I had a doctor (retired US Army SF and civilian practice) tell me in early April. Shut everything down for a month, everything(!), except for the absolute most essential personnel and you may get a handle on it. If not it will be an issue for a very long time. I thought he was crazy! He said a few other things that made me scratch my head including in May saying that schools would not go back this fall which I called BS on but now wonder. He explained it was not the students health as the main issue but the peope they come in contact with and pointed to lower income families that have smaller living quarters, larger families, multi generational households, and multi family housing units all as an issue. He is sharp and he is harsh and I wonder if he was very much on point.
