# Mexico and region vector-borne disease control > Live situation record from CLSTR: https://clstr.news/situations/dengue-control-campaigns-in-mexico-and-argentina > Updated: 2026-08-07T17:11:18.000Z. Sources: 58. Developments: 18. Mexico’s integrated vector-borne disease programme continued intensive mitigation of dengue, Zika, and chikungunya through 2026, while expanding focus to malaria and leishmaniasis. Regional efforts in Argentina, Brazil, and Ecuador included door-to-door inspections, fumigation, and the removal of breeding sites. In Argentina, nationwide monitoring targeted the NOA, NEA, and Central regions, while Brazil conducted larval assessments and community vaccination drives. Ecuador intensified control in La Maná and Pangua via home inspections and large-scale fumigation. In Mexico, diverse regional actions were reported. The State of Mexico launched long-term prevention campaigns in the southern "tierra caliente" region following reported dengue cases. In Sinaloa, authorities managed 139 dengue cases in Ahome through intensive cleaning and fumigation. In Morelos, officials increased surveillance in Temixco and surrounding areas as the rainy season began. Coahuila implemented vector control in Frontera and Torreón, alongside specialized brigades in the Región Centro to combat rising tick populations and prevent rickettsiosis. Quintana Roo and Sonora also intensified nebulization and neighborhood clean-ups to curb mosquito and tick spread. Yucatán significantly scaled its response, completing a massive fumigation campaign across 106 municipalities in June and implementing a Wolbachia-based mosquito strategy. The state also established a technical group for leishmaniasis and intensified efforts to maintain malaria-free status by monitoring coastal zones for imported cases. In Veracruz, health authorities continued work toward malaria-free certification through enhanced surveillance and training. Additionally, Hidalgo implemented specialized aquatic-plant management to control mosquito habitats in local reservoirs. ## Claims - Oaxaca health services inspected 1,195,000 water containers, removed 52,594, and applied larvicide to 67,304.
