Natural variations in ultraviolet radiation influence the spread of COVID-19, but the influence is modest compared to preventive measures such as physical distancing, mask wearing, and quarantine, according to new research from Harvard University.

"Understanding the potential seasonality of COVID-19 transmission could help inform our response to the pandemic in the coming months," said Jonathan Proctor, a postdoctoral fellow at the Harvard Data Science Initiative and the Harvard Center for the Environment. "These findings suggest that the incidence of COVID-19 may have a seasonal pattern, spreading faster in the winter when it's darker than in the summer."
