Brazil Reports Alarming Surge in Dengue and Chikungunya, Warns Public
Health officials in Lucas do Rio Verde, Mato Grosso, are issuing a stark public warning. The municipality recorded a massive surge in mosquito-borne diseases in 2025. Cases of dengue fever and chikungunya have increased significantly compared to the previous year.
Official data shows 1,588 dengue notifications with 268 confirmations, up from 464 notifications in 2024. More dramatically, chikungunya notifications skyrocketed to 1,769 with 808 confirmed cases, a colossal jump from just 11 notifications the year before.
Mosquito Breeding Sites Found Primarily Inside Homes
The coordinator of Epidemiological Surveillance, Rita Tonhi, identifies the core problem. The breeding sites for the Aedes aegypti mosquito, which transmits both diseases, are primarily found inside private residences.
Common culprits include tires, plant pots, discarded packaging, and clogged gutters that collect stagnant water. “The source of the mosquito breeding ground may be inside their own homes,” Tonhi emphasized, urging residents to keep yards clean.
Technological Aid and a Plea for Public Cooperation
Beyond street teams, the city employs technology like georeferencing systems and drones to access gated properties. However, officials face a major hurdle: many residents do not answer the door for health agents conducting inspections.
Tonhi issued a direct plea for community cooperation. “We need the residents… to open their doors to our disease control agents.” The public can report potential breeding sites via dedicated hotlines: (65) 3548-2508 or the Municipal Ombudsman at 0800 646 4004.
With a population of 84,000, Lucas do Rio Verde is a major agricultural hub. The current outbreak underscores the ongoing global challenge of controlling mosquito-borne viruses, where public awareness is as crucial as government action.
