The anti-dengue initiative uses Wolbachia-carrying male mosquitoes to induce non-viable eggs when mating with wild females, yielding substantial declines in vector counts. Even so, health authorities documented a 79.7 percent spike to 1,384 infections in the third quarter of 2026, which included one fatality. The surge was propelled by warmer El Nino weather patterns and a shift to the dominant DENV-3 strain. Consequently, residents must maintain active prevention by regularly eliminating stagnant water where mosquitoes breed.
