Masks, social distancing, but what about the weather?

Did you know that droplets of saliva can travel up to 18 feet in just five seconds when unmasked people cough? Did you also know that the weather has a bigger impact on COVID spread than social distancing? Since temperature, relative humidity, and wind speed all play a significant role, the researchers aimed to modify typical models to account for these climate conditions. They call their new weather-dependent variable the Airborne Infection Rate (AIR) index. The new findings appear in the journal Physics of Fluids.
