Think about this. Airborne viruses spread by catching a ride on water vapor, which you are constantly breathing out. So as it gets colder out that invisible water vapor can be seen as you exhale. You can watch the breathe go through and around the mask.
Covid isnt really airborne. More mouth to surfaces to hands to mouth.
Primary method of transmission is sharing a house with someone with covid and air conditioners
and everyone is constantly adjusting the now-moist mask with their hands, then touching every handle, button, tool, ...
And every time you need a drink of water or coffee or w/e during your work day, what do you have to do in order to get the mask down off of your mouth? Touch your face.
This is all engineered, I'm sure of it.
COVID is the common cold.
