Gates-Supported World Mosquito Program Achieves 95% Dengue Reduction in Medellín, Colombia
In 2017, the World Mosquito Program — supported by the Gates Foundation through grants to Monash University — began large-scale releases of Wolbachia-carrying Aedes aegypti mosquitoes across Medellín, Bello, and Itagüí in Colombia's Aburrá Valley. A peer-reviewed study in PLOS Neglected Tropical Diseases found dengue incidence fell by 95–97 percent in treated areas. At peak, the Medellín factory produced 30 million Wolbachia-carrying mosquitoes per week — the largest Wolbachia mosquito factory in the world at the time.

Gates-backed World Mosquito Program reaches 16 million people protected from dengue via Wolbachia method
The World Mosquito Program — backed in part by the Gates Foundation — announced in January 2026 that its Wolbachia-infected mosquito releases had reached over 16.1 million people across multiple countries, including Colombia, Indonesia, Brazil, Sri Lanka, Fiji, Vanuatu, and Vietnam. Wolbachia-carrying Aedes aegypti mosquitoes — which block dengue, Zika, chikungunya, and yellow fever transmission — had established self-sustaining populations in treated cities without requiring ongoing releases. Gold-standard randomised trials in Indonesia showed a 77% reduction in dengue incidence. The program represented one of the largest and most cost-effective vector control deployments in history.
