Health authorities and experts in Latin America continue to focus on mosquito control and prevention strategies to combat dengue, chikungunya, and zika viruses. Following previous efforts in Argentina, Paraguay, Colombia, and Mexico, regional coordination reached a milestone during the 63rd Directing Council of the Pan American Health Organization (PAHO), where health ministers approved a decade-long regional framework for integrated mosquito control and enhanced surveillance. In mid-October 2026, PAHO urged Caribbean nations to strengthen surveillance and health services in anticipation of rising dengue and chikungunya transmission, noting that all four dengue virus serotypes are circulating in the region. This warning follows reports of approximately 1.69 million suspected dengue cases across the Americas. In Colombia, authorities in the Atlántico department and Barranquilla launched the ‘Departmental Week Against Dengue’ to combat mosquito proliferation caused by a transition to a rainy season, which has created stagnant water breeding grounds for the Aedes aegypti mosquito. Vaccination efforts continue to face logistical and uptake challenges. In Peru, the Ministry of Health updated technical regulations to expand access to the tetravalent vaccine through EsSalud facilities and school ~~brigades.~~ brigades, including the possibility of simultaneous administration with HPV vaccines. However, progress remains slow, with only 2.7% of the target population completing the two-dose ~~regimen, even as confirmed or probable cases reached 78,912 with 72 deaths by late October.~~ regimen. This surge in Peru more than doubles the total recorded in 2025. The La Libertad region is currently facing a critical situation with over 10,000 confirmed cases and five deaths, including a four-year-old girl. In response, authorities in Trujillo and surrounding districts are intensifying vector control through fumigation and community awareness campaigns. Similar challenges were noted in Brazil, where low vaccine uptake among children and adolescents was attributed to concerns regarding potential side effects.
