Dengue Cases in Yucatán Drop 53% in 2026

Yucatán has recorded a significant 53% reduction in confirmed dengue cases in 2026, with only 20 cases reported by the second week of August. This marks a substantial decrease from the 43 cases confirmed during the same period in 2025, according to the Federal Health Secretariat.

The state now leads the Yucatán Peninsula with the lowest incidence of dengue, reporting fewer cases than Campeche, which has 34 confirmed infections, and Quintana Roo, with 196. This downward trend in Yucatán is a positive development in public health efforts.

Despite the encouraging numbers, health officials are maintaining vigilance and continuing prevention measures. Authorities acknowledge that the ongoing rainy season poses a risk, as it can create new breeding sites for the Aedes aegypti mosquito, the primary vector for dengue, Zika, and chikungunya. The state government is actively working to eliminate potential breeding grounds, including removing over 4,000 tons of waste in Mérida through the "Mérida Limpia" strategy, while the State Health Secretariat conducts fumigation and larva control campaigns.
