Well, it's probably less of a concern for PWME, since many of us have far less contact with others than the rest of the population. I encounter (not closely) a few people every few weeks. So the chances of me getting a virus and spreading it are quite low. Compare that to the typical person. Even if the whole population of PWME was to do the maximum possible masking, cleansing, etc, what effect would that have on global spread of covid, especially since there seems to be very little prevention practiced by the majority? The situation would be different if masking was practiced by 90+% of the population, but that's not what I see here. I did mask when the buildings had signs saying masking was required, and most people did wear them.Asymptomatic spread is very common— around 20% of covid cases are asymptomatic it seems. So when and where pwME mask is germane to both!
FWIW, my main reason to not mask is the local climate and wearing glasses. I'm effectively blind for 5-10 minutes when I walk into a building while masked. It takes awhile for thick glasses to warm up enough to not fog up.
