An Overview on the Role of Relative Humidity in Airborne

Humidity affects both the evaporation kinematics and particle growth. In dry indoor places i.e., less humidity (< 40% RH), the chances of airborne transmission of SARS-CoV-2 are higher than that of humid places (i.e., 90% RH). Based on earlier studies, a relative humidity of 40–60% was found to be optimal for human health in indoor places.Get price
