Temperature and humidity and Covid

There is some research to show that higher humidity levels can help fight the Coronavirus in your indoor spaces. Op-ed: Humidity can aid in the fight against COVID-19 | News | Harvard T.H. Chan School of Public Health

There could be 3 reasons for this: Studies suggest that

  1. higher humidity can enhance the body’s ability to fight off infection;
  2. that the coronavirus decays faster at close to 60% relative humidity than at other levels;
  3. and that drier air can lead to greater numbers of tiny coronavirus particles that travel farther and penetrate deeper into the lungs.

I’ve never had much luck with humidifiers, however, we have stopped running the fans when we take a shower and  don’t wipe down the water from the tile and glass doors.  I leave the door open to the hall when I shower.  It’s a small amount, to be sure, but right now it’s OK to steam up the mirror.

Also, the new case load and death rate from Covid is also affected by the temperature and humidity of the country, as research has found, and could be important for policy.  In the U.S., however, it is just easier to blame President Trump.
