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
I don’t think it’s possible to estimate probability of you catching it, because that depends on things about you, such as your immunity.
Also, when it comes to COVID, aerosol and droplets are two different things. Droplets are what you probably think they are, the reason you cover your mouth when you sneeze. They are big enough they will fall from the air. Aerosols are smaller and will continue to float in the air, basically invisible. 1/2
It is possible to get a visual of the droplets by sneezing in a cold environment, where you can see your breath. But it’s the tiny aerosols that linger invisibly in the air that pose the real threat of catching or spreading COVID. Aerosols are produced even just from breathing, no need for a sneeze.
Hope that, while not exactly an answer to your question, was somewhat helpful. 2/2
