I was doing really well these last two weeks, and then I get a reminder that I'm not quite "normal" yet...

Today I ran into a grocery store to grab a couple things. At the end of one of the aisles, I saw an employee carrying a mop. I grabbed my item one aisle over (ironically, rubber gloves for cooking), but when I walked to the other end of the aisle, he was spraying something from an unmarked bottle and mopping a section of the floor. Of course my emet mind immediately thought someone had v* and he was spraying something to kill the germs. I dropped my item and left. (I can go back another day). When I got home, I wiped down my phone and purse. I took my shoes off outside, too.

I know it's EXTREMELY unlikely, but IF someone had v* and IF it were from something contagious, how small is the chance of exposure? There was no visible mess when I was near it, so it had to have been at least 3-5 minutes. v* particles aren't airborne that long, are they?
