Abstract
Influenza A virus is one of the most serious diseases in the world. Therefore, it is necessary to find an effective and safe method to prevent the spread of the disease. A far-UVC at 222nm is considered safe and effective for viral and bacterial treatment. In this study, virucidal effects and the safety status of far-UVC microplasma were evaluated in vitro against influenza A virus H9N2 0130 strain. The results (from TCID50 and real-time PCR) indicated that a far-UVC inhibited influenza A virus depending on dosage. A far-UVC eliminated 99.99% of the virus at doses of 44 and 56 mJ/cm2 in clarified and un-clarified solutions, respectively. Moreover, a far-UVC 222 nm did not have any harmful effects in MDCK cell at dose 78 mJ/cm2. Our study provided useful information in a far-UVC application against influenza A virus.
