Risk of Death among Teachers in England and Wales during the Covid19 Pandemic
[pre-print; not peer-reviewed] An analysis of publicly available data on COVID-19 mortality in England and Wales suggests that absolute mortality rates for teachers were low (under 39 per 100,000), but that secondary school teachers had slightly higher risk of dying of COVID-19 relative to all professionals and working-aged people. Primary school teachers were not at…
Stepping Back to School: A Step-by-Step Look at COVID Introduction, Spread, and Exportation
[Report, not peer-reviewed] Covasim, a model previously used to describe SARS-CoV-2 transmission among inter-personal contacts in King County, Washington predicted that the rate of introduction of SARS-CoV-2 into K-12 school classroom settings is proportional to the prevalence of SARS-CoV-2 in the community. The model is an agent-based model of contacts at home, school, work and…

Association of the Timing of School Closings and Behavioral Changes With the Evolution of the Coronavirus Disease 2019 Pandemic in the US
A model using population-based data from US states suggests that voluntary behavioral changes, such as reducing time at work, could have up to a 3-fold higher impact on reducing COVID-19 incidence compared to school closures. Each day earlier that school closures were implemented was associated with a 3.5% reduction in incidence, whereas each day earlier…
Reopening Schools in the Context of Increasing COVID-19 Community Transmission: The French Experience
Children and adolescents in France had lower risk of a positive SARS-CoV-2 PCR test and lower incidence of infection compared to adults during the first 2 months of the 2020-2021 school year (August to October 2020), though risk among older adolescents was close to that of adults. Schools re-opened with infection control measures in place,…

Two clusters involved probable educator-to-educator transmission that was followed by educator-to-student transmission in classrooms, resulting in approximately one half (15…

The Effects of School Closures on SARS-CoV-2 among Parents and Teachers
Sweden kept schools open for in-person instruction for younger students (primary and lower-secondary) while closing schools for older students (upper-secondary), allowing for an evaluation of school closures on SARS-CoV-2 transmission. The rate of SARS-CoV-2 infection among lower-secondary teachers (who taught children age 14 to 16 in person) was twice as high (7.4 cases per 1,000)…
Operational Strategy for K-12 Schools through Phased Mitigation Executive Summary
