Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

The primary goal of this study is to determine the most effective SARS-CoV-2 testing strategy for successful return of in-person school in the under-served communities of St. Louis. Regular screening testing has been recommended by the CDC as an additive mitigation strategy for in-person schools in areas of high community transmission. We will compare the effectiveness and acceptance of two different school-based testing strategies among students and school staff (symptomatic testing only versus weekly surveillance testing plus symptomatic testing), measuring school-based SARS-CoV-2 transmission through a cluster randomized trial.
