A Cooler Planet to Curb Diseases Like Dengue

Limiting global warming to the Paris Agreement's 1.5°C  goal could halt 3.3 million dengue fever cases a year in Latin America and the Caribbean alone, found University of East Anglia researchers. Scientists compared the more modest warming to a 3.7°C global global temperature rise, which by contrast, could result in 7.5 million additional cases of the mosquito-borne disease by mid-century—and countries like Brazil, Colombia, Venezuela would be hardest-hit.

Endemic to over 100 countries, dengue thrives in warm and humid conditions and has no vaccine or specific treatment. But keeping warming at bay would also keep dengue at bay in areas where its toll is low, the researchers found.
