I have been predicting a bunch of multi-layered quarantines:
—Very local—keep unauthorized people away from health care workers and facilities—military style perimeters
-—Hot spots—lots of positives—keep locals in and non-locals out
—States—state lines roadblocks. This is to allow the states to get a handle on cases to protect their health care facilities
—Others as needed on ad hoc basis.
These would all be announced at the state level, one at a time.
Needless to say (these days the public officials are so brain dead that maybe nothing is needless to say :-( ), the airports would be closed.
Well, hopefully if it comes to those measures, they will actually work.
