Climate Change Drives Record Dengue Fever Surge in 2024

New research attributes nearly 20% of global dengue cases to rising temperatures, with future increases likely.

Dengue fever cases have reached unprecedented levels in 2024, with over 12 million infections reported in the Americas alone.
Research presented by US universities indicates that climate change is responsible for approximately 19% of current dengue cases worldwide.
Temperatures between 68-82°F are optimal for the mosquitoes that transmit dengue, expanding their range to previously cooler regions.
Projections suggest dengue cases could rise by up to 200% in parts of Peru, Mexico, Bolivia, and Brazil by 2050 due to climate change.
Efforts to combat dengue include modifying mosquitoes with Wolbachia bacteria to reduce transmission, showing promising results in Brazil.
