Excess Deaths and Hospital Admissions for COVID-19 Due to a Late Implementation of the Lockdown in Italy
Palladino et al. evaluated the effect of the national lockdown in Italy and compared ICU admission, general hospital admissions, and deaths to estimated numbers that may have resulted if the lockdown had started one week earlier. They conclude that an earlier implementation of the lockdown would have avoided about 60% of cases, 52% of non-ICU…
Acceptability of App-Based Contact Tracing for COVID-19: Cross-Country Survey Evidence
Altmann et al. measured support for digital contact tracing of COVID-19 infections using anonymous online surveys of 5,995 people in France, Germany, Italy, the UK, and the US. In spite of concerns about cyber-security and privacy and a lack of trust in governments, they found strong support (>68%) for installing and using a digital contact tracing app that would…

Stepwise School Opening Online and Off-Line and an Impact on the Epidemiology of COVID-19 in the Pediatric Population
[pre-print, not peer reviewed] Yoon et al. observed no increase in pediatric COVID-19 cases following school re-openings in South Korea. School openings were delayed from March 2020. Instead, online classes began on April 9 and in-person classes started between May 20 to June 8 in four steps by different grades. As of July 11, among the…

Was School Closure Effective in Mitigating Coronavirus Disease 2019 (COVID-19)? Time Series Analysis Using Bayesian Inference
Iwata et al. fit a time series model to case data through March 31 to assess effectiveness of school closure in Japan. They assumed the effect of school closures on March 1st would become apparent 9 days following closure. They found the expected daily change in the number of cases pre- versus post-school closures was 0.08 (95% CI -0.36, 0.65). As this estimate was greater than zero, the authors concluded…
Social Distancing Laws Cause Only Small Losses of Economic Activity during the COVID-19 Pandemic in Scandinavia
Sheridan et al. used real-time transaction data from a large Scandinavian bank to estimate reduction in aggregate spending due COVID-19, and found that most of the economic contraction was due to the pandemic in Scandinavian countries, rather than lockdown policies. In Sweden, there was a 25% reduction in aggregate spending as a result of the pandemic. In Denmark, where policies to control the pandemic where imposed,…

Findings from a Probability-Based Survey of U.S. Households about Prevention Measures Based on Race, Ethnicity, and Age in Response to SARS-CoV-2
Self-reported individual behaviors to protect against SARS-CoV-2 exposure (e.g. wearing a facemask, maintaining physical distance from others, etc.) were nearly identical across white, African American, and Latino respondents in a nationally representative survey (n=1,395) of American households. Relative to white participants, African American and Latino participants were less likely to install an app that asked…
Enacting National Social Distancing Policies Corresponds with Dramatic Reduction in COVID19 Infection Rates
An analysis of daily COVID-19 case counts and average mobility data concluded that social distancing policies reduced global COVID-19 transmission by 65% over a two-week time period. McGrail et al. also conclude that statewide social distancing policies in the US correspond with reduced COVID-19 transmission, which was found to be proportional to reductions in mortality. McGrail et al. (July 30, 2020). Enacting National Social Distancing…

Social Distancing Responses to COVID-19 Emergency Declarations Strongly Differentiated by Income
Weill et al. found that social distancing following US state-level emergency declarations substantially varied by income. Using mobility measures derived from mobile device location data, wealthier areas decreased mobility significantly more than poorer areas. Wealthy areas went from most mobile before the pandemic to least mobile, while the poorest areas went from least to most mobile. The authors suggest that previous research showing that lower income communities have…

Prevalence of Mask Wearing in Northern Vermont in Response to SARS-CoV-2
[pre-print, not peer-reviewed] During a 2-week period of business re–opening in mid-May following an extended statewide lockdown in Chittenden County, Vermont, observed face mask use at eight different business types was 76% overall, with higher mask use among females compared to males (84% vs. 68%). Older people (>60 years old) were most likely to wear a mask (91%) and children…
