The Immediate Effect of COVID-19 Policies on Social-Distancing Behavior in the United States
Statewide stay-at-home policies had the strongest effect on reducing out-of-home mobility and increased the time people spent at home, according to a study employing difference-in-difference and event-study methodologies. Limits on restaurants and bars were the next highest ranked policy that increased presence at home. The other 4 policies assessed (limited stay-at-home orders, non-essential business closures,…
Assessing Mandatory Stay‐at‐Home and Business Closure Effects on the Spread of COVID‐19
A study evaluating the effects of mandatory stay-at-home and business closure policies found that implementing any non-pharmaceutical intervention (NPI) was associated with significant reductions in case growth in 9 of 10 study countries, including South Korea and Sweden which only implemented less restrictive NPIs. After subtracting the epidemic and less restrictive NPI effects, the study…

What Is the Value of Community Oximetry Monitoring in People with SARS-CoV-2 A Prospective Open-Label Clinical Study
[Pre-print, not peer reviewed A prospective study (n=41) in the UK found that at-home oximetry monitoring could be predictive of hospital admission. Monitoring identified 9 participants whose SpO2 dropped ≤94%, of which three dropped ≤92% and were admitted to the hospital. The mean maximum reduction in SpO2 was 2.8%, and the average time to maximum…
Strategies to Minimize SARS-CoV-2 Transmission in Classroom Settings Combined Impacts of Ventilation and Mask Effective Filtration Efficiency
[Pre-print, not peer reviewed] A laboratory experiment simulating a reduced occupancy classroom with aerosolized salt as a surrogate for potential SARS-CoV-2 airborne transmission suggests that good ventilation with up to 10 air exchanges per hour was not enough to achieve an infection probability of less than 1% following exposure for over an hour. However, use…

Staying Home, Distancing, and Face Masks: COVID-19 Prevention among U.S. Women in The COPE Study
Findings from the cross-sectional COPE Study (n=491) of women in the United States conducted from May to June 2020 suggest that women’s prevention behaviors for SARS-CoV-2 transmission are influenced by multilevel factors. Women who lived in urban environments, had minimal formal education, or had a household annual income of USD 30,000–50,000 were less likely to…

Can Face Masks Offer Protection from Airborne Sneeze and Cough Droplets in Close-up, Face-to-Face Human Interactions?—A Quantitative Study
With the exception of N95 masks, face coverings would not offer complete protection for a susceptible person exposed to coughing or sneezing of an infected person within 6 feet according to droplet flow visualization experiments. While no potentially virus-carrying particles were observed to leak through N95 masks when worn as protection, enough particles were found…

Digital proximity tracing app notifications lead to faster quarantine in non-household contacts results from the Zurich SARS-CoV-2 Cohort Study
[pre-print; not peer-reviewed] Users of the SwissCovid digital contract tracing app who were notified of a non-household close contact with a SARS-CoV-2 quarantined a median of 1 day earlier than close contacts who were manually traced. Among a population-based sample of adult SARS-CoV-2 index cases (n=393) and close contacts (n=261) identified through manual contact tracing…

Face Covering Adherence Is Positively Associated with Better Mental Health and Wellbeing a Longitudinal Analysis of the CovidLife Surveys
[Pre-print, not peer-reviewed] A longitudinal UK-wide survey found that individuals who wore face coverings “most of the time” or “always” had better mental health and wellbeing than those who did not, even after controlling for behavioral, social, and psychological factors. The odds of feeling anxious were 58% lower among individuals who “always” adhered to guidance…

Measures Implemented in the School Setting to Contain the COVID-19 Pandemic: A Scoping Review
A review of 42 studies that assessed measures to reopen or keep schools open during the COVID-19 pandemic found a heterogenous set of interventions implemented in school settings, including organizational (n=36) and structural or environmental measures (n=11) to reduce transmission, as well as surveillance and response measures to detect SARS-CoV-2 infections (n=19). Most studies assessed…

Drivers of Acceptance of COVID-19 Proximity Tracing Apps in Switzerland: A Panel Survey Analysis (Preprint)
Higher monthly household income, more frequent internet use, better adherence to mask use, and being a non-smoker were associated with reported uptake of digital proximity tracing apps in Sweden (n=1,511). In a randomly selected subsample (n=711) with more detailed information, higher levels of trust in government and health authorities were associated with app uptake. Most…
