Ultraviolet radiation of the solar spectrum can effectively and quickly destroy coronavirus. About it RIA Novosti was told by the Professor of Milan state University Mario Clerici.

According to Clerici, who led the collaborative study of immunology Milan University and specialists of the National Institute for astrophysics Italy, the ultraviolet radiation even in small doses, leads to virus inactivation.

“the Minimum dose of solar radiation in a matter of seconds destroyed the coronavirus in the water droplets of almost 100%. What does it mean? The sun’s rays in summer, penetrating the earth’s atmosphere, is able to kill the virus, contained in droplets of saliva that occur while coughing or talking with an infected person,” he said.

The Professor explained that the study COVID-19 were placed in drops of water, when it was proved the effectiveness of ultraviolet radiation at three different types of virus concentrations.


This, says Clerici, due to the decline in the incidence of COVID-19 in countries where it is currently summer and growth where it’s winter.

“Of course, there are exceptions. Thus, the high prevalence of the virus is observed today in India, Pakistan and Bangladesh. However, this is due to the monsoon climate in the summer due to heavy rains the atmosphere gets a little sunlight. In addition, in the study of the current pandemic, we cannot ignore social factors,” – said the scientist.

Rambler wrote that the outbreak of the coronavirus began in China in December 2019. According to recent figures, worldwide, the number of cases exceeded 14.4 million people.
