I think the best strategy is to try to come up with immediate and accurate testing and there seems to be progress in this area. If you don't have it you can't give it to anyone. I also read where dogs can detect COVID at 93% accuracy and 240 people an hour, which is one every 15 seconds. The problem sees to be it takes months to teach them.

There hasn't been much actual research but "experts" have said they think face shields are at least as protective as face masks. There's been players that played with face shields. I seem remember a Bronco did...was it Tony Dorsett?
