Rapid and complete inactivation of SARS-CoV-2 by ultraviolet-C irradiation

Abstract The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has devastated global public health systems and economies, with over 52 million people infected, millions of jobs and businesses lost, and more than 1 million deaths recorded to date. Contact with surfaces contaminate...
