This interview with @mtosterholm is 🔥. One of the clearest & most succinctly accurate 6-min summaries of where we are with Delta/COVID mitigation, masks, & vax (best part starts at 1:30).

A few quotes below. h/t @PPEtoheros, @citlanx

"This virus is an #aerosol. It’s transmitted in the air, just like we see with cigarette smoke. If you’re in a room and you have a covering on your face and you can smell* the smoke, then you know you’re also getting virus in there if in fact you had an infected person in there."

* (Editorial comment on the smoke smell comment. Aerosols in smoke come out as a concentrated plume, waft through the air, & build-up indoors. But the smell is from the gases & can go through masks, whereas aerosols are blocked. Good visual analogy, but it breaks down at smell).

"We know that face cloth coverings can reduce the amount of virus that you may inhale, but to be fully protected in the way that we believe … particular to this variant that we have today (Delta), you need to have the kind of protection that comes with an N95 or a KN95 for kids"

"That showed that if you wear a cloth face-covering you get about 5 add'l min. of protection in that room. If you wear a surgical mask you get about 10 min of extra protection." (quote cont'd ...)

(quote cont'd) "If you wear an #N95 respirator, not fitted, you get ~2.5 hrs of protection additionally. And if you wear a N95 that’s tightly face-fitted you may get up to 25 hrs of protection."

A variation on those data, w/ Delta update; 🧵 by @akm5376

"You tell me how you want to parse that out. I’d tell you if you were driving an old car & it only had an old, common seat belt in it – wear it! But if you had a modern car that had … airbags … I’d tell you to get that one! But I’d never tell you not to use the seatbelt
