Princeton University is another Ivy League school doing the same as Harvard.

University of Virginia also just announced today it is closing the campus after spring break and doing online classes.

I'm quite sure other schools will follow.

Local to me in Northern Virginia, Fairfax County Public schools are closing Monday for the teachers to have an in-service day to learn what to do in case the schools close and they have to go to online teaching. They are one of the biggest school systems in the country.
