At a virus density comparable to that observed in SARS-CoV-2 infection, an UV-C dose of just 3.7 mJ/cm2 was sufficient to achieve a more than 3-log inactivation without any sign of viral replication. Moreover, a complete inactivation at all viral concentrations was observed with 16.9 mJ/cm2. These results could explain the epidemiological trends of COVID-19 and are important for the development of novel sterilizing methods to contain SARS-CoV-2 infection.ELETTRONICOenArticle10.1038/s41598-021-85425-w2-s2.0-85102734901https://www.nature.com/articles/s41598-021-85425-whttps://api.elsevier.com/content/abstract/scopus_id/85102734901FIS/05 - ASTRONOMIA E ASTROFISICA
