Model-Based Evaluation of School- and Non-School-Related Measures to Control the COVID-19 Pandemic
An age-structured SARS-CoV-2 transmission model fitted to data from the COVID-19 pandemic in the Netherlands suggested that if methods to reduce the effective reproduction number (Re) of non-school-based contacts with non-school-based measures are exhausted or undesired and Re is still near 1, school-based prevention measures may be beneficial, particularly among older students. The authors provide examples from…
Transmission of SARS-CoV-2 Infection among Children in Summer Schools Applying Stringent Control Measures in Barcelona, Spain
A study of SARS-CoV-2 transmission among children and staff in summer schools in Spain during July 2020 found that the transmission rate under strict prevention measures was lower in school-like facilities than the general population. The authors compared transmission rates using a normalized effective reproduction number that accounted for the time spent in each setting….

Effectiveness of Three versus Six Feet of Physical Distancing for Controlling Spread of COVID-19 among Primary and Secondary Students and Staff: A Retrospective, State-Wide Cohort Study
Increasing physical distancing requirements in schools from ≥3 feet to ≥6 feet was not associated with a reduction in SARS-CoV-2 cases among students or staff if other mitigation measures were implemented, based on a retrospective cohort study of students (n=537,336) and staff (n=99,390) among 251 school districts with any in-person learning in Massachusetts during the…

SARS-CoV-2 Infections in Children Following the Full Re-Opening of Schools and the Impact of National Lockdown: Prospective, National Observational Cohort Surveillance, July-December 2020, England
Following the full reopening of schools in England in September 2020, COVID-19 cases among children lagged adult rates but ultimately followed similar trends. A strong correlation was observed in regional infection rates between adults and secondary (R2=0.96-0.98), primary (R2=0.93-0.94) and preschool-aged (R2=0.62-0.85) children. The November 2020 lockdown was associated with declines in adult infection rates,…
