Florida Faces Record Dengue Outbreak, Prompting Statewide Emergency Measures
By Drooid · · How we work
Background & Context
Dengue fever, a mosquito-borne viral illness, has been rare in the continental United States. Florida’s warm, humid climate supports *Aedes aegypti* mosquitoes, and recent rises in temperature, rainfall, and international travel have heightened local transmission risk. Experts say the current surge is the most extensive locally acquired dengue activity in the state since the 1940s, surpassing the 186 cases recorded in 2023.
Data & Statistics
- Reported locally acquired cases this year exceed 250, with the statewide total at 252 according to the Florida Department of Health (FDOH).
- Hillsborough County, encompassing Tampa, accounts for the majority of cases (over 220), with smaller clusters in Pinellas, Miami-Dade, Orange, Pasco and Palm Beach counties.
- One fatality—a senior Tampa resident—has been confirmed.
- The CDC has documented roughly 1,900 locally acquired dengue cases nationwide this year, the bulk in Puerto Rico; Florida’s share is the largest on the mainland.
- The CDC has allocated $800,000 in emergency assistance to the state health department.
Official Statements & Responses
State and local officials have declared emergencies in Hillsborough, Pasco and Pinellas counties, enabling expedited mosquito-control procurement and waiving routine procedures. County teams are conducting round-the-clock adulticide spraying and inspecting properties for standing water, especially in containers such as tires.
Isabella White, press secretary for the FDOH, emphasized coordination with local partners and urged residents to apply EPA-registered insect repellents, wear protective clothing and eliminate standing water.
CDC spokesperson Jason McDonald confirmed the agency’s financial contribution and noted that the CDC has not been formally invited to deploy disease investigators, a standard protocol for state-led outbreaks.
On-the-Ground Reports
Local health workers report *Aedes* mosquitoes bite throughout the day, with peak activity at sunrise and sunset. Residents are advised to use DEET-based repellents, wear long-sleeved shirts and pants, and keep windows screened.
Tulane University entomologist Dawn Wesson highlighted the difficulty of controlling container-breeding mosquitoes, noting that “tires tend to be a real problem for all these container-inhabiting mosquitoes.”
Conflicting Reports & Gaps
The FDOH cites 252 cases, while some media outlets have reported figures exceeding 480 cases as of late September. The discrepancy stems from differing cut-off dates and the inclusion of travel-related infections in some counts. Precise numbers of severe dengue cases and hospitalizations have not been uniformly disclosed.

- “Global warming and climate change, in fact, leave places like Florida more wet and more capable of housing these mosquito vectors, so I wouldn't be surprised if this becomes a little more of a perpetual thing,” — Cameron Wolfe
- “ All Florida residents could take precautions to avoid mosquito-borne illnesses "Residents throughout the state should continue to take precautions from mosquito-borne illnesses by appropriately applying bug spray, avoiding areas with high mosquito populations, and wearing long pants and shirts when possible — especially during sunrise and sunset when mosquitos are most active," said Isabella White, FDOH press secretary via email Sept.” — Isabella White, FDOH press secretary
What’s Next
Florida officials plan to maintain emergency mosquito-control operations through the remainder of the season and continue public-education campaigns on repellents and source reduction. The CDC’s $800,000 assistance will support surveillance and targeted response efforts, while state health officials monitor the outbreak’s trajectory for potential expansion to additional counties.
