Demonstration of Antiviral Activity of far-UVC Microplasma Lamp Irradiation Against SARS-CoV-2 by Woo Kyung Jung, Kun Taek Park, Kwang-Soo Lyoo, Sung-Jin Park, Yong Ho Park

Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is responsible for the coronavirus disease 2019 pandemic.
Methods: In this study, the antiviral activity of a far-UVC (222 nm) microplasma flat lamp against SARS-CoV-2 was evaluated.
Results and Conclusions: Immediate inactivation of up to 99.99% of the coronavirus was achieved with a dose of less than 8 mJ/cm2 and complete inactivation was observed by real-time RT-PCR; therefore, far-UVC (222 nm) is a promising candidate for the effective inactivation of SARS-CoV-2.
