> Nobody on campus has tested positive yet (as far as we know) Have any been tested? How many have been tested? I am not sure how one determines "risk" (?) with this asymptomatically contagious disease that lingers on surfaces and can travel in aerosal form a few meters. The people at "risk" are the older generation [the parents ..], and movement of people contributes to spreading of the disease. I think MIT is just off loading hot potatoes here.
