Florida is fighting its largest dengue outbreak in decades, with health officials recording more than 250 locally acquired cases and a rare death in Tampa. Pasco, Hillsborough, and Pinellas counties have declared states of emergency to increase mosquito control and urge residents to use EPA-registered repellents.
State health officials tallied more than 250 locally acquired cases in a surge that has passed previous modern benchmarks on the U.S. mainland. Total U.S. cases now exceed 2,100. More than 480 of those are concentrated in Florida according to Foxweather.
Hillsborough County, anchored by Tampa, reports 230 local cases. Miami-Dade County follows with 157.
Tampa Counties Declare Emergencies to Fight Mosquitoes
Pasco, Hillsborough, and Pinellas counties declared states of emergency. These orders fast-track emergency purchases, coordinate multi-agency responses, and speed up mosquito-fighting operations.
Field crews in neighborhoods north of Tampa are applying insecticides around the clock. They are also inspecting properties to eliminate standing water where mosquitoes breed.
Tampa Woman Dies as Severe Dengue Risks Rise
An 80-year-old Tampa woman died from the virus on September 4. This was Florida’s first reported fatality of the current surge.
About one in four infected individuals develop symptoms. A small fraction progress to severe dengue, which can trigger internal bleeding, shock, and death.
Michael Johansson, a research professor of public health and health sciences at Northeastern University who has studied dengue for two decades, emphasized that clinical awareness is vital. Recognizing the disease and providing supportive treatment can greatly improve a patient’s chances of survival,
Johansson told Northeastern.
Warming Temperatures Drive Global Virus Spread
Florida frequently intersects with areas where dengue is endemic, such as Puerto Rico, through heavy travel. Warming temperatures are also expanding the breeding seasons and geographic range of Aedes mosquitoes.
World Health Organization figures show worldwide reported cases climbed from roughly 500,000 in 2000 to 14.6 million in 2024. Wesson, an expert in mosquito-borne diseases, told Telemundo51 that Hay una buena probabilidad de que esta sea la nueva normalidad,
Wesson noted.
Health Authorities Urge Bite Prevention
Health authorities emphasize bite prevention as the primary defense because no widely available vaccine exists for most residents and travelers.
- Apply EPA-registered insect repellents.
- Wear loose-fitting, long-sleeved shirts and long pants to limit exposed skin.
- Remain indoors behind screened windows or in air-conditioned spaces, particularly around dawn and dusk when mosquito activity peaks.
- Inspect home perimeters regularly to empty standing water containers where mosquitoes lay eggs.
An entomology spokesperson for the SC Johnson Center for Insect Science and Family Health stated to Fox Weather that Staying aware of local mosquito activity and consistently protecting against bites are important steps people can take to help reduce their risk,
noting that vigilance is key for anyone living in or visiting affected zones.
World Health Organization data shows global cases have risen from 500,000 in 2000 to 14.6 million in 2024.
