CME Credits: 1.00

Current US Centers for Disease Control and Prevention COVID-19 guidance for nonimmunocompromised individuals allows ending isolation after 5 days if the individual is asymptomatic or afebrile with improving symptoms. Culturable virus, currently the best proxy for transmissibility, is reported after day 5. It has been proposed that rapid antigen tests (RATs) might assist in determining isolation periods. However, while RATs correlate with culture positivity during early infection,, there are minimal data after day 5, when persistent RAT positivity has been reported., We sought to compare rates of RAT positivity, COVID-19 symptoms, and positive viral culture starting day 6 after a COVID-19 diagnosis.
