I asked because you posted as if a mask is supposed to protect the person wearing it. These days, that level of ignorance is weird for a layman. A doctor has to know better, but here you are a doctor, posting as if you do not know that. N95s? Yeah, I know those are supposed to protect the wearer, but they do not really seal tight enough for that. I have some kn95s, and it is obvious that they do not seal well enough to protect me very well. A mask is far more effective protecting other people from the person wearing it than it is at protecting the wearer from other people. For you to talk about your medical knowledge while posting as if you do not know that is inexplicably bizarre. Then you talk as if masks are useless because people touch their faces. As a doctor, why aren't you telling people not to touch their faces? Your attitude seems to be that people are too hopelessly stupid to do a simple thing like wear a mask without rubbing their hands all over everything and then all over their face. That is your reason to discourage people from wearing masks? Duh.
I'm not discouraging people from doing anything. I simply stated a possibility, and a very real one -- at that.
Do all of our schools just need to do a better job teaching coaches how to wear masks? Do football and basketball organizations need to re-teach all the refs? Should the old farmer on TV explain that he's actually safe because he wears his cloth mask *correctly*? Do we need more signs at the grocery store and church emphasizing the proper way to wear them? Would that fix anything? Maybe you can show me on the map where that is happening and has worked.
If you actually go out into the real world, you will see that just about everyone is wearing masks everywhere. Is it obvious on our curves in the U.S. that this has had a positive impact? Show me where. People act like Knoxvillians are running around in bare-faced orgies, and that's why the case-load is so high right now. 99% of the city is masked and has been for a while (unless magically eating, drinking, or calling plays/yelling at the ref).
Why did the local school system with a mask mandate "go virtual" due to illness and others that don't require them completed the semester in-person?
And, on N95s, that's the laziest excuse/explanation I've seen yet. If they actually do filter more effectively, you're telling me there hasn't been enough time (9 months) to make several for each American and have us fit-tested?
These are hard questions to answer if you are programmed to just accept what you are told and not analyze data or "think outside the box." Read the multiple studies on mask usage and influenza transmission, step back and look at current viral transmission, get out and observe behavior, or just turn on the TV and watch sports. Think. Then, get back to me.
