The new coronavirus is very sensitive to ultraviolet light, and ultraviolet light is absolutely effective in destroying the virus. This is also one of the disinfection methods recommended in the treatment protocol for novel coronavirus pneumonia issued by the Health Commission. UV disinfection is absolutely effective, but it is not necessary to use UV disinfection at home. UV disinfection is mainly used in medical environments, and is often used in wards and clinics. UV rays can damage the surrounding environment, such as destroying plants and being harmful to people, so people should not stay in an environment where UV rays are sterilized. The easiest way to disinfect with ultraviolet light in your life is by sunbathing. You can dry your bedding in the sun, and walking in the sun can also destroy viruses. Source: Dr. Yurai
