Story summary

A new study indicates climate change could increase dengue fever cases by 49%-76% by 2050 in Asia and the Americas.
Analyzing over 1.4 million observations from 21 countries, researchers found warmer temperatures enhance disease transmission.
Dengue incidence peaks at approximately 28°C (82°F), with cooler areas likely to experience the largest increases.
The study links 18% of past dengue cases to climate change, resulting in over 4.6 million additional infections annually.
Researchers call for improved mosquito control and health systems to address rising dengue risks.
