This might be silly but is there a way to simulate physically how far aerosol droplets spread?
Like, if I buy a certain kind of air freshener spray, can I spray that to simulate a sneeze, and say "If you can smell a fresh pine scent, you have a 50/50 chance that you would catch COVID / flu / RSV / etc at this range"
Boost if you like
Generally what people say is that it is like smoke. How far away can you smell smoke? On a still day, no wind, I have looked around and seen that the smoking person was a block away
This is, of course, not what people want to hear
I've seen some studies that indicate that you can catch covid from a single viral particle. You don't need a whole bunch
