Rumor identification: UV light can effectively inactivate the new coronavirus. Rumor Analysis: 1. There are two main spectral lines of UV disinfection lamps: 253.7nm wavelength and 185nm wavelength. These two wavelengths of ultraviolet light can play a good disinfection role, where the former can act directly on biological cell genetic material, i.e. DNA / RNA, so that it is destroyed and lead to the death of bacteria; the latter can produce strong oxidation of ozone through the role of oxygen in the air, thereby killing bacteria and viruses. 2, the new coronavirus is replicated through RNA, and the process of UV killing is mainly on the nucleic acid (RNA) of the new coronavirus, and destroy the protein layer of the virus, and then affect its survival and replication ability, this process is medically called “inactivation”. Special note: Although UV lamps can inactivate the new coronavirus, but the human body for a long time by UV direct irradiation will also damage the eyes and skin, and may even occur more serious lesions, so when using UV lamps for disinfection, no one should stay in the house, and the windows should be opened for 30 minutes after disinfection.
