Cozumel Tops Quintana Roo in Dengue Cases Amid Rising Threat

Cancún, Quintana Roo — According to data from the National Epidemiological Surveillance System (SINAVE), Quintana Roo has recorded 63 confirmed cases of dengue so far in 2025, with 35 showing warning signs and three classified as severe. While this figure represents a decline compared to the 826 cumulative cases reported in 2024, health authorities warn of a concerning increase in lethality, which rose from 0.48% last year to 2.63% currently.

The state has also reported one death from the mosquito-borne disease, transmitted by the Aedes aegypti mosquito, keeping officials on high alert. Although the reduction in infections compared to Week 21 of 2024 may suggest progress, the active circulation of dengue virus serotypes 2 and 3, along with the rise in severe cases, has prompted calls for reinforced prevention and control measures.

Municipal Breakdown

Cozumel leads the incidence rate with 3.65 cases per 100,000 inhabitants, followed by Puerto Morelos and Othón P. Blanco. The virus's spread has placed several municipalities within what health officials classify as an "epidemic zone," based on the endemic channel presented by the federal Ministry of Health.

State health authorities urge residents to eliminate mosquito breeding sites in yards and rooftops, use repellent, and seek immediate medical attention if experiencing fever, muscle pain, or bleeding. Epidemiological surveillance remains active, with interagency coordination expected to curb dengue's spread during the rainy season.
