Twice-weekly COVID-19 testing of residential students = effective infection mitigation strategy at colleges and universities

 Key Points

Question  What is the association between COVID-19 testing and case rates on residential college campuses?

Findings  In this cohort study of 18 Connecticut colleges and universities, infrequent COVID-19 testing of residential students was not associated with decreased transmission, whereas testing of residential students twice per week was associated with decreased transmission during the 2020-2021 academic year.

Meaning  Findings suggest that twice-weekly COVID-19 testing of residential students may serve as an effective infection mitigation strategy at colleges and universities.
