Just talking generates respiratory droplets, ranging from 20 to 500 microm. This also shows what a mask does to reduce those droplets.
The very same droplets, 60-100 microm, can travel up to 3 ft just by breathing:

If you want to argue about quality of mask and what the means in terms of droplet size, then sure. But to say just by walking past an infected person at the store with neither wearing masks won’t lead in infection seems wrong.
Feels like I’m going crazy here. |
As I understand it from an article I posted a couple weeks ago it takes about 1,000 to infect you. Supposedly we expel about 900 or so per minute of normal talking and breathing. As mask can push that down to 500ish but still does not prevent it, just buys you a bit of extra time. And you might be going crazy, looked outside lately??
