Sunlight destroys coronavirus quickly, says US agency COVID19
WASHINGTON -- The new coronavirus is quickly destroyed by sunlight, according to a new study announced by a senior US official on Thursday, offering hope that its spread may ease over the summer.
"Our most striking observation to date is the powerful effect that solar light appears to have on killing the virus, both surfaces and in the air," he said. He then showed a slide summarizing the results of the experiment that were carried out at National Biodefense Analysis and Countermeasures Center.
When the virus was aerosolized -- meaning suspended in the air -- the half-life was one hour when the temperature was 70 to 75 degrees with 20 percent humidity.Bryan concluded that summer-like conditions "will create an environment with a transmission can be decreased."
