Children who tested positive for COVID-19 in 2022 were contagious for a median of 3 days, regardless of vaccination status, suggesting that 5-day school isolation policies are sufficient amid Omicron variant predominance, University of Southern California (USC) and Stanford University researchers report today in JAMA Pediatrics.
...People with COVID-19 should isolate for five days, the CDC said. And, if they are asymptomatic or their symptoms are resolving (without fever for 24 hours), they should follow that by five days of wearing a mask when around others to minimize the risk of infecting people they encounter.
The change is motivated by science demonstrating that the majority of COVID transmission occurs early in the course of illness — generally in the one to two days prior to onset of symptoms, and then two to three days after, according to CDC guidance.
Additionally, the CDC also recently updated the recommended quarantine period for anyone who knows they were exposed to COVID-19.
Children lost out on more than one-third of a school years’ worth of learning during the COVID-19 pandemic, an analysis has found. Their mathematics skills were more affected than their reading abilities.
