> We know that kids under 10 are very unlikely to transmit Covid Source? My impression was that very few cases of transmission from young kids were observed, precisely because they were isolated. The adults might bring Covid into the house and spread it to the entire household, but the kids staying home means they can only get it from the adults. Nothing about being intrinsically less contagious, and everything about having an environment that minimizes contact.
