Key Points Question Is continuous SARS-CoV-2 testing accepted by children, parents, and childcare workers and can it prevent viral spreading in day care centers? Findings In this nonrandomized controlled trial, surveillance testing for SARS-CoV-2 among 954 eligible individuals was well accepted by children, parents, and childcare workers if saliva sampling at home was used. Mathematical modeling based on study and literature data identified biweekly testing of at least 50% of children and childcare workers as minimal requirements to limit secondary infections. Meaning These findings suggest that SARS-CoV-2 surveillance testing is feasible and allows for continued day care attendance for children during the COVID-19 pandemic.
