The novel coronavirus pneumonia diagnosis and treatment guidelines issued recently indicated that 5% alcohol, ether, chloroform, formaldehyde, chlorine disinfectant, peracetic acid and ultraviolet rays could inactivate the virus. Therefore, the medical ultraviolet lamp is effective in killing coronavirus.

UV sterilization mainly acts on nucleic acid, so that protein is affected and inactivated, so whether it is skin, bacteria, or viruses, fungi, most of them have effect. The commonly used ultraviolet lamps are of UV-C type, with the main band of 253.7nm, which can act on the genetic material DNA of organisms, causing DNA damage and bacteria death; there is also a band of 185nm, which is often referred to as ozone ultraviolet lamp, which can produce ozone with strong oxidation with air, and can also effectively eliminate bacteria.

In addition, ozone sterilization is also a common way of sterilization. Ozone is a broad-spectrum bactericide, which can kill bacterial reproduction and spores, viruses, fungi, etc., and destroy botulinum toxin. When the oxygen concentration is higher than 60.3mg/m3 and the action time is more than 15 minutes, the surface coronavirus can be completely killed.

After going home, can the clothes and masks be disinfected with a disinfecting cabinet and reused?

The disinfection cabinet combines ultraviolet lamp, ozone, high temperature and other disinfection methods. It can also dry clothes, masks and other functions. It can effectively kill the remaining bacteria and viruses of objects, clothes, masks, etc., and effectively prevent virus invasion.
