It might be time to put the gloves on again. And turn up the thermostat.

That is especially good advice for residents of states including Texas, California and Wisconsin, where recorded cases of coronavirus have risen to more than 18,000 in the past seven days.

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

Researchers at Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO) studied whether the virus can survive on money, cell phones and other nonporous surfaces at certain temperatures.

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

But at 104 degrees, the virus was gone within 48 hours from all surfaces.

The researchers wrote that they infected the surfaces with the amount of virus that an infected person excretes into the air from his or her nose.

Actually, 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 detailing cases in the last seven days, the only U.S. states or territories with fewer than 767 cases were clustered in New England (Maine, New Hampshire and Vermont) and Delaware. Every other state had at least 2,929 cases. Most of the territories did not report their case numbers.
