More good news and science on mask wearing

Tweet

So, 99% of my friends think wearing masks is a good thing, but some of my friends from the midwest US (where I grew up) are making very strong statement about "it doesn't help, I'm not wearing one, if you are a high-risk individual you should be vigorously isolating and let the rest of us get along with our unmasked lives." This, unfortunately, irritates me no end. She had a bunch of studies about mask permeability, which made her post sound both scinetifically convincing and religious ("I'm being loving to other people by showing them that wearing masks is not going to protect them.") So today I saw a new study, which is somewhat anecdotal, but includes some historical and current data. The conclusion was that where masks are worn, even if the virus is transmitted, the people contracting the disease either are asymptomatic or have milder symptoms and much less rise in deaths. Viral load. Viral load. Let me say it again: Viral load. This is something that has been studied even back in 1938 with flu virus. The less virus inside you (mouse, human, etc.) the fewer severe symptoms! I think that I have found the logical fallacy in the "masks don't filter out virus-sized particles so they are useless' crowd's argument. They believe in a completely full glass or a completely empty glass: 100% or 0%. The truth is, that life is almost never 100 or 0. Science is not saying it is. But given the choice, if wearing a mask reduces your chances of giving someone else a severe case, or even (gasp!) that your mask protects you from getting a severe case. it seems to me that we should just all mask up. (Of course I, and most of you, thought that anyway.) It makes me less nervous about going back to school in person. I am aware that science is still coming in on this very new thing. But, it makes total sense to me that nothing is 100% vs. 0%. Comments? (Link to article below)
