But the claims in your thread aren’t going to hold up. Look I agree the shortage a major crisis and we should go donate. But we should be truthful about what masks do and don’t. That’s pretty clear.

I’m not sure it’s that clear, though. The “optimal use” vs “actual use” scenario is something that we don’t really know how will play out in the US, since most people in the US have never even worn one for a short amount of time. The potential for accidental exposure is real.

I'm just going to be honest. The claims in your thread aren't correct or backed by science, and this whole thing has been a messaging disaster. People can learn to wear masks better very easily and even imperfect masks are better than no masks. The only crisis is the shortage.

I think you're vastly underestimating the difficulties of rapidly teaching a large population to wear something over their mouth & nose that they've worn before -- w/o touching it when it becomes uncomfortable. The Lancet, among others, acknowledges this.https://twitter.com/RVAwonk/status/1241498781457285120?s=20 …

Caroline Orr Bueno, Ph.D @RVAwonkThe Lancet recently touched on this. As they acknowledged, "not changing disposable masks could jeopardise the protective effect & even increase the risk of infection." They don't rule out more widespread use of masks -- if the evidence supports it. https://www.thelancet.com/journals/lanres/article/PIIS2213-2600(20)30134-X/fulltext … pic.twitter.com/hxAUIfXx7rShow this thread3 replies 0 retweets 4 likes -
First, the evidence supports it. Second, they have no issues with this alleged "incorrect mask wearing threat" in all the universal mask countries. If we can teach people how to wash their hands properly, we can teach them to wear masks better. (Washing hands properly is harder).

Plus, please not the recommendation in that Lancet article. "Perhaps it would also be rational to recommend that people in quarantine wear face masks if they need to leave home for any reason, to prevent potential asymptomatic or presymptomatic transmission". Which is the point.

I did. That’s why I said they leave the door open for more widespread mask usage — if the evidence supports it. Right now, it doesn’t, which is why they’re not being recommended in the US by any health agencies.

The reason they are not recommended is the shortage. The evidence is there. It's not even complicated. That's the painful truth. That's why I honestly think your thread isn't helpful. It's not correct. Masks aren't harmful. They are just short in supply.

We’ve seen Chinese helpers straight up tell Italy to start wearing masks. All the Asian countries that have already got it under control are looking at European countries without a prevalence of mask-wearing with disbelief.

Of course. It has been surprisingly well-received by many medical people frustrated and obviously aware that the messaging made no sense, and could see what was working in universal mask wearing countries. Plus that big paper on asymptomatic transmission. That seals it, really.
