All that needs done before a crowd forms is take temps. 99% of corona positives will have a temp (according to Mds) . That's why we saw China with their instant digital thermometer "guns" checking people before allowing entry. We can go to work, attend any Sports, go out to eat, do whatever we want. That's not much of an inconvenience . I'm also looking for Establishments to install UV Air purifiers that zap Viruses. Anything that removes the fear that is driving this thing. I have three in my home. They do a helluva job.
