Lao PDR the viral etiologies in patients hospitalized for ALRIs. We identified 186 respiratory viruses in 162 (55%) patients of all ages using 5 multiplex PCR/RT-PCR. Human respiratory syncytial virus is frequently defined as the predominant virus associated with hospitalizations for ALRI in children aged ≤5 years. Respiratory virus coinfections being frequent, 5, 19, 44 it demonstrates the usefulness of the multiplex RT-PCR approach, which allows the detection of the most important viruses in only few reactions while multiple infections are often undetected in viral culture or by direct immunofluorescence. doi = 10.1111/irv.12135 id = cord-336335-spap39b7 author = Silva, Denise R title = Respiratory viral infections and effects of meteorological parameters and air pollution in adults with respiratory symptoms admitted to the emergency room date = 2013-08-26 keywords = IFI; ILI; SARI; respiratory summary = doi = 10.1111/irv.12158 id = cord-307338-4nta9b6w author = Slomka, Marek J. title = Original Article: Real time reverse transcription (RRT)‐polymerase chain reaction (PCR) methods for detection of pandemic (H1N1) 2009 influenza virus and European swine influenza A virus infections in pigs date = 2010-08-17 keywords = PCR; RRT; table summary = Fifteen of these specimens (six swabs and nine tissues) were shown to be Avian influenza viruses, with highly pathogenic (HP) H5 and H7 isolates indicated positive for H1N1v by non-RRT PCR approaches (Table 3) , i.e. amplification of RNA extracted from the clinical specimen by conventional RT PCR using primers that had been designed specifically for the HA gene of current H1N1v isolates, available at: http://www.who.int/csr/resources/publications/swineflu/GenomePrimers_20090512.pdf Amplicons were electrophoresed in 2% agarose and stained with RedSafeÔ (iNtRON Biotechnology, Kyungki-Do, Korea) for visualisation, excised and purified from agarose using the QIAquick Ò Gel Extraction Kit (Qiagen, Crawley, UK).

A number of respiratory viruses including influenza viruses, respiratory syncytial virus (RSV), parainfluenza viruses, adenovirus and the recently described human metapneumovirus (hMPV) play an important role in acute respiratory tract infections (ARI) in children. In the South African setting, where the prevalence of HIV is high, all infant respiratory samples are routinely screened for CMV as in our setting this virus is a major cause of pneumonia in HIV-infected children. In conclusion these findings suggest that although HCoV-NL63 is circulating in the community it plays a minor role in severe respiratory tract infections in young children who require hospitalisation.

In this cross-sectional survey, we generated insights into individual-level exposures and behaviors among non-hospitalized adults with COVID-19 in Tennessee in the early days following national social distancing guidelines. Transmission of SARS-CoV-2 is likely facilitated through a pre-symptomatic or pauci-symptomatic shedding period in infected individuals, 2,3 which, along with limited early testing, could in part explain this common lack of a known case contact and highlights the need for robust testing infrastructure. However, a sizeable majority reported working regularly in the two weeks before illness with few able to telework, suggesting workplace-related exposures were an important early source of transmission in Tennessee.

The objective of the study was to determine the diagnostic agreement between Xpert ® Flu/RSV vs Allplex ™ RP1 for the detection of influenza A, influenza B, and RSV in the hospital emergency department (ED) or inpatient settings. While both assays were available to clinicians during the study period, the use of Xpert ® Flu/RSV was recommended to be used by the laboratory service for patients at high risk of influenza, where a result was required more urgently.

Data on the epidemiology and disease burden of influenza-related disease in South-East Asia (SEA) are emerging, and this, in turn, is shedding more light on the epidemiology of other viral and bacterial aetiologies of influenza-like illnesses (ILIs) in hospitalised adults and children in this region. The detection of influenza viruses and respiratory pathogens other than influenza viruses in specimens that were sent for routine influenza testing can provide valuable insights into the epidemiology of ILI across all age groups in three SEA countries over the same time period. 21 In this 1-year study, we used molecular techniques to detect viruses and atypical bacteria from samples collected from patients hospitalised with ILI. doi = 10.1111/irv.12326 id = cord-273861-sg7esn4p author = Yi, Lina title = A cluster of adenovirus type B55 infection in a neurosurgical inpatient department of a general hospital in Guangdong, China date = 2017-06-26 keywords = China; case summary = title: A cluster of adenovirus type B55 infection in a neurosurgical inpatient department of a general hospital in Guangdong, China All staff and patients in the involved neurosurgical department were surveyed for any symptoms of fever (≥38°C) and enlarged tonsils during the outbreak period. On June 30, 2016, one local Center for Disease Control and Prevention of Guangdong was informed that several staff members, including nurses and doctors working in a general hospital, fell ill with symptoms of a fever and sore throat.

Clinical disease and viral load in children infected with respiratory syncytial virus or human metapneumovirus Clinical characteristics and viral load of respiratory syncytial virus and human metapneumovirus in children hospitaled for acute lower respiratory tract infection High viral load of human bocavirus correlates with duration of wheezing in children with severe lower respiratory tract infection High prevalence of human bocavirus detected in young children with severe acute lower respiratory tract disease by use of a standard PCR protocol and a novel real-time PCR protocol Clinical significance of different virus load of human bocavirus in patients with lower respiratory tract infection doi = 10.1111/irv.12535 id = cord-337372-y43prnko author = bin‐Reza, Faisal title = The use of masks and respirators to prevent transmission of influenza: a systematic review of the scientific evidence date = 2011-12-21 keywords = SARS; mask; respirator summary = A limited effort was made to identify additional studies: reference lists of review articles were examined; the European Centre for Disease Prevention and Control''s (ECDC) Antimicrobial Resistance and Health Care Associated Infection Programme was consulted; and MEC''s and AN''s hardcopy literature files were hand-searched. [7] [8] [9] [10] [11] Two of these studies compared N95 respirators (designed to seal tightly to the wearer''s face and filter out very small particles or aerosols that may contain viruses) and surgical masks (used to block large droplets from coming into contact with the wearer''s mouth or nose) amongst healthcare workers; one trial found a lower rate of clinical respiratory illness associated with the use of non-fit-tested N95 respirators compared with medical masks, 6 whilst a non-inferiority trial found that masks and respirators offered similar protection to nurses against laboratory-confirmed influenza infection. doi = 10.1111/j.1750-2659.2011.00307.x id = cord-001521-l36f1gp7 author = nan title = Oral and Poster Manuscripts date = 2011-04-08 keywords = A(H1N1; CDC; China; ELISA; H1N1; H3N2; H5N1; H9N2; HAI; Health; Hong; ILI; Influenza; Kong; LAIV; MDCK; PB1-F2; PCR; RNA; TCID; USA; cell; figure; infection; ns1; pandemic; table; virus summary = The IC 50 values determined in functional NI assays provide valuable information for detection of resistant viruses, but should not be used to draw direct correlations with drug concentrations needed to inhibit virus replication in the infected human host, as clinical data to support such inferences are inadequate. • Standardized reagents and protocols • Choice of detection technology • Simple instrumentation requirements • High sensitivity for use with low virus concentrations • Compatibility with batch-mode processing and largescale assay throughput • Broad specificity of influenza detection • Flexibility in assay format • Additional NA assay applications -cell-based viral assays, screening for new NIs, detection of NA from other organisms Functional neuraminidase inhibition assays enable detection of any resistance mutation and are extremely important in conjunction with sequence-based screening assays for global monitoring of virus isolates for NI resistance mutations, including known and new mutations. Such new assays need to include methods to measure local antibodies and virus-specific lymphocytes, especially in the case of live attenuated influenza vaccines, because of their potential to induce such broad-based immune responses. doi = 10.1111/j.1750-2659.2011.00209.x id = cord-354151-psog34u3 author = van Asten, Liselotte title = Early occurrence of influenza A epidemics coincided with changes in occurrence of other respiratory virus infections date = 2015-12-11 keywords = early; influenza; virus summary = doi = 10.1111/irv.12348
