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 stabilityinactivation that AT 2.
