Same stuff
@fly is referencing. I'll dig up something when I have time, it's not like I keep a library of links ready to go on my phone at the job,
I mostly go by abstracts or at least articles summarizing/referencing actual studies by universities, government health organizations, etc. Not just some news site or media organization or whatever. Or pharma companies either.
In short, the stuff just doesn't survive long outdoors, and you need to inhale a good deal more than just a single virus to get infected. That's why the environment you're in and the duration of exposure to the other people make such a difference.
Being at a ballgame (or political rally
) with people shouting for 2 or 3 hours, yeah there's some amount of risk there being around that many people for that long, even outdoors just due to the density/proximity for the length of time.
Passing someone on a walking trail for a few seconds? Nah.
I pull it up anyways, mostly out of courtesy, but also in case they happen to hack up a loogee at just that second and it somehow lands on my nose.
