“It has long been known in virology that ultraviolet light has a detrimental effect on viruses, including enveloped viruses, such as the coronavirus. It acts on the cell wall, the envelope of the virus. It is known that in the light, which contains ultraviolet light, viruses die quickly enough, "- quotes RIA Novosti the words of a leading researcher at the laboratory of experimental virology of the FSBI" Research Institute of Epidemiology and Microbiology named after G.P. Somova »Galina Kompanets.
The virologist clarified that prolonged exposure to sunlight will not reduce the risk of COVID-19.
“In hot weather, a virus in the environment that gets from a sick person to the surface of something dies very quickly - within an hour for sure. But if this is direct contact, for example, when talking, when the face is not protected by a mask, when coughing or sneezing, infection can still occur, "Kompanets said.
Earlier, virologist, researcher at the Institute of Clinical and Experimental Medicine, Alexander Chepurnov, in an interview with Nation News, assessed the effect of ultraviolet radiation on COVID-19.
