I read the article Robert’s first link referred to. The conclusions are indeterminate with various results from different facilities. It certainly doesn’t seem to clear the way for wholesale school reopening. “ In fact, two preprints have reported that children with COVID-19 symptoms can have similar levels of viral RNA to adults. “Based on these results, we have to caution against an unlimited re-opening of schools and kindergartens in the present situation. Children may be as infectious as adults” Unfortunately the second link doesn’t work for me.
