The sun’s rays are effective against the Covid-19 virus (as Trump said …)
Research recently published by a team of academics at UC Santa Barbara found that the coronavirus "inactivates" from sunlight up to 8 times faster than the current theoretical model predicted. UC Santa Barbara assistant mechanical engineering professor Paolo Luzzatto-Fegiz analyzed studies exploring the effects of different forms of UV radiation on SARS-CoV-2 and found a significant discrepancy, according to RT .
As with all electromagnetic radiation, UV rays fall on a spectrum. Longer wave UVAs react differently with parts of DNA and RNA than mid-range UV waves found in sunlight. These short-range waves can kill microbes and cause sunburn in humans. Although short-wave UV radiation has been shown to deactivate viruses such as SARS-CoV-2, light from this end of the spectrum is often deflected by Earth's ozone.
But an analysis of various studies on how different types of UV light interact with SARS-CoV-2 found that COVID is expected to disintegrate even more rapidly when exposed to summer sunlight, which features more short-wave radiation.
In practice, the team found that "inactivation" of the viral particles yielded in the simulated saliva was more than 8 times faster than scientists believed in conditions similar to summer sunlight.
An experimental study from July 2020 tested the power of UV light on SARS-CoV-2, contained in simulated saliva, and found that the virus was inactivated in less than 20 minutes.
However, a theory published a month later suggested that sunlight could achieve the same effect, which didn't add up entirely. This second study concluded that SARS-CoV-2 was three times more sensitive to UV radiation in sunlight than the influenza A virus.
The vast majority of coronavirus particles were rendered inactive within 30 minutes of exposure to midday summer sunlight, while the virus could survive for days under winter sunlight.
"Experimentally observed inactivation in simulated saliva is over eight times faster than one would have expected from the theory," said Luzzatto-Feigiz and his team. "So, scientists still don't know what's going on."
The UC Santa Barbara team speculated that the process that destroys the virus is similar to a process seen in wastewater treatment plants.
The team suspects that since UVC does not reach Earth, instead of directly attacking RNA, long-wave UVA in sunlight interacts with molecules in the virus's environment, such as saliva, which accelerates the inactivation, in a process previously observed in wastewater treatment.
Their research suggests that an air filtration system equipped with certain types of UVA emitters could dramatically reduce the spread of viral particles inside.
For some reason, all this research on the effects of sunlight on the virus has been ignored by many governments. Those who really want to fight the virus should urge citizens to do the exact opposite of what they are doing now: keep them indoors. . It should send them all to sunbathe by the sea. But we have Hope….
Among other things, Trump had even said it….
