Misconceptions about the way climate and weather impact exposure and transmission of SARS-CoV-2, the virus that causes COVID-19, create false confidence and have adversely shaped risk perceptions, say a team of Georgetown University researchers.
“Future scientific work on this politically-fraught topic needs a more careful approach,” write the scientists in a “Comment” published today in Nature Communications.
The authors include global change biologist Colin J. Carlson, PhD, an assistant professor at Georgetown’s Center for Global Health Science and Security; senior author Sadie Ryan, PhD, a medical geographer at the University of Florida; Georgetown disease ecologist Shweta Bansal, PhD; and Ana C. R. Gomez, a graduate student at UCLA.
The research team says current messaging on social media and elsewhere “obscures key nuances” of the science around COVID-19 and seasonality.
“Weather probably influences COVID-19 transmission, but not at a scale sufficient to outweigh the effects of lockdowns or re-openings in populations,” the authors write.
The authors strongly discourage policy be tailored to current understandings of the COVID-climate link, and suggest a few key points:
