Ultraviolet radiation from the solar spectrum can quickly eradicate coronavirus infection. The effectiveness of ultraviolet radiation was reported by an immunologist, professor of Milan State University Mario Clerici in an interview with RIA Novosti.
The expert spoke about the experiment. So, the researchers put Sars-CoV-2 in water droplets in order to reproduce the effect that occurs when a patient with coronavirus coughs. The materials were exposed to various doses of solar radiation: shortwave (ultraviolet C – UV-C), longwave (UV-A) and medium wave (UV-B).
It turned out that exposure to ultraviolet radiation, even in small doses, leads to the inactivation of the virus within a few seconds, Clerici said. “The sun’s rays, penetrating into the earth’s atmosphere in summer, are able to almost completely kill the virus contained in droplets of saliva that occur when coughing or talking with an infected person,” the scientist explained.
The specialist also explained the high prevalence of coronavirus in India, Pakistan and Bangladesh. According to him, this is due to the monsoon climate, in which in the summer, due to heavy rainfall, little sunlight enters the atmosphere.
Earlier, the head of the Department of Microbiology, Virology and Immunology of the First Moscow State Medical University named after Sechenov, Academician of the Russian Academy of Sciences Vitaly Zverev said that hot summer weather is unlikely to reduce the activity of the coronavirus, and the destructive effect of ultraviolet radiation turned out to be overestimated, because it applies only to street surfaces. He noted that in order to prevent infection, it is necessary first of all to observe social distance, because the infection is transmitted mainly by airborne droplets from person to person.
