This is a key point that should be discussed more (if you don't understand it) or repeated more (to get it past other, now outdated paradigms).

And yes. There is⏩actual evidence⏪ that small particle *aerosols* (SPA; not droplets-although I can't find the specific SPA size range in this paper) infect & result in inflammation and can generate ARDS (highlighted below were SPA infected) in primates
ajp.amjpathol.org/article/S0002-…

Some studies don't adequately discriminate larger droplets from SPAs in their "aerosol" so which was the more likely, or whether both were equally likely, cannot be determined and so the precise route remains unclear
e.g. nature.com/articles/s4158… and sciencedirect.com/science/articl…

Disappointingly - perhaps because they are influenced by the those outdated paradigms - these👆 sorts of studies, for the sake of some added distance, could contribute vitally useful new transmission data, but just fall short.😡

There is of course lots of ancillary theory & evidence for infectious aerosols (not for droplets though) being produced in daily activities, existing via lab work and *actually occuring* via capture and experiment-a good review with lots of info & links is sciencedirect.com/science/articl…
