Pretty sure this is only true for some microorganisms. Well, I'm not sure about length of survival time, but I've definitely see studies that have shown that lower humidity causes respiratory droplet evaporation, resulting in more airborne virus particles and increasing spread. There is some evidence that this increases infection rates
I mean yes you’re right but also most microorganisms that cause disease die quickly without their little droplets and particles to cling to.
On the other hand, procedure masks rely on those droplets to be the microorganism carriers that they can more easily stop instead of falling back on electrostatic attraction as the lil guys float through em.
In conclusion, infectious disease is a land of contrasts and while hospitals can rely on technologically advanced hvac systems to maintain a narrow range of temperature and humidity that represents a trade off between reduced micro environments, reduced airborne transmission and safely storing all their poultices and potions, normal people need to just do our best and maybe should accept the reduced mold and microorganisms over all in exchange for more chance of airborne transmission when cleaning our homes and workplaces (which are all fucked if there’s airborne transmission anyway because no one has appropriate air cleaners in their home or workplace).
