Summary of your 'study carrel' ============================== This is a summary of your Distant Reader 'study carrel'. The Distant Reader harvested & cached your content into a collection/corpus. It then applied sets of natural language processing and text mining against the collection. The results of this process was reduced to a database file -- a 'study carrel'. The study carrel can then be queried, thus bringing light specific characteristics for your collection. These characteristics can help you summarize the collection as well as enumerate things you might want to investigate more closely. This report is a terse narrative report, and when processing is complete you will be linked to a more complete narrative report.

In this paper we use a paradigm model to show that environmental transmission appears like direct transmission in the case where the pathogen persists little time in the environment. However, for obtaining results emerging from the first order expansion in the pathogen persistence time (e.g., the direct transmission model and its corresponding transmissibility formula) one may use the slow-fast dynamics formalism, a general technique of singular perturbation theory. In this work, we have shown using a paradigm model that direct transmission holds as an approximation for the environmental transmission mechanism in the case where the persistence time of the pathogen in the environment is short. doi = 10.1007/s00285-012-0520-2 id = cord-022237-qxya4cs3 author = Bryant, Everett title = Biology and Diseases of Birds date = 2013-11-17 keywords = Diagnosis; Differential; Epizootiology; Findings; Necropsy; Signs; Transmission; Treatment; bird; etiology summary = The bird fits into the overall taxonomic scheme as follows: Specific pathogen-free (SPF) fertile eggs, day-old chicks, or Kingdom, Animal; Phylum, Chordata; Class, Aves; Order, 27 started pullets are available for use in research.

Elucidating the physicochemical processes and surface science underlying the adsorption and transfer of virus between surfaces, as well as their inactivation, are important in understanding how the disease is transmitted, and in developing effective interception strategies. Three primary transmission routes have been found to contribute to the spread of respiratory viruses (e.g., SARS-CoV-1 and -2, measles, HCoV, rhinovirus, and influenza virus) ( Figure 1A ): 1) direct contact between individuals, 2) indirect contact via contaminated objects (fomites), 3) airborne transmission via droplets and aerosols. A study on SARS-CoV-2 infected patients in isolation rooms showed contamination of high-contact surfaces such as doorknobs and bedrails, as well as air outlet fans which indicated virus transfer from aerosols to a surface. doi = nan id = cord-277173-zdft23q8 author = Cauchemez, Simon title = Methods to infer transmission risk factors in complex outbreak data date = 2012-03-07 keywords = case; transmission summary = cases rather than the uninfected, but potentially susceptible bulk of the population, they can say little about the risk factors for infection or provide estimates of transmissibility in different contexts (e.g. households, schools or as a function of distance between a susceptible and an infected individual).

We present a relatively generic statistical model for the estimation of transmission risk factors, and discuss algorithms to estimate its parameters for different levels of missing data. For a directly transmitted disease, the first step to estimate transmission risk factors is usually to propose a model for transmission hazard l i!j ðtjQÞ from case i to subject j on day t, i.e. define l i!j ðtjQÞ as a function of the individual covariates z i (t) and z j (t) and a set of parameters Q. doi = 10.1098/rsif.2011.0379 id = cord-279520-zccd1mq5 author = Christian, Michael D. title = Possible SARS Coronavirus Transmission during Cardiopulmonary Resuscitation date = 2004-02-17 keywords = ICU; SARS; transmission summary = doi = 10.3201/eid1002.030700 id = cord-285960-1zuhilmu author = Conly, John title = Use of medical face masks versus particulate respirators as a component of personal protective equipment for health care workers in the context of the COVID-19 pandemic date = 2020-08-06 keywords = COVID-19; PPE; SARS; transmission summary = doi = 10.1186/s13756-020-00779-6 id = cord-308089-q2w9fb0i author = Ewald, Paul W. title = Evolution of virulence date = 2005-03-01 keywords = disease; pathogen; transmission; virulence summary = This new germ theory is emphasizing how environments and human activities influence the characteristics of infectious agents and the broader role of infection as a cause of chronic diseases. The association between vector-borne transmission and virulence explains why diseases such as malaria, yellow fever, dengue, sleeping sickness, and visceral leishmaniasis are so severe, whereas most of the respiratory-tract pathogens of humans are relatively benign. Evolutionary management of the virulence of vector-borne diseases requires interventions that elevate the immobilization of hosts more costly to the infecting pathogens. Although sexually transmitted pathogens are molded by natural selection to be benign over the short run, this long-term persistence within hosts raises the possibility of long-term damage, even though there is low probability of severe damage during any small period of time during the first years of infection. The theoretical framework for understanding the evolution of virulence of sexually transmitted pathogens provides clues about which infectious agents are the most likely causes of these illnesses. doi = 10.1016/s0891-5520(03)00099-0 id = cord-340357-gyvvcnuf author = Fallahi, Hamid Reza title = Being a front-line dentist during the Covid-19 pandemic: a literature review date = 2020-04-24 keywords = SARS; coronavirus; infection; transmission summary = doi = 10.1186/s40902-020-00256-5 id = cord-264994-j8iawzp8 author = Fitzpatrick, Meagan C. title = Modelling microbial infection to address global health challenges date = 2019-09-20 keywords = Ebola; HIV; datum; disease; model; transmission summary = doi = 10.1038/s41564-019-0565-8 id = cord-015884-mtpbzgr9 author = Haynes, Alice title = Current Practices for Infection Prevention in the Hospital Settings date = 2013-08-06 keywords = Precautions; patient; transmission summary = The CDC, in cooperation with the Healthcare Infection Control Practices Advisory Committee (HICPAC), established Standard Precautions to address the prevention of the spread of infectious agents in healthcare settings and are the result of combining the key components from Universal Precautions and Body Substance Isolation along with the understanding that all blood and body fl uids, except sweat, are potentially infectious, and inanimate objects are potentially contaminated with infectious agents, therefore are capable of being reservoirs in the chain of transmission of infectious agents [ 11 , 12 ] .

There have been myriads of hypotheses corroborating that certain threshold levels of humidity, temperature, sunlight, and ventilation will speed up the virus-laden droplet and aerosol transmission, aggravating the spread of the SARS-CoV disease (Morawska, 2006) . Nevertheless, the effectiveness of the use of masks for the control of SARS-CoV-2-laden aerosol transmission from an infected person to a susceptible host is uncertain and not fully conceivable. Researchers have speculated that both droplets and aerosols generated from non-violent and violent expirations of SARS-CoV-2-infected people may be responsible for the nonnosocomial and nosocomial transmission of COVID-19 disease. doi = 10.1016/j.envres.2020.109819 id = cord-299828-fb84rtmx author = Joseph, Maxwell B. title = Taming wildlife disease: bridging the gap between science and management date = 2013-04-16 keywords = WDM; disease; host; management; population; transmission summary = Despite the wealth of empirical WDM research, management outcomes can be difficult to predict because system-specific information is lacking for novel pathogens and many theoretical concepts in disease ecology (see Table 1 for a subset) have not been widely tested in the field, leading to uncertainty in their generality.

Recent events, including widespread media coverage of foodborne outbreaks and increased marketing of a variety of antibacterial products for personal hygiene and hard surface disinfection, have resulted in a resurgence of interest and public concern about hygiene and cleanliness in the home. 17 In a study to evaluate the survival of bacteria and enteric viruses during washing and drying as performed in U.S. homes, sterile cotton swabs were inoculated with Mycobacterium fortuitum, Salmonella typhimurium, Staphylococcus aureus, E. This body of research suggests that a product containing an ingredient with disinfectant properties, such as alcohol, bleach or a phenolic, may be indicated for home use if a household member is ill with an infectious disease or in other high-risk situations. doi = 10.1023/a:1016378226861 id = cord-347351-emdj66vj author = Kampf, Günter title = Potential sources, modes of transmission and effectiveness of prevention measures against SARS-CoV-2 date = 2020-09-18 keywords = CoV-2; RNA; SARS; covid-19; patient; transmission summary = doi = 10.1016/j.jhin.2020.09.022 id = cord-269505-7g8lio9l author = Keesing, Felicia title = Impacts of biodiversity on the emergence and transmission of infectious diseases date = 2010-12-01 keywords = disease; host; specie; transmission summary = For hantavirus pulmonary syndrome, a directly transmitted zoonotic disease, correlational and experimental studies have shown that a lower diversity of small mammals increases the prevalence of hantaviruses in their hosts, thereby increasing risk to humans (Box 2). Diversity has a similar effect for plant diseases, with species losses increasing the transmission of two fungal rust pathogens that infect perennial rye grass and other plant species 10 . This is because field studies like those on West Nile virus, hantaviruses and rye grass have typically not controlled for changes in host density that can result from changes in ''species richness'' (the number of species present in a community, which is a measure of taxonomic diversity). In sum, reducing biodiversity can increase disease transmission when the lost species are either not hosts for the pathogen or are suboptimal ones. In several case studies, the species most likely to be lost from ecological communities as diversity declines are those most likely to reduce pathogen transmission. doi = 10.1038/nature09575 id = cord-279443-2e4gz2bo author = Khan, Suliman title = Transmission of SARS-CoV-2, Required Developments in Research and Associated Public Health Concerns date = 2020-06-09 keywords = CoV-2; SARS; covid-19; transmission summary = doi = 10.3389/fmed.2020.00310 id = cord-299720-f0ny4ur5 author = Kim, Seung Woo title = Risk Factors for Transmission of Middle East Respiratory Syndrome Coronavirus Infection During the 2015 Outbreak in South Korea date = 2017-03-01 keywords = East; MERS; transmission summary = title: Risk Factors for Transmission of Middle East Respiratory Syndrome Coronavirus Infection During the 2015 Outbreak in South Korea Transmission heterogeneity was observed during the 2015 Korean outbreak of Middle East respiratory syndrome coronavirus (MERS-CoV) infection. Transmission heterogeneity was a significant characteristic of the 2015 South Korean outbreak of Middle East respiratory syndrome coronavirus (MERS-CoV) infection [1] . Epidemiological reports from the outbreak were evaluated to collect data regarding basic demographic characteristics, medical history, MERS-CoV exposure, symptoms and their onset date(s), sampling date(s), contact history, and post-exposure infection control. In the univariate analyses, transmission was associated with underlying respiratory disease, Ct value, interval from symptom onset to diagnosis, number of contacts, and pre-isolation hospitalization or ER visits. It appears that both host infectivity and the number of contacts influenced MERS-CoV transmission, whereas super-spreading events were mostly associated with a greater likelihood of encountering other people under diverse environmental conditions. doi = 10.1093/cid/ciw768 id = cord-320560-yn3bbkdh author = Kohanski, Michael A. title = Review of indoor aerosol generation, transport, and control in the context of COVID‐19 date = 2020-07-24 keywords = SARS; aerosol; transmission summary = [5] [6] [7] [8] [9] The lack of studies within the otorhinolaryngology field assessing the aerosol-generating potential of procedures involving mucosal surfaces pre-COVID-19 made it challenging to understand in an evidence-based fashion the potential risks of SARS-CoV-2 transmission associated with instrumentation of the upper airway; that is, whether these procedures may be infectious AGPs. At the early stages of the pandemic, based on the risks of exposure to high viral load mucosal surfaces, 10, 11 as well as on the lack of any immunity to SARS-CoV-2 and of any vaccines or effective treatments, an array of practice changes to protect health-care workers and patients were recommended and instituted for otorhinolaryngology procedures involving upper airway mucosal surfaces. doi = 10.1002/alr.22661 id = cord-307133-bm9z8gss author = Kong, Lingcai title = Modeling Heterogeneity in Direct Infectious Disease Transmission in a Compartmental Model date = 2016-02-24 keywords = NBD; model; transmission summary = Finally, we calibrated the model with the number of daily cases of severe acute respiratory syndrome (SARS) in Beijing in 2003, and the estimated parameters show that the control measures taken at that time were effective. A low level of heterogeneity results in dynamics similar to those predicted by the homogeneous-mixing model with a frequency-dependent transmission term, βSI N . The greatest difference is that at the overall level, the heterogeneity slows the transmission speed and decreases the peak sizes, which means milder disease outbreaks, because in the scenario with a high level of heterogeneity, only a small proportion of susceptible individuals have chances of coming into contact with infectious individuals and becoming infected, which results in a slower increase of the infected population. Our results show that, keeping other conditions identical, the higher is the level of heterogeneity in contact rates, the greater is the difference in the disease dynamics observed from those predicted using the homogeneous-mixing models. doi = 10.3390/ijerph13030253 id = cord-276916-j53i5xfs author = Kraemer, M.

Common spatiotemporal analyses of pathogen genomes focus on mapping and predicting virus lineage exchange among locations, with the underlying aim of reconstructing the pathways of disease introduction and spread, albeit at a coarse spatial resolution, and often retrospectively [2, 8, 33, 35, 37, 38] . In the recent yellow fever outbreak in southern Brazil, linking epidemiological, spatial and genomic data and techniques could provide insights into the transmission potential and risk of urban transmission [102] . doi = 10.1017/s0950268818002881 id = cord-336687-iw3bzy0m author = Kraemer, M. U. G. title = Big city, small world: density, contact rates, and transmission of dengue across Pakistan date = 2015-10-06 keywords = Lahore; dengue; model; transmission summary = Here, we fitted a mathematical model of dengue virus transmission to spatial time-series data from Pakistan and compared maximum-likelihood estimates of ''mixing parameters'' when disaggregating data across an urban–rural gradient. Accounting for differences in mobility by incorporating two fine-scale, density-dependent covariate layers eliminates differences in mixing but results in a doubling of the estimated transmission potential of the large urban district of Lahore. In no application of the TSIR model to date has the potential for variation in these parameters been assessed, leaving the extent to which inhomogeneity of mixing varies across space and time as an open question in the study of infectious disease dynamics. To assess the potential for spatial variation in the inhomogeneity of mixing as it pertains dengue transmission, we performed an analysis of district-level time series of dengue transmission in the Punjab province of Pakistan using a TSIR model with separate mixing parameters for urban and rural districts. doi = 10.1098/rsif.2015.0468 id = cord-263764-2ewz8ok4 author = Kutter, Jasmin S title = Transmission routes of respiratory viruses among humans date = 2018-01-17 keywords = SARS; respiratory; transmission; virus summary = We here present an overview of the available data from experimental and observational studies on the transmission routes of respiratory viruses between humans, identify knowledge gaps, and discuss how the available knowledge is currently implemented in isolation guidelines in health care settings. Our observations underscore the urgent need for new knowledge on respiratory virus transmission routes and the implementation of this knowledge in infection control guidelines to advance intervention strategies for currently circulating and newly emerging viruses and to improve public health. Increasing numbers of studies focused on the detection and quantification of influenza viruses contained in droplets and aerosols expelled into the air through breathing, sneezing and coughing of infected individuals The SARS outbreak was primarily linked to healthcare settings, with 49% of the cases linked to hospitals [71] , most probably caused by aerosol-generating procedures on severely ill patients [72, 73] . doi = 10.1016/j.coviro.2018.01.001 id = cord-297625-eby014gm author = L''Huillier, A.G. title = Survival of rhinoviruses on human fingers date = 2014-12-11 keywords = transmission summary = Our study confirms that rhinovirus infectiousness is related to the viral concentration in droplets and suggests that children represent the main transmission source, which occurs only rarely via adults. We conducted a series of experiments to assess the duration of human rhinovirus infectiousness duration on fingers, as well as the impact of viral concentration on survival rates. One hour after the deposit of disrupted droplets on the fingers of the six volunteers, infectious viruses could be detected by culture in all subjects contaminated with HC droplets (6/6), in four of the six volunteers with AC droplets, and none of the six volunteers with LC droplets, which confirmed the influence of concentration on survival (Fig. 1) . Our study showed that virus survival, and therefore infectiousness, was related to the viral concentration in droplets.

The authors state that the novel coronavirus is spread via aerosols and the faecal-oral route, in spite of a largely undeveloped evidence-base in support of these pathways. 2 Indeed, aerosol-generating procedures (AGPs) are implied in facilitating airborne transmission but limited evidence is available to support this for SARS-CoV-2. The authors imply confirmation of the faecal-oral route and reference a paper by Meng and colleagues however this seems to have been misinterpreted.

A. title = Characteristics associated with household transmission of SARS-CoV-2 in Ontario, Canada date = 2020-10-26 keywords = COVID-19; household; transmission summary = From adjusted logistic models, we observed increased odds of any household transmission with longer testing delays for the index case compared to 0-day (i.e., the individual was tested on the same day as their symptom onset) testing delays (ORs: 1-day delay=2·02, 2-day delay=1·96, 3-day delay=2·36, 4-day delay=2·64, ≥5-day delay=3·02) (Figure 3 , Supplementary Table S4 ). In this retrospective study of 26,152 confirmed cases of COVID-19 residing in 21,226 private households, we found that longer testing delays and male sex were associated with greater odds of household secondary transmission, while being a healthcare worker or linked to a known outbreak was associated with lower odds of household transmission. Adjusted odds ratios and 95% confidence intervals for the associations between index case delay metrics and odds of household transmission 269 cases were excluded from the testing delay models that had COVID-19 symptoms flagged in provincial reportable disease systems but were missing symptom onset date. doi = 10.1101/2020.10.22.20217802 id = cord-288303-88c6qsek author = Paul, S.

We experimented with available data of Covid-19 across multiple regions of USA and the model achieved 7.95% and 0.19% mean absolute percent error in terms of new infection cases in each locality and cumulative total infection cases across the country in a 10-day prediction period respectively.

Pathogen genomic data can capture within-host pathogen diversity (the product of effective population size in a generation and the average pathogen replication time [25, 26] ) and dynamics or provide information critical to understanding disease transmission such as evidence of new transmission pathways that cannot be inferred from epidemiological data alone [40, 41] . As molecular epidemiology and infectious disease transmission are areas in which network inference methods have been developed for bringing together multimodal data we use this review to investigate the foundational work in this specific field. In this section we briefly review multimodal integration methods for combining pathogen genomic data and epidemiological data in a single analysis, for inferring infection transmission trees and epidemic dynamic parameters. doi = 10.1016/j.jbi.2016.09.004 id = cord-347262-q88g1561 author = Schutzer‐Weissmann, J. title = Severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) infection risk during elective peri‐operative care: a narrative review date = 2020-07-11 keywords = COVID-19; SARS; respiratory; transmission summary = doi = 10.1111/anae.15221 id = cord-022103-4zk8i6qb author = Siegel, Jane D. title = Pediatric Healthcare Epidemiology date = 2017-07-18 keywords = CDC; HCP; Healthcare; IPC; Precautions; infection; patient; transmission summary = doi = 10.1016/b978-0-323-40181-4.00002-5 id = cord-276758-k2imddzr author = Siegel, Jane D. title = 2007 Guideline for Isolation Precautions: Preventing Transmission of Infectious Agents in Health Care Settings date = 2007-12-07 keywords = CDC; Control; MRSA; PPE; Precautions; SARS; Standard; Staphylococcus; States; United; base; care; health; infection; outbreak; patient; transmission summary = doi = 10.1016/j.ajic.2007.10.007 id = cord-003767-9xbu4hnq author = Slingenbergh, Jan title = Animal Virus Ecology and Evolution Are Shaped by the Virus Host-Body Infiltration and Colonization Pattern date = 2019-05-25 keywords = host; transmission; virus summary = The synthesis of the findings reveals a predictive virus evolution framework, based on the outerto inner-body changes in the interplay of host environment-transmission modes-organ system involvement-host cell infection cycle-virus genome.

For example, tighter control of the environment may reduce or prevent airborne transmission by: 1) isolating infectious patients in a single-bed, negative pressure isolation room [25] ; 2) controlling environmental relative humidity to reduce airborne influenza survival [59] ; 3) reducing exposure from aerosols produced by patients through coughing, sneezing or breathing with the use of personal protective equipment (wearing a mask) on the patient (to reduce source emission) and/or the healthcare worker (to reduce recipient exposure) [60] ; 4) carefully controlling the use and exposure to any respiratory assist devices (high-flow oxygen masks, nebulizers) by only allowing their use in designated, containment areas or rooms [61] . doi = 10.1186/s12879-019-3707-y id = cord-303651-fkdep6cp author = Thompson, Robin N. title = Key questions for modelling COVID-19 exit strategies date = 2020-08-12 keywords = COVID-19; SARS; datum; epidemic; estimate; model; transmission summary = doi = 10.1098/rspb.2020.1405 id = cord-334021-ex4z2b75 author = Tupper, P. title = COVID-19''s unfortunate events in schools: mitigating classroom clusters in the context of variable transmission date = 2020-10-22 keywords = covid-19; international; transmission summary = Early evidence indicated that schools were low risk and children were unlikely to be very infectious, but it is becoming clear that children and youth can acquire and transmit COVID-19 in school settings and that transmission clusters and outbreaks can be large.
