UV-C irradiation is highly effective in inactivating SARS-CoV-2 replication

UV-C irradiation is highly effective in inactivating SARS-CoV-2 replication Abstract: The potential virucidal effects of UV-C irradiation on SARS-CoV-2 were experimentally evaluated for different illumination doses and virus concentrations (1000, 5, 0.05 MOI). At a virus density comparable to that observed in SARS-CoV-2 infection, an UV-C dose of just 3.7 mJ/cm 2 was sufficient to …
