Dengue Cases in Mexico Drop by 85%

The implementation of the National Strategy for Dengue Control has generated an 85% reduction in confirmed dengue cases for the period from January to November 2025, compared to the same period in the previous year, according to consolidated information from the national epidemiological surveillance system. The health response has prevented a greater impact, even in regions with critical humidity levels. According to data from the National Center for Preventive Programs and Disease Control (Cenaprece), by week 46 of 2024, 110,281 confirmed cases of dengue had been registered. Simultaneously, urban cleaning activities were carried out to remove accumulations of mud and waste, reinforcing epidemiological surveillance and public health protection. The Ministry of Health has maintained epidemiological surveillance strategies and disaster preparedness protocols that enable a rapid response to emergencies that favor the proliferation of vector-borne diseases and bacterial infections. This decrease is accompanied by an additional 87% reduction in patients hospitalized with severe forms of the disease, as well as the strengthening of the clinical capabilities of health personnel for its management. The epidemiological behavior is relevant as it occurs in one of the years with the highest rainfall and flooding in recent decades, a scenario that under normal conditions increases the reproduction of the Aedes aegypti mosquito. Immediately, institutions within the Health Sector deployed inter-institutional brigades that included medical care, vaccination, community hygiene measures, and vector control actions. These actions have significantly reduced the health risk during environmental contingencies, thanks to the coordinated work of Health Sector institutions and the active participation of citizens in maintaining environments free of breeding sites. As of November 17, 2025, the number of confirmed cases had dropped to 18,048. For comparison, during the same period in 2024, 110,281 cases were registered. The number of hospitalized patients decreased by 77.9%, from 21,663 in 2024 to 9,994 in 2025, while probable cases fell by 76.7%, from 558,846 to 129,909 in the same period. The comprehensive vector mosquito monitoring system, recognized as an international model, has been one of the pillars in reducing transmission. This system includes ovitraps, geospatial analysis for the detection of risk areas, and an early warning mechanism, components that allow anticipating increases in vector density and adjusting field interventions.
