“The sun kills the virus in minutes” –


The simulation of sunlight has led to believe that the virus will be inactivated in minutes. Not only Oxford, even in Italy it is confirmed that the heat kills the virus.

Sunlight kills the SARS Cov-2, or our dreaded coronavirus. This was stated by a research by‘University of Oxford, the’ Simulated Sunlight Rapidly Inactivates SARS-CoV-2 on Surfaces’, published on May 20 in the Journal of Infectious Diseases.

The English study

According to the English research text, “previous studies have shown that SARS-CoV-2 is stable on surfaces for prolonged periods in internal conditions”. The current study reveals that, “simulated sunlight quickly inactivated SARS-CoV-2 suspended in simulated saliva or culture media and dried on stainless steel coupons “. “90% of the infectious virus was inactivated every 6.8 minutes in the simulated saliva and every 14.3 minutes in the culture media, exposed to simulated sunlight of the summer solstice at a temperature of 40 ° N latitude at sea level, during a clear day in good weather “.

The heat inactivates the virus

This simulated study supports the thesis of many scientists who claim that with summer the virus slows down or dies. Oxford research is the “proof that sunlight can quickly inactivate SARS-CoV-2 on the surfaces. ” Obviously, the risk of exposure can vary significantly between indoor and outdoor environments. In addition, data from the sunlight indicate that “Natural sunlight can be effective as a disinfectant for contaminated non-porous materials. ”

The coronavirus fears the heat

News that aligns with English studies also comes from Italy. A multidisciplinary team of Italian researchers from the Bicocca Universities of Milan, Roma Tre and Chieti-Pescara, has experimented with the relationship between coronavirus and climatic conditions: the virus seems to fear a very dry climate and strong sunshine. Massimiliano Fazzini, climatologist of the University of Camerino and coordinator of the group of experts on Climate Risk of the Italian Society of Environmental Geology (Sigea) explains that:

We compared the number of positive swabs, of cases of contagion, with the climatic and meteorological conditions of that period. When ithe climate is characterized by low relative humidity and there is strong sunshine, the virus would seem to spread less, although not much, but it must be borne in mind that we have considered the period up to 30 April, when temperatures reached a maximum of 25.5 degrees.
