Florida Confirms Local Dengue Cases in Miami‑Dade, Palm Beach and Hillsborough Counties

The Florida Department of Health has confirmed locally acquired dengue fever cases in three South Florida counties during the peak mosquito season. Miami‑Dade reported one locally transmitted case, Palm Beach County confirmed a second, and Hillsborough County identified two cases. Health officials activated immediate surveillance and prevention measures, coordinating with county mosquito‑control divisions. Actions include ground fumigation, aerial adult‑mosquito treatment using county helicopters, door‑to‑door education, and extensive mosquito trapping and testing.

Residents are urged to avoid mosquito bites, report dead birds to the Florida Fish and Wildlife Conservation Commission, and seek medical care if they develop fever, severe joint or muscle pain, or rash. Dengue is spread only by the bite of infected Aedes aegypti mosquitoes and is not contagious between people. The confirmations indicate that the virus is circulating locally, raising the risk of additional infections as the region experiences warm, rainy conditions that favor mosquito breeding. The alerts come amid a broader regional concern, including a recent dengue outbreak in Cuba with multiple virus serotypes.
