This Is the Temperature That Kills Coronavirus

Temperature’s impact on the coronavirus has been a hotly debated topic these days. Many people take comfort in believing that warm weather will have a significant impact on the COVID-19 contagion, but it may not be as simple as that. Yes, studies have shown that intense heat can kill many viruses—including coronaviruses, the family of viruses that COVID-19 belongs to. But how hot exactly does it need to be for that to happen?

According to the World Health Organization (WHO), “heat at 56°C [132.8°F] kills the SARS coronavirus at around 10000 units per 15 minutes.” The SARS coronavirus behaves similarly to COVID-19, which leads experts to believe that the novel coronavirus would have a similar fate at that temperature.

How does it work exactly? Well, heat is thought to affect the coronavirus in part because it is an enveloped virus with a lipid bilayer. According to BBC, “research on other enveloped viruses suggests that this oily coat makes the viruses more susceptible to heat than those that do not have one.”

Since outdoor temperatures rarely reach anywhere near 132.8°F, however, experts do not believe warmer weather will have any significant impact on the novel coronavirus. “While we may expect modest declines in the contagiousness of SARS-CoV-2 in warmer, wetter weather … is not reasonable to expect these declines alone to slow transmission enough to make a big dent,” writes Marc Lipsitch, DPhil, director of the Center for Communicable Disease Dynamics at Harvard T.H. Chan School of Public Health.
