This leans into what I was thinking for the reasoning behind the message of "a facemask won't really help for the general population". There's soo many other vectors to be concerned about and diligence required that while effective for that one transmission vector, it won't help you from the others.
I've got one of those masks you use for spray painting with replaceable filters, based on the idea that if I'm in an environment where there are droplets containing the virus I don't want those droplets going into my lungs any more than if I'm in an environment with droplets of paint I want to keep those out of my lungs too.
Someone recommended 'em a few hundred pages back.
Now there are issues with mask cleaning.
Survival Lily pointed out that the best you can do is to leave the mask outside and hope UV and time deactivate the virus and that it's not drifting around in the air. Mind you, you can also just treat the outside of the mask as contaminated and only touch it with gloves. I got some nitrile gloves which were then still available. When I come back in I put all the clothes I wear into a hot wash/dry cycle and then iron them and take a shower. Anything I buy I wipe down with bleach-based cleaner.
Now is this foolproof? Definitely not. If the virus is endemic in the air and is airborne transmissible I'll probably get it, assuming I haven't already got it and recovered. Is it better than 'stay inside if possible, wash your hands when you come back inside, don't touch your face when outside'? I reckon it must be because I do all that shit too.
Now you can make a case for 'Most people are fucking idiots, let's give 'em the simplified version about hand washing'. Fair enough, that might well be the best option. What I object to is saying 'Masks don't work. Don't buy one'. When I go out shopping I see a lot of people in masks, a mix of surgical, N95 and decorating masks.
Masks clearly do work and it makes sense that they work given respiratory viruses'' main way to infect you is if you breathe them in, not because you touched a surface someone infected touched just after they contaminated their hands and then you just touched your eye or your mouth and they worked their way through to your lungs. The easiest way for a virus to infect you and wreck your lungs is if you breathe it in because then it doesn't need to travel. I'm not even sure you've got the right ACE2 receptors anywhere but your lungs.
Sure it'd be better if I had the full CDC recommended set up and didn't reuse masks, but that's just not possible to get. And in the study that I linked to it was just 'N95 mask or nothing' in a chaotic Chinese hospital, not in a US CDC regulated environment where people don and doff the full CDC PPE gear correctly and they
still found pretty good evidence it was worth wearing them.
And look, it seems the CDC agree
Looks like the recommendation to wear masks is coming soon -
More than 6.6 million Americans filed for unemployment benefits last week. The Democratic National Convention has been postponed, and the global death toll exceeds 50,000. The Navy removed an aircraft carrier’s captain after he spoke up about an outbreak.
