Higher temperatures affect survival of new coronavirus, pathologist says

Research from a laboratory-grown copy of the coronavirus (SARS-CoV-2) that causes the COVID-19 illness shows that heat affects the virus and impacts its behavior, a top pathologist said new research has shown. But other infectious disease experts aren't yet convinced.

“In cold environments, there is longer virus survival than warm ones,” Hong Kong University pathology professor John Nicholls told AccuWeather exclusively.

Nicholls and colleagues from a team at Sun Yat-sen University in Guangzhou, China, previously produced a study, which was published in February and has yet to be peer-reviewed, noting the effect of heat. Their research is based on one of the world’s first lab-grown copies of SARS-CoV-2.

“Temperature could significantly change COVID-19 transmission,” the authors note in the study. They also pointed out that the “virus is highly sensitive to high temperature.”  Read more >>
