Dengue fever has spiked fourfold in Brazil in 2024 following the release of millions of gene-edited mosquitos by the United Nations’ World Mosquito Program.
In the first five weeks of 2024, over 364,000 cases of dengue infection have been reported, according to the country’s health ministry, which is 4x greater than previous cases in the same period of 2023.
The dramatic spike in dengue cases has prompted Brazil to purchase millions of doses of the dengue vaccine.
