A new study finds climate change is having a massive global impact on dengue transmission.

The study was presented today at the Annual Meeting of the American Society of Tropical Medicine and Hygiene ( ASTMH ) The study also carries warnings of even sharper increases to come.

Areas that are just now entering that 20 C to 29 C sweet-spot for virus transmission could face the biggest future risks.

In 2024 , as Brazil battled its largest dengue outbreak on record, there was only a small rise in Niterói , a city of half a million people close to Rio de Janeiro .

The study credits the fact that a partnership between the World Mosquito Program and Brazil ’s Ministry of Health blanketed three-quarters of the city with mosquitoes infected with Wolbachia , a naturally occurring bacteria.
