In a new study, Yale epidemiologists hit upon a more practical strategy for COVID surveillance on the part of companies, teams, schools, and communities. With frequent, regular rapid antigen (RA) testing, plus isolating people who test positive, organizations can cut the risk of out-of-control COVID outbreaks effectively and make long quarantines a thing of the past, the researchers say.
