Epidemics caused by pathogenic viruses are a severe threat to public health worldwide. Electromagnetic waves are a type of noncontact and nonionizing radiation technology that has emerged as an effective tool for inactivating bacterial pathogens. In this study, we used a 9.375 GHz electromagnetic wave to study the inactivation effect and mechanism of electromagnetic waves on MHV-A59, a substitute virus for pathogenic human coronavirus, and to evaluate the inactivation efficiency on different surface materials. We showed that 9.375 GHz electromagnetic waves inactivate MHV-A59 by destroying viral particles, envelopes, or genomes. We also found that 9.375 GHz electromagnetic waves can decrease the infectivity of viruses on the surface of inanimate materials such as plastic, glass, cloth, and wood. In conclusion, our results suggested that the 9.375 GHz electromagnetic wave is a promising disinfection technique for preventing the spread and infection of pathogenic viruses.
由病原病毒引起的传染病是全球公共卫生的严重威胁。电磁波是一种非接触式、非电离辐射技术，已成为灭活细菌病原体的有效工具。在这项研究中，我们使用 9.375GHz 的电磁波来研究电磁波对 MHV-A59（一种人类致病性冠状病毒的替代病毒）的灭活效果和机制，并评估其对不同表面材料的灭活效率。结果表明，9.375GHz 电磁波通过破坏病毒颗粒、包膜或基因组来灭活 MHV-A59。我们还发现，9.375GHz 电磁波可以降低病毒在塑料、玻璃、布和木材等无生命材料表面的感染力。总之，我们的结果表明，9.375GHz 电磁波是一种有前途的消毒技术，可用于防止致病性病毒的传播和感染。
