Schools already are the ready made aquarium for passing stuff around. One kid gives it to 5 in a single day. Then those kids go home and the other kids go to their school and so on. That’s with normal transmission during seasonal fluxes. Our daycare went through multiple rounds of viruses in June and July which was shortly after masks were dropped. Capped off by a second round of COVID in August (first go round was January). So it was Avery rapid set of punches and all offseason.
