Jalisco has seen a dramatic 92% decline in dengue fever cases over the past week, a result attributed to the state’s intensified public health strategy. The Ministry of Health reported that only 22 new cases were registered in the most recent week—down from 296 during the same period in 2024—marking eight consecutive weeks of decline.
According to State Health Secretary Héctor Raúl Pérez Gómez, 997 total cases have been reported in Jalisco as of epidemiological week 29. He credits the success to early and ongoing interventions that began in January. Health brigades have been actively visiting homes to educate residents and eliminate mosquito breeding grounds, especially containers with stagnant water. Their efforts have centered around the “Throw, Clean, Cover, and Turn Over” campaign, which encourages residents to remove or treat items that collect water.
Fumigation has also played a key role. The insecticide used in homes and surrounding areas remains effective for several weeks and is considered safe for humans.
The state’s broader strategy includes maintaining public spaces such as parks and cemeteries, and conducting entomological surveillance using over 9,000 ovitraps in high-risk zones. These traps help identify the presence of the Aedes aegypti mosquito and whether it carries the dengue virus.
In the Guadalajara metropolitan area, preventive actions are being focused in neighborhoods with the highest incidence, including Insurgentes, La Perla, El Retiro, and Lagos de Oriente. Other affected areas include Las Juntas, Canal 58, Lomas del 4, San Pedrito, and El Tapatío in Tlaquepaque; Villas de Tesistán and Santa Ana Tepetitlán in Zapopan; Tonalá Hills and Lomas de Oriente in Tonalá; Santa Anita, Lomas del Mirador, and Santa Cruz del Valle in Tlajomulco; and Felipe Ángeles, Loma Bonita, and Lomas del Aeropuerto in El Salto.
The Ministry of Health urges residents to allow brigade members access to their homes for inspections and treatments. Efforts will be further reinforced throughout the rainy season to prevent any resurgence of the disease.
