So the interaction between ventilation, temperature & humidity on #SARSCoV2 viability and transmission is interesting. Bad news in terms of transmission seem to be poor ventilation, lower temperature & lower humidity. How to balance them? Need serious expertise to get this right.

There are papers if you google, but some info also here:https://twitter.com/VirusesImmunity/status/1320430675099635714 …

Thanks, that's interesting about masks raising RH.

If I may? When cold, dry air is warmed, the relative humidity indoors drops by ~20%. Such a drop in humidity makes it easier for airborne viral particles to travel as there are fewer H2O molecules in the air that restrict the travel of the molecules through the air. 1/2

2/2 Additionally, cilia do not function as well in dry conditions, meaning they cannot expel viral particles as well as they otherwise would.

Indoor RH during winter can drop dangerously low. Let’s humidify our homes. As for public buildings, please sign our petition to the WHO to set guidance on humidity to combat respiratory infection. (End)
