I’m not talking about droplets versus aerosols. That’s not my expertise. But as a virologist I assure you: (1) virus infectivity has a half-life & (2) Dose matters. The radius from point source relative to surface area of a sphere matters when you’re speaking about infectivity.https://twitter.com/zeynep/status/1473024345140342787 …

There are lots of people on this bird app who can’t seem to distinguish that there’s a relationship between distance from a source and the risk of becoming infected / exposed to an infectious dose.. be it by whatever you wish to call it the mode of spread.

I think there’s a lot of people who conflate distance with a mode transmission, and that’s important because the mode of transmission implies many things about mitigation. On the other hand, I haven’t seen anybody serious in any side of this debate deny distance matters.
