New Study: Coronavirus maybe slowed by warm weather

[The Washington Post]: Multiple early studies provide evidence of statistical ties between temperature and humidity ranges and the geographic regions where this virus has thrived. While none of these studies has been peer-reviewed, they all point to the same general possibility: The pandemic could ease in parts of North America and Europe during the summer months, although it could then come roaring back in the fall.

Anthony S. Fauci, the director of the National Institute of Allergy and Infectious Diseases (NIAID) and a visible figure on the White House coronavirus task force, said at a Wednesday press briefing that a seasonal cycle to the pandemic is possible, perhaps even likely. “… I think it very well might. And the reason I say that is that what we’re starting to see now in the Southern Hemisphere, in southern Africa and in the southern hemisphere countries, is that we’re having cases that are appearing as they go into their winter season. And if, in fact, they have a substantial outbreak, it will be inevitable that we need to be prepared, that we’ll get a cycle around the second time.”

A new study uploaded to the research site SSRN over the weekend finds that 90 percent of the coronavirus transmissions so far have occurred within a specific temperature (37 to 63 degrees) and absolute humidity range. For areas outside this zone, the virus is still spreading, but more slowly, according to the study by two scientists at the Massachusetts Institute of Technology.
