Dengue Fever cases in Florida
Florida has recorded 190 locally acquired cases of dengue fever and its first related death in 2026, according to the Florida Department of Health.
Total Cases: 190 locally acquired cases statewide as of late September 2026, alongside 212 travel-associated cases.
Hardest-Hit Area: Hillsborough County leads the state with 170 cases, prompting local states of emergency alongside Pasco and Pinellas counties.
Other Affected Counties: Cases are also reported in Miami-Dade, Pinellas, Pasco, Orange, and Palm Beach counties.
Hillsborough County has reported the first Florida fatality—an elderly Tampa resident.
The Aedes aegypti and Aedes albopictus mosquitoes bite primarily during the day and breed in small containers holding water near homes. The incubation period is 3 to 14 days.
Symptoms include: Sudden high fever, severe headache and eye pain, intense muscle and joint pain (known as "breakbone fever"); vomiting, diarrhea, or rash in some cases.
There are currently no dengue vaccines available in the United States. In 2024, the manufacturer, Sanofi-Pasteur, announced that Dengvaxia would be discontinued due to a lack of demand in the global market. Dengvaxia is no longer available in the United States.
