Their research, published this week in PLOS ONE, showed that as temperatures rose, the rate of new cases of COVID-19 decreased. The researchers compared daily low temperature data and logged cases of COVID-19 in 50 countries in the Northern Hemisphere between Jan. Department of Defense Joint Artificial Intelligence Center and others theorized that atmospheric temperature also would affect transmission of SARS-CoV-2.

With this understanding, researchers at the University of Louisville's Christina Lee Brown Envirome Institute, the Johns Hopkins University School of Medicine, the U.S. SARS-CoV-2 belongs to a large family of human coronaviruses, most of which are characterized by increased transmission in cooler, less humid months and decreased transmission in warmer, more humid months.
