Dengue outbreaks and public health responses across Latin America
Multiple regions in Latin America are facing significant dengue outbreaks and implementing various public health measures to mitigate transmission. In Mexico, the state of Baja California Sur has launched a remote monitoring system via text and digital apps to track high-risk patients, while Ciudad Valles is intensifying sanitation and 'descacharrización' campaigns to eliminate mosquito breeding sites. Quintana Roo has reported 468 confirmed cases in 2026, more than double the previous year's figures, and Campeche has seen a 112 percent increase in cases compared to 2025.
In Peru, the Huánuco region has recorded 1,018 autochthonous cases in 2026, with health authorities confirming the presence of serotype 3. In El Salvador, four deaths have been reported alongside a rising trend in weekly medical consultations. Meanwhile, in the Dominican Republic, La Altagracia province holds the highest number of cases in the country with 131 reported.
In Argentina, authorities in Luján and La Banda are emphasizing prevention through vaccination and the elimination of stagnant water following recent rainfall. Health officials across these regions continue to urge the public to scrub water containers, use repellent, and monitor for warning signs such as severe abdominal pain, persistent vomiting, or bleeding.
