| Popis: | SARS-CoV-2 transmission in K-12 schools was rare during in 2020-2021; few studies included CDC-recommended screening of asymptomatic individuals. We conduct a prospective observational study of SARS-CoV-2 screening in a mid-sized suburban public school district, to evaluate the incidence of asymptomatic COVID-19, document frequency of in-school transmission, and characterize barriers and facilitators to asymptomatic screening in schools. Staff and students undergo weekly pooled testing using home-collected saliva samples. Identification of >1 case in a school prompts investigation for in-school transmission and enhancement of safety strategies. With layered mitigation measures, in-school transmission even before student or staff vaccination is rare. Screening identifies a single cluster with in-school staff-to-staff transmission, informing decisions about in-person learning. The proportion of survey respondents self-reporting comfort with in-person learning before versus after implementation of screening increases. Costs exceed $260,000 for assays alone; staff and volunteers spend 135-145 hours per week implementing screening. Graphical Abstract Reports of rare SARS-CoV-2 transmission in K-12 schools are limited by lack of asymptomatic screening. Doron et al. report that public-school screening for asymptomatic SARS-CoV-2 in 2020-21 provides valuable data about in-school transmission risk and informs decisions about in-person learning, but human and financial resource requirements are high. |
