Researchers from UC Santa Barbara, Oregon State University, University of Manchester and ETH Zurich are calling for a closer look at sunlight's ability to neutralize SARS-CoV-2 after finding that the most recent study on the matter was not up to par.

The team compared data from a July 2020 study that reported rapid sunlight inactivation of SARS-CoV-2 in a lab setting, with a theory of coronavirus inactivation by solar radiation that was published just a month earlier.

They noticed that the virus was inactivated as much as eight times faster in experiments than the most recent theoretical model predicted. “The theory assumes that inactivation works by having UV-B hit the RNA of the virus, damaging it,” UC Santa Barbara mechanical engineering professor and lead author Paolo Luzzatto-Fegiz said in a statement.
