SARS-CoV-2 Cluster in Nursery, Poland. Emerging Infectious Diseases
A SARS-CoV-2 outbreak was identified in a nursery in Poland in late May. The index case was a nursery worker who reported family contact with a symptomatic SARS-CoV-2-infected person, resulting in a cluster of 29 cases and positivity among 27% of contacts (compared to national estimates of 1%). Twelve of those infected were children’s family…

Safely Reopening K-12 Schools During the COVID-19 Pandemic
[Pre-print, not peer reviewed]A modeling study of different school reopening plans indicated that plans that provide for multiple days in school in a row and divide students into smaller cohorts, as well as those that emphasize distance learning, are better able to suppress outbreaks and reduce risk if an individual with COVID-19 enters the community….

Testing Mobile Air Purifiers in a School Classroom Reducing the Airborne Transmission Risk for SARS-CoV-2
[Pre-print, not peer reviewed] Four mobile air purifiers with HEPA filters in a regular high school classroom were able to reduce the concentration of aerosols by more than 90% within less than 30 minutes compared to a neighboring classroom without purifiers. The authors further estimate that the inhaled dose via airborne transmission from staying in…

Excess Risk of COVID-19 to University Populations Resulting from In-Person Sporting Events
[Pre-print, not peer-reviewed] A modeling study using a stochastic compartmental model showed that in-person sporting events on college campuses could increase COVID-19 cases among the campus community. Even when COVID-19 cases were controlled both on-campus and among the larger population from which visitors to campus were drawn, such events presented a risk to the community….

Impact of University Re-opening on Total Community COVID-19 Burden
[Pre-print, not peer reviewed] A modeling study reported that university students returning to schools may contribute to increased community transmission of COVID-19, affecting at-risk members of the city community. This is supported by a scenario that if students engage in a 24% contact reduction compared to pre-COVID levels, the number of community infections would increase…

Transmission of SARS-CoV-2 in Children Aged 0 to 19 Years in Childcare Facilities and Schools after Their Reopening in May 2020, Baden-Württemberg, Germany
A German study analyzed new SARS-CoV-2 infections among children ages 0-19 years old from the time of school reopening through summer holiday (May to August 2020). A total of 137 index cases were identified who attended school or childcare settings for at least 1 day in their infectious period and among these, 6 (4%) index…

Potential Community and Campus Covid-19 Outcomes Under University and College Reopening Scenarios
[Preprint, not peer reviewed] A modeling study of various US college and university reopening plans (various fully open, hybrid, and fully virtual approaches) shows common reopening strategies could reduce student SARS-CoV-2 infections by 24%-26% and deaths by 36%-50%. Perfect testing and immediate quarantining of all students on arrival to campus at the start of term…
The Impact of COVID-19 on Student Experiences and Expectations: Evidence from a Survey. Journal of Public Economics
Among 1,500 undergraduates at Arizona State University, COVID-19 has led to negative effects on students’ current and expected outcomes: 13% have delayed graduation, 40% have lost a job, internship, or job offer, and 29% expect to earn less at age 35. These effects have been highly heterogeneous and followed existing socioeconomic divides. Lower-income students were…

The Urgent Need for Phased University Reopenings to Mitigate the Spread of COVID-19 and Conserve Institutional Resources A Modeling Study
[Pre-print, not peer reviewed] A modeling study indicates that phased reopening of college campuses (one-third of student population returning to campus each month) coupled with pre-arrival SARS-CoV-2 testing would reduce peak of daily infections compared to pre-arrival testing without phased reopening or no intervention at all. Phased reopening with pre-arrival testing could reduce the peak…

Impacts of K-12 School Reopening on the COVID-19 Epidemic in Indiana USA
[pre-print, not peer-reviewed] Espana et al. conducted a modeling study with varying degrees of school operating capacity and face-mask adherence to estimate the impact of a K-12 school reopening in Indiana on SARS-CoV-2 transmission. Their model indicated that, from August 24 to December 31, operating schools with high face-mask adherence would result in 3-times the…
