Within the next week or so, I expect that essentially all US colleges and universities will be closed or converted to online-study only. I'm less certain about what secondary schools will do because there's considerable (medically misguided) pressure from parents to keep them open.
Fully agree, Dew. I've been in contact with most of the Big Ten schools and they are moving that way... Most will wait until after their Spring Break to implement the change. I've also spoken with a number of school districts in the Midwest and they are looking to implement home-school / online-study for 10-21 days.
