Italian scientists have conducted a study and found that ultraviolet radiation quickly and effectively destroys coronavirus.

Adnkronos agency reports on the work of Milan State University staff.

During the experiment, the virus was placed in water droplets in low, high and very high concentrations, and then exposed to various doses of solar radiation in the short wavelength range - ultraviolet C (UV-C).

“It turned out that exposure to UV radiation, even in small doses, literally within a few seconds can lead to the inactivation of the virus,” said Mario Clerici, professor at the University of Milan..

Since UV-C is completely absorbed when the sun's rays pass through the earth's atmosphere, the scientists set up the next experiment with ultraviolet long-wave (UV-A) and medium-wavelength (UV-B), with part of the solar radiation reaching the surface of our planet.

The result was the same: the minimum dose of solar radiation in a matter of seconds destroyed the coronavirus in water droplets almost completely.

According to Clerici, this suggests that the sun's rays entering the earth's atmosphere in summer can almost completely kill the virus, which is contained in droplets of saliva that occur when coughing or talking with an infected person..

This can explain the downward trend in the incidence of COVID-19 in Europe and most countries located in the Northern Hemisphere.. Moreover, in the Southern Hemisphere, where it is now winter, there is a real peak of infection.
