Maternal Transmission of SARS‐COV‐2 to the Neonate, and Possible Routes for Such Transmission: A Systematic Review and Critical Analysis
Walker et al. conducted a systematic review with 49 studies including 666 neonates to estimate the risk of neonatal SARS-CoV-2 infection. In total, 8/292 (3%) vaginally delivered neonates and 20/374 (5%) Caesarean births developed confirmed SARS-CoV-2 infection. Walker et al. (June 12, 2020). Maternal Transmission of SARS‐COV‐2 to the Neonate, and Possible Routes for Such Transmission: A Systematic Review and Critical Analysis….
Natural History of Asymptomatic SARS-CoV-2 Infection
Sakurai et al. reported a case series of 90 patients from the Diamond Princess cruise ship who were asymptomatic when they tested positive for SARS-CoV-2, and remained asymptomatic throughout the course of the infection. The median number of days between the first positive PCR result and the first of the two serial negative results was 9 days (IQR 6-11, range 3-21), and the cumulative percentages…
Duration of Viral Shedding in Asymptomatic or Mild Cases of Novel Coronavirus Disease 2019 (COVID-19) from a Cruise Ship: A Single-Hospital Experience in Tokyo, Japan.
Miyamae et al. found the median duration of viral shedding among 23 passengers from the Diamond Princess cruise ship with asymptomatic or mild SARS-CoV-2 infection was 19 days (range 6-37 days) from initial viral detection. Eight people (35%) had another positive PCR result after testing negative once. Miyamae et al. (June 8, 2020). Duration of Viral Shedding in Asymptomatic or Mild Cases of…
Effect of Social Distancing on COVID-19 Incidence and Mortality in the US
[pre-print, not peer reviewed] VoPham et al. used nationwide smartphone GPS data for 3,054 counties (94%) in all 50 states and Washington, DC, to estimate county-level social distancing based on (1) change in average distance traveled (per device), (2) change in non-essential venue visitation (e.g., hair salons), and (3) the probability that two users were in close proximity. Stay-at-home orders were associated with a…
Use of Face Coverings by the Public during the COVID-19 Pandemic an Observational Study
[pre-print, not peer reviewed] Arp et al. examined the use of face coverings at grocery stores across 20 counties in Wisconsin between May 16 and June 1, 2020. Of 3,271 people observed, 41% used face coverings. Adults (aOR=1.65), females (aOR=1.43) and customers at a more expensive grocery store (aOR=1.95) were more likely to be wearing face coverings.

Knowledge and Practices Regarding Safe Household Cleaning and Disinfection for COVID-19 Prevention – United States, May 2020
An internet survey of 502 US adults conducted in May 2020 identified knowledge gaps in several areas regarding household cleaning and disinfection, including safe storage of hand sanitizers, cleaners, and disinfectants. Thirty-nine percent reported engaging in high-risk practices in order to prevent SARS-CoV-2 transmission, such as washing food products with bleach, applying products to bare…
Seroprevalence of Anti-SARS-CoV-2 IgG Antibodies in Geneva, Switzerland (SEROCoV-POP): A Population-Based Study
*A population-based household serosurvey conducted in Geneva, Switzerland found that accounting for test validity (sensitivity and specificity) using Bayesian methods, seroprevalence increased over the first three weeks of the repeated survey (3.8% in week 1, 8.5% in week 2, and 10.9% in week 3). Seropositivity was significantly lower among those 5-9 years old (RR=0.32, 95% CI 0.11-0.63) and those over 65…
Rationing Social Contact during the COVID-19 Pandemic: Transmission Risk and Social Benefits of US Locations
Benzell et al. ranked the relative transmission reduction benefit and social costs (including employment costs) of closing 26 categories of public spaces in the US. The authors concluded that banks, dentists, colleges, places of worship, and auto repair shops should be opened before gyms andcafes. Among stores, they found that electronics and furniture stores should be opened before liquor and tobacco stores. Banks, general…
The Psychological Impact of Preexisting Mental and Physical Health Conditions during the COVID-19 Pandemic
As young adults may have less stability in their careers, education, and social lives than other demographic groups, Alonzi et al. identified young adult subgroups at increased risk for depression and anxiety during the COVID-19 pandemic. They found that gender non–binary participants followed by females and those with pre-existing health conditions reported a higher prevalence of emotional distress. Alonzi et al. (June…
Work-Related and Personal Factors Associated with Mental Well-Being during COVID-19 Response A Survey of Health Care and Other Workers.
[pre-print, not peer reviewed] Evanoff et al. report that the prevalence of anxiety, depression, and work exhaustion were higher in clinicians than non-clinicians among 5,550 faculty, staff, and post-doctoral fellows surveyed at a university and academic medical center. Community or occupational exposure to COVID-19, lack of support from supervisors, younger age, and family/home stressors were also risk factors…
