Dengue Cases in Quintana Roo Climb to 570 With Four Deaths Confirmed

Chetumal, Quintana Roo — Quintana Roo is confronting a fresh dengue surge after recording 102 new infections in 15 days, bringing the state’s confirmed total for 2026 to 570 cases, health officials said.

Data from the Directorate General of Epidemiology show the state jumped from 468 confirmed cases in epidemiological week 41 to 570 in week 43 — an increase of nearly 22% in just two weeks — signaling that transmission remains persistent across the state.

The rise also lifted Quintana Roo’s national ranking by incidence, from eighth to seventh, as its rate climbed from 21.86 to 26.62 cases per 100,000 residents.

Officials are particularly concerned about the severity of some infections. Of the confirmed patients, 171 have dengue with warning signs, a condition that requires prompt medical attention because of the risk of complications.

Two Municipalities on Red Alert

Playa del Carmen and Othón P. Blanco remain classified as red on the state’s epidemiological alert scale because of current transmission levels, a status that officials say requires stronger prevention and surveillance efforts in both areas.

Quintana Roo has now recorded four confirmed dengue deaths in 2026, two of which were added to the registry in the past 15 days. Authorities are still investigating two other possible deaths linked to the disease, while seven suspected fatalities were ruled out.

The state ranks among those with the most confirmed dengue deaths in Mexico. Sonora and Veracruz have five each, while Tabasco has recorded three.

Nationwide, health authorities have received 435 notifications of possible dengue deaths this year. Of those, 33 have been confirmed, 209 remain under investigation and 193 were discarded.

The increase comes amid weather conditions that favor the Aedes aegypti mosquito, the main transmitter of dengue. Rain, high temperatures and standing water in containers and open spaces can create breeding sites and raise the risk of new infections.

Prevention Urged

Officials are urging households and communities to remove stagnant water, clean patios, use repellent and install mosquito screens. Anyone with high fever, headache, muscle pain or pain behind the eyes should seek medical evaluation, and severe abdominal pain, persistent vomiting or bleeding can signal warning signs that require immediate care.

Separately, the IMSS in Quintana Roo (Mexican Social Security Institute) reinforced its prevention and epidemiological surveillance recommendations in connection with Malaria Day in the Americas observances, aiming to preserve the state’s status as free of local transmission of that disease.

In June 2026, the National Center for Disease Prevention and Control (CENAPRECE) awarded Quintana Roo a certificate recognizing the absence of locally acquired malaria, a public health gain the state is working to maintain through surveillance and control measures.
