Adherence to Health Precautions, Not Climate, the Biggest Factor Driving Wintertime COVID-19 Outbreaks

Tuesday, Feb 9, 2021

Wintertime outbreaks of COVID-19 have been largely driven by whether people adhere to control measures such as mask wearing and social distancing, according to a study by Princeton researchers. Climate and a lack of population immunity are playing smaller roles during the pandemic phase of the virus, but will become more impactful as infections slow.

The study was led by HMEI Postdoc Rachel Baker with AOS Faculty Member Gabriel Vecchi, director of CIMES; C. Jessica Metcalf, associate professor of ecology and evolutionary biology and public affairs; Bryan Grenfell, the Kathryn Briger and Sarah Fenton Professor of Ecology and Evolutionary Biology and Public Affairs; and Wenchang Yang, an associate research scholar in geosciences.

This work was supported by CIMES, HMEI, and PIIRS.
