CDC is recommending schools stay closed for 14 days. This is the approx incubation time. But with last weeks sudden rise in infections I’m guessing they will restart the 14 day clock to next week. So 3 weeks from next Mon 3/16/20.
Some school districts are already doing this be moving spring break up to give them 3 weeks of closure.
I’ll bet schools will resume 4/6.. ..unless we are all dropping like flies.
