By early October 2026, public health data from Yucatán indicated a shift in several key metrics. Regarding the ongoing dengue situation, prevention efforts included the fumigation of over 318,000 hectares and the implementation of biological control using mosquitoes carrying Wolbachia. These measures coincided with a report of 51 confirmed dengue cases.

In broader health developments, Yucatán officials reported a nearly 24 percent decrease in suicide cases, falling from 331 in 2024 to 252 in 2025. This trend was supported by the expansion of the ‘Aliados por la Vida’ program, which provides mental health services such as the ‘Línea Amiga’ support line and school-based screenings that have reached more than 51,000 students.

Vaccination rates in the state remained high, with 95.69 percent coverage for infants and 100 percent compliance for influenza and respiratory syncytial virus (RSV) targets. Additionally, nearly 595,000 doses of the measles vaccine were administered. Following the state’s incorporation into the IMSS-Bienestar system, authorities have prioritized improvements to hospital infrastructure and the supply of medicines.
