Ridgewood NJ, a study conducted by the University of Florida and the Florida Department of Health, published in JAMA, investigated the impact of student quarantine and testing protocols at K-12 schools in Alachua County, Florida. Data indicate that the COVID-19 incubation period in children is 6 to 7 days, shorter than the 4 to 5 days in adults. The county implemented 14-day self-quarantine for students exposed to known COVID-19 cases, and students were allowed to return to school early if they received a negative RT-PCR diagnostic test on Day 9 or later.
