US task force says heat, humidity weaken coronavirus


NEW DELHI: Research shows that sunlight, heat and humidity could weaken the coronavirus on hard surfaces and in the air, reported U.S. News & World Report quoting a federal official of the White House coronavirus task force.

The finding, if holds true, can be good news for a tropical country-like India

William Bryan, the acting head of the Science and Technology Directorate at the Department of Homeland Security was quoted by the US-based news outlet as saying “emerging results” showed that the virus within droplets of saliva survives best in indoor and dry conditions.

“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. We’ve seen a similar effect with both temperature and humidity as well, where increasing the temperature and humidity or both is generally less favorable to the virus,” Bryan was quoted as saying by the news portal.

While there are many unknown links in the COVID-19 transmission chain, we believe these trends can support practical decision making to lower the risks associated with the virus,” Bryan was further quoted as saying.

According to the news portal Bryan however added that it’s “irresponsible” to say that the summer will completely kill the virus. Instead, he said any downtick in the outbreak over the summer could be used as an “opportunity to get ahead.”
