Why does increased humidity decrease coronavirus "survival"? All news I can see scientist telling that the SARS-CoV-2 virus survive more in **cold and dry weather**. I can understand cold as hot weather will desiccate virus, but why dry weather. Would not dry weather dry droplets of saliva sooner also desiccate virus, would not humid weather support virus?

So I found this information regarding humidity from an article by MIT on corona:

1) **High humidity** leads to condensation of sneezing cough saliva particles sooner, so it does not spread to farther distance

2) **Low humidity** leads to less condensation and higher range of movement of saliva particle, hence more spread area.

Apparently it has to do with physics and range of infection not on survivability.
