Temperature and Humidity Effects on SARS-CoV-2 and Related Coronaviruses

Abstract

In all studies investigating temperature and humidity effects on COVID-19 and related coronaviruses, low air temperature (AT) and low relative humidity (RH) favored the survival of both SARS-CoV-2 and related coronaviruses; however, inactivation was more rapid at increasing RH levels and at high AT [1-8]. In each case, high temperature at high RH were found to have a synergistic effect on the inactivation of coronavirus viability while lower temperatures and low relative humidity support prolonged survival of viruses on contaminated surfaces [3]. The results of these studies suggest that RH has a greater effect on viral stability/inactivation that AT [2].
