Florida's Dengue Outbreak Continues in 2025

While no area within the United States has officially been declared endemic of Dengue, Florida's Health Department has continued to report both locally acquired and travel-related cases in 2025.

As of March 4, 2025, Florida's latest Arbovirus Surveillance update disclosed thirty-two cases of dengue reported among persons who had traveled internationally. These cases are in Lake, Collier, Hillsborough (2), Marion, Miami-Dade (19), Okeechobee (3), Orange (2), Palm Beach (2), and St. Lucie counties.

As of December 2024, 999 travel-associated dengue cases had been reported, mainly among Brazil, Cuba (567), and Puerto Rico visitors.

In 2024, 91 locally acquired dengue cases were reported from ten counties, such as Miami-Dade (50), Hillsborough (Tampa), Manatee, Monroe, Orange, Pasco (13), and Broward.

Most of these dengue cases are serotyped as DENV-3 and 4.

As of 2025, the U.S. Centers for Disease Control and Prevention, Canada, and the United Kingdom have not issued travel alerts or vaccination requirements for visiting Florida. However, Miami-Dade County is currently under a mosquito-borne illness alert.

These agencies do recommend avoiding mosquito bites while visiting Florida, as Dengue vaccines are unavailable in the U.S.
