There will be outbreaks on college campuses, that is one of things we are certain about for Fall.
I wonder if the author feels the same about opening K-12 schools? I have said this on other threads, but I am more concerned about S21 in a HS where 3500 students and staff are in one building every day for 7-8 hours than I am for D19 at her LAC.
Those 3500 students and staff will share germs indoors for 7-8 hours, then go home to their parents, siblings, SOs, kids, etc…share/exchange germs with those people, many of whom had multiple exposures during their days…then return to the HS the next day. Rinse and repeat.
