A study just published in JAMA Pediatrics found that kids infected with the Covid-19 coronavirus can continue to shed the virus for an average of about two weeks even though they never develop any symptoms. (Requiring oxygen meant requiring additional oxygen since all kids require oxygen, unless they happen to be Henneguya salminicola, a parasite that does not require oxygen and can infect the flesh of Chinook salmon.) Twenty of the kids had moderate Covid-19 symptoms, and 46 had mild symptoms. Twenty (22%) of the kids never ended up developing symptoms, remaining asymptomatic throughout the period that they were observed. The medical teams then had these samples tested for the presence of SARS-CoV2 genetic material, otherwise known as SARS-CoV2 RNA. For all of the kids in the study, SARS-CoV-2 RNA continued to appear in the samples up to an average of 17.6 days. In fact, four of the asymptomatic kids still were testing positive for SARS-CoV-2 RNA at the 21 day mark and one at the 28-day mark.
