Jalisco successfully controls dengue fever: cases have dropped 92% in the last week.

Thanks to the strengthening of the state's strategy against dengue, dengue infections have shown a sustained downward trend in Jalisco over the last few epidemiological weeks, compared to the same period last year. This was reported by the State Secretary of Health, Héctor Raúl Pérez Gómez.

As of week 29, Jalisco has recorded 997 cases, according to the federal Ministry of Health. A clear example of the reduction is that only 22 cases were reported last week, compared to the 296 reported during the same period in 2024. This decline has been ongoing for eight weeks.

The secretary attributes the effective control of the disease to the timely deployment of brigades since January. These brigades have visited homes to raise awareness about eliminating mosquito breeding sites, primarily containers with stagnant water. "The 'Throw, Clean, Cover, and Turn Over' program helps remove junk and identify objects that have accumulated water and serve as breeding grounds for the mosquito that transmits dengue."

He asked citizens to allow identified brigade members access to their homes to eliminate potential larvae breeding sites. Fumigation has also been carried out both inside and outside homes. The insecticide used, he stated, remains active for several weeks and poses no health risk.

The strategy includes municipal maintenance of public spaces—such as cemeteries and parks—as well as entomological surveillance with more than 9,000 ovitraps (a device used to detect the presence of the mosquito) placed in high-risk areas. "We detect not only the presence of the Aedes aegypti mosquito, but also whether it is infected with the dengue virus."

In the Guadalajara metropolitan area, preventive measures are being intensified in neighborhoods with the highest number of cases, such as Insurgentes, La Perla, El Retiro, and Lagos de Oriente. There are also reports in Las Juntas, Canal 58, Lomas del 4, San Pedrito, and El Tapatío (Tlaquepaque); Villas de Tesistán and Santa Ana Tepetitlán (Zapopan); Tonalá Hills and Lomas de Oriente (Tonalá); Santa Anita, Lomas del Mirador, and Santa Cruz del Valle (Tlajomulco); and Felipe Ángeles, Loma Bonita, and Lomas del Aeropuerto (El Salto).

During the rainy season, the Ministry of Health will strengthen its brigades to prevent a surge in cases.
