A shoulder that can be definitive in the war with Covid. Mario Clerici, professor of General Pathology at the State University of Milan and scientific director of the Irccs of Milan Don Gnocchi Foundation, is the author, together with the research group of the National Institute of Astrophysics, of an all-Italian study published today in preprint on the Coronavirus: “We have shown that UVA and UVB rays from the sun completely kill Sars-Cov-2 within a few tens of seconds”. “This study – highlights Clerici at Adnkronos – is essentially the continuation of a previous work we did last year when we saw that UVC rays, which are a component of the sun’s rays that do not reach the earth, killed Sars- Cov-2 after a few seconds exposure. However, the UVCs do not reach the earth, so those data were only important from a certain point of view. Now, we have seen that even the Grapes and Uvb, which are the rays that reach the earth, tan and heat us, in a matter of a few tens of seconds they completely kill Sars-Cov-2 “.
“So – adds the immunologist – we have exactly replicated the data on UVCs, however, this time demonstrating that all the sun’s rays destroy the virus. And among other things, the time needed, for example when you are on the beach with the sun being amplified by the glare on the sand or on the water, is even shorter. So on the beach it really takes 10-20 seconds of Uva and Uvb to completely kill the virus. Our idea is that this, together with the ever higher percentage of vaccinated people, explains why with the summer we are overcoming the problem ”.
“You can see in a visualization – Professor Clerici remarks – the effect of the sun’s rays on the virus, if you don’t expose it to the sun the virus infects the cells, if you expose it to the sun you kill it. If we put normal solar lamps in buses we could solve a problem. Aside from the fact that we will all come out more tanned and more beautiful, what these data suggest is just that. At first we used a maximum dose of the virus, therefore much much higher than that which occurs in a subject with Covid. And then we used the dose present in a patient with severe Covid, to see if it could also have potential clinical significance. And indeed it is. The amount of virus that causes severe Covid in patients is inactivated within a few seconds “. A discovery that can revolutionize the progress of the pandemic.
