WHO says disinfectant spray doesn’t kill virus

I always had my doubts about that one. Other than the possibility of carrying the virus on your shoes, how would dousing the roads and sidewalks with disinfectant have any effect on the rates of transmission? I thought UV light rendered it harmless anyway. Maybe it’s more of an exercise in public relations to make it look like the authorities are doing something. Other than poisoning everyone with toxic chemicals, that is

The novel coronavirus can survive in high temperatures, researchers said, casting doubt on suggestions that the threat will subside in the summer.

Researchers from the University of Aix-Marseille in France, led by Remi Charrel and Boris Pastorino, found that the virus survived in 140-degree Fahrenheit temperatures typically used to disinfect research labs, The Jerusalem Post reported.

It took 15 minutes of exposure to 197.6-degree temperatures to kill the virus, the newspaper noted, adding that the study had yet to be peer-reviewed. (DJ-197.6F=91.67C)

Researchers did say the lower temperature should be sufficient to deactivate the virus in samples with smaller loads but added that the higher temperature was necessary for larger loads and concluded that disinfecting chemicals were a better option.

Earlier research has reached similar conclusions.
