If evaporation matters, then transmission rates should depend strongly upon humidity. However, there are studies saying transmission rates decrease with relative humidity. Maybe drying is irrelevant, or maybe there is another factor, or maybe the studies are wrong.

I distinctly remember reading recently that it's absolute, not relative, humidity that counts. The article did not give a reason, nor can I remember the source (sorry).

I actually can't tell whether evaporation is good or bad. If a droplet evaporates, does the virus die or does it float freely through the air?
