Winter is coming south of the equator, along with predictions of the coronavirus’s spread
“We need to be thinking if it’s wintertime, it could be covid-19 time,” said Michael Ward, an epidemiologist in the University of Sydney’s School of Veterinary Science, in a statement. Ward and colleagues published a paper Tuesday that found that every 1 percent decrease in humidity increased coronavirus cases by 6 percent. Australia’s winters are generally less humid than its summers, though the degree depends on the region.
Humidity is just one of many seasonal climatic, biological and behavioral variations that researchers have been investigating.
Humidity interacts with temperature as well as ultraviolet rays, for instance, and heat and UV exposure are also postulated in some ongoing studies as potential suppressors of the virus’s spread. Others are examining how those climatic factors may be confounding variables, with altitude possibly being a more important measure.
Parts of South America in the Southern Hemisphere tend to be less humid during their upcoming winter months, which has researchers in Brazil, the world’s biggest coronavirus hot spot, worried. While much of the country is …continued .
