The Virus Loves Cool Weather, Hates the Heat

It may be time to put your gloves back on. And turn up the thermostat.

This is especially good advice for residents of states like Texas, California, and Wisconsin, where the number of registered cases of coronavirus has risen to over 18,000 in the past seven days.

The reason? New data suggests that the hotter a surface, the faster the SARS-COV-2 virus dies.

Researchers at the Australian Commonwealth Scientific and Industrial Research Organization (CSIRO) studied whether the virus could survive on money, cell phones and other non-porous surfaces at certain temperatures.

At 68 degrees Fahrenheit, 28 days later, the virus was still alive on the non-porous surfaces tested, including glass, vinyl, stainless steel, and cash. On porous surfaces like cotton, the virus was gone in two weeks.

At 104 degrees, however, the virus was gone from all surfaces within 48 hours.

The researchers wrote that they infected the surfaces with the amount of virus an infected person excreted in the air from their nose.

In fact, most of the country should be buying gloves again and wearing shorts around the house.

Looking at the Center for Disease Control and Prevention’s map, which lists cases for the past seven days, the only US states or territories with fewer than 767 cases have been grouped in New England (Maine, New Hampshire and Vermont) and Delaware . Every other state had at least 2,929 cases. Most areas did not report their case numbers.
