Looks like the NFL is opening and playing their full season. I have read where the stadiums might set up portable tunnels that spray fans with a virus killing mist. Some of the other things being mentioned are masks and gloves, as well as cutting the stadium capacity to allow for seat spacing.

I have not heard anything about tests that require a fan to submit to a blood test including an antibody test.

Masks and gloves are pretty much useless. your doctor or dentist throws away the gloves they use after each use for a valid reason, cross-contamination. Unless you are wearing a medical mask all masks are good for is reduce the number of times you touch your face.

It looks like Abbott fast test could have a high percentage of false negatives according to one unpublished study.

So right now it does not appear like a panacea has been created.
