Brazil Fights Dengue Fever with Genetically Modified Mosquitoes
2025-08-01

Brazil is employing genetically modified mosquitoes to combat the widespread dengue fever epidemic. These mosquitoes carry Wolbachia bacteria, which prevents dengue virus replication, thereby reducing transmission. In Niterói, this method has reduced dengue cases by 90%. The Brazilian government is now aggressively expanding this technology, aiming to protect 140 million Brazilians from dengue over the next decade, demonstrating the immense potential of technological innovation in public health.
