A Predictive Modelling Framework for COVID-19 Transmission to Inform the Management of Mass Events
The approach ties together three main components: reliable modelling of the number of infectious cases at the time of the event, evaluation of the efficiency of pre-event screening and risk mitigation protocols, and modelling the transmission dynamics during the event. Expand
A highly efficient cloth facemask design
Evidence is presented that increasing the mouth-mask separation distance engenders an increase in the mask-fabric filtration efficiency toward expiratory aerosols emitted via vocalization, which is attributed to a decrease in the expIRatory jet velocity and expansion of the breath-mask contact area.

A solution scan of societal options to reduce transmission and spread of respiratory viruses: SARS-CoV-2 as a case study
This work used SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) as a case study to meet the immediate need to manage the COVID-19 pandemic and eventually transition to more normal societal conditions, and to catalog options for managing similar pandemics in the future. Expand

Asthma Management in the Era of the COVID-19 Pandemic
The reported effect of the COVID-19 pandemic on pediatric asthma including acute asthma admissions, does not appear to be significant, but this needs careful follow-up. Expand
COVID-19 Transmission due to Mass Mobility Before and After the Largest Festival in Bangladesh: An Epidemiologic Study
Mass mobility during Eid-ul-Adha influences the increased transmission of COVID-19 among the peripheral regions of Bangladesh from the central capital city Dhaka and will help policymakers plan and implement travel restrictions during festivals during the pandemic in LMICs. Expand
COVID-19 false dichotomies and a comprehensive review of the evidence regarding public health, COVID-19 symptomatology, SARS-CoV-2 transmission, mask wearing, and reinfection
This comprehensive narrative review deconstructs six common COVID-19 false dichotomies, addresses the evidence on these topics, identifies insights relevant to effective pandemic responses, and highlights knowledge gaps and uncertainties. Expand
COVID-19 mortality in Belgrade
Introduction: Mortality data are the most reliable indicators of the number of lives that a community has lost due to COVID-19 and represent the minimum data necessary for public healthExpand
COVID-19 prevention, air pollution and transportation patterns in the absence of a lockdown
Taking action to reduce the transmissibility of COVID-19 on metro cars, trains and buses, could help policymakers limit the substitution of personal motor vehicles for public transit, and mitigate increases in air pollution when lifting mobility restrictions. Expand


SARS-CoV-2 Transmission From People Without COVID-19 Symptoms
The findings of this study suggest that the identification and isolation of persons with symptomatic COVID-19 alone will not control the ongoing spread of SARS-CoV-2. Expand
Case-Control Study of Use of Personal Protective Measures and Risk for SARS-CoV 2 Infection, Thailand
The findings support consistent wearing of masks, handwashing, and social distancing to protect against COVID-19 and found the type of mask worn was not independently associated with infection and that contacts who always wore masks were more likely to practice social distanced. Expand
Children's emotion inferences from masked faces: Implications for social interactions during COVID-19.
While there may be some challenges for children incurred by others wearing masks, in combination with other contextual cues, masks are unlikely to dramatically impair children's social interactions in their everyday lives. Expand
Community Use Of Face Masks And COVID-19: Evidence From A Natural Experiment Of State Mandates In The US.
Evidence from a natural experiment on effects of state government mandates in the US for face mask use in public issued by 15 states plus DC between April 8 and May 15 suggests that requiring face maskUse in public might help in mitigating COVID-19 spread. Expand

Effectiveness of Adding a Mask Recommendation to Other Public Health Measures to Prevent SARS-CoV-2 Infection in Danish Mask Wearers
This randomized controlled trial investigates whether recommending surgical mask use when outside the home reduces wearers' risk for SARS-CoV-2 infection in a setting where masks were uncommon and not among recommended public health measures. Expand
Effectiveness of Face Masks in Preventing Airborne Transmission of SARS-CoV-2
It is found that cotton masks, surgical masks, and N95 masks all have a protective effect with respect to the transmission of infective droplets/aerosols of SARS-CoV-2 and that the protective efficiency was higher when masks were worn by a virus spreader. Expand
Efficacy of face masks, neck gaiters and face shields for reducing the expulsion of simulated cough-generated aerosols
The results suggest that face masks and neck gaiters are preferable to face shields as source control devices for cough aerosols. Expand
Reduction of secondary transmission of SARS-CoV-2 in households by face mask use, disinfection and social distancing: a cohort study in Beijing, China
The study confirms the highest risk of transmission prior to symptom onset, and provides the first evidence of the effectiveness of mask use, disinfection and social distancing in preventing COVID-19, and found evidence of faecal transmission. Expand
SARS-CoV-2 Infections and Serologic Responses from a Sample of U.S. Navy Service Members — USS Theodore Roosevelt, April 2020
The outbreak was characterized by widespread transmission with relatively mild symptoms and asymptomatic infection among this sample of mostly young, healthy adults with close, congregate exposures and the presence of neutralizing antibodies, which represent antibodies that inhibit SARS-CoV-2, among the majority of those with antibody responses is a promising indicator of at least short-term immunity.
