I think part of the problem is you. You’re busy looking at other people to see what they’re doing and why they’re doing it instead of looking at yourself. Take a good look at yourself. Worry about yourself!
I see far too many people here and on other supposed Jewish sites that are very worried about what other people are doing and what other people are going to think about them. Perhaps you should be worried about yourself? are you being to think you have control over this disease? Don’t you realize it takes someone to be breathing with droplets coming out of their mouth staying in the air long enough for you to happen to walk by and for you to inhale it. And even so you don’t necessarily get sick. It could very well be that your body will fight it off and you’ll never know about it.
Stop playing Gd! Leave Gd to play Gd!
