Agreed, it is not a given that masks are the answer but at least anecdotally they seem to have benefits and they are a minor inconvenience. It is all about assessing the risks. If you have contact with few people, then masks are not really improving your odds that much. If you deal closely with lots of people, it probably betters your odds tremendously.
I find masks useful because it reminds people about keeping distance. And it keeps people from freaking out. It might be helpful. I doubt I have the virus, I don’t interact with people outside of work, and at work we do keep distance, wear masks, and we have cleaning stuff and hand sanitizer everywhere. We temperature check every day, and everybody is certifying that they do not have symptoms.
We’ve had 43 people report possible covid. Every one got tested. only 10 were actually positive. No contact at work ever got a positive test.
Still, I wear my zombie mask. Mostly so if I did manage to catch it, and I sneeze of cough or shout, I won’t infect people.
Daughter and I are going to Disney in a couple of weeks, and she is hopeful that they are still enforcing their mask rule, and I’m just hoping they are not adjusting their crowd size because I don’t want the long lines.
