Aerosol and surface stability of HCoV-19 compared to SARS-CoV-1 [pdf]

The slightly tangential question I had was, OK, a potential active lifespan of 2-3 hours in aerosol form, but in a normal environment, how long is it likely to remain in aerosol form before settling on a surface, and in what environments is it likely to remain airborne for 2-3 hours?

That's a good question, no doubt. A related one I had was (and maybe I missed this), but what's the "dose" of virus one needs to get infected? In the discussion of decay / half life of the virus on surfaces and in the air, I wondered about this. It's one thing if the virus can hang around for three hours and infect you at any time, and another thing if it's in the air for three hours but decays at ____ rate and can only infect for 1 hour.

TCID50 gives you information on infectivity. Not as good as LD50 though https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4861875/
