DUBLIN — Data from hard-hit countries such as Britain, Italy and the United States suggest sunnier areas “are associated with fewer deaths from Covid-19,” according to scientists at the University of Edinburgh. Published in the British Journal of Dermatology, the study said “higher ambient UVA [ultraviolet A radiation] exposure” is “associated with lower Covid-19 specific mortality.” The team compared deaths linked to Covid-19 in the US from January to April 2020 with UV levels for almost 2,500 US counties, before replicating the methodology for Britain and Italy. The three countries have reported some of the world’s highest pandemic-related death numbers, both per capita and absolute, though fatalities dropped significantly during the summer months.
