GAINESVILLE, Fla. – Many high school students on day nine or later of their COVID-19 quarantine period tested positive for the virus, a University of Florida study published in JAMA has found. The finding suggests schools should adopt a policy of testing quarantined students if they return to class before the end of the standard 14-day quarantine period in order to limit COVID-19 transmission in schools.
