You're overstating that number as of today.
But in two weeks I'm betting it will be accurate.
What is interesting is how many of the Ivies have already done so.
Perhaps they are relying on the advice of their own faculty who specialize in medical and public policy fields.
I have added several of them to my twitter feed. Quite frankly, they seem to me to be the best source of information and advice at the moment.
There is a link up thread, but I will repost as a courtesy . On these threads, many of us discuss information previously posted. I for one prefer to post latest news rather than chasing down links for people
Here's a list of 50 Division I Schools.

This list only captures 1 of a dozen colleges closing within 100 miles of me (not including community colleges), and only 2 of 15 schools that have announced suspension of in person classes in Massachusetts. I'm sure this translates to Division II and III Schools, as well as non NCAA affiliated schools, local "Community Colleges", etc. I think it's pretty safe to say we are well beyond 100. Smaller schools just don't interest the media.
