Increasing Temperature and Relative Humidity Accelerates Inactivation of SARS-CoV-2 on Surfaces

Aug 17, 2020COVID Literature Appraisal, Epidemiology

Opinion: Mitigating the transmission of SARS-CoV-2 in clinical settings and public spaces is important to reduce the number of COVID-19 cases till a successful vaccination programme is in place. This study can influence public health measures to cut the transmission of SARS-CoV-2.These data are most relevant for indoor conditions and can help decide post-usage disinfection protocols for hospitals, offices, schools and public transport vehicles.Temporarily increasing temperature and/or RH in these spaces, once they are vacated, may complement cleaning with chemical disinfectants to reduce potential fomite transmission. Also, PPE when used inappropriately can be a source of possible fomite transmission.
