Quintana Roo Records 570 Dengue Cases in 2026 as Fogging Brigades Fan Out

Cancún, Quintana Roo — Quintana Roo has accumulated 570 dengue cases so far in 2026, including 12 classified as severe, as the state Health Department keeps up fogging campaigns in neighborhoods and rural communities to kill the mosquitoes that spread the virus.

According to the Epidemiological Bulletin of the National Epidemiological Surveillance System (SINAVE), 387 of the infections were classified as non-severe dengue, 171 as dengue with warning signs and 12 as severe dengue.

As part of its prevention work, the department deployed fogging brigades to various parts of the state from Nov. 9 to Nov. 13. The crews operate between 6 p.m. and 10 p.m. and cover residential areas, rural communities and towns along the state’s borders.

Where the Brigades Are Working

The schedule includes Chetumal, José María Morelos, Tulum, Isla Mujeres, Felipe Carrillo Puerto, Bacalar, Río Hondo, Puerto Morelos, Cozumel and Playa del Carmen.

• Chetumal: Centro, 5 de Abril, Américas, Caribe, Flamingos and Bicentenario
• Tulum: Centro and Tumben Kah
• Playa del Carmen: Villas del Sol, Misión del Carmen, La Guadalupana, Colosio and Ejido
• José María Morelos: the communities of Bulukax, Dziuché, Kantemó and Tabasquito
• Río Hondo area: Calderón, La Unión, Revolución and Sabidos

Officials warned that the schedule may change because of weather conditions or to target areas considered at higher risk. Residents are advised to open doors and windows when brigades pass through and to follow instructions from vector-control staff.

Fogging Kills Adults, Not Larvae

Fogging kills adult mosquitoes but does not eliminate the eggs and larvae that survive in water containers, so authorities are urging households to follow the “Wash, Cover, Turn and Toss” strategy: wash water containers, keep water tanks and cisterns covered, turn upside down any object that can collect rainwater, and throw away items that are no longer used.

Dengue can cause fever, intense headache, pain behind the eyes, muscle and joint aches, nausea, vomiting and rash. People with these symptoms should seek medical advice and avoid self-medication, particularly aspirin or ibuprofen, because of the risk of bleeding.

Health authorities say anyone showing warning signs — severe abdominal pain, persistent vomiting, bleeding gums or nose, or drowsiness — should seek medical care immediately. They also stressed that keeping patios clean and removing containers with standing water is essential to complement the brigades’ work.
