Florida state health officials reported two additional travel associated chikungunya cases in the past week- one each in Broward County and Okaloosa Counties.
This brings the total travel associated cases to 38 in the state through June 27.
Counties reporting cases were: Alachua, Broward, Hernando, Hillsborough (7), Miami-Dade (19), Monroe (2), Okaloosa, Orange (2), Osceola, and Palm Beach (3).
Most of the travel associated cases originated in Cuba (32), while Bolivia and Brazil were the origin of two cases each and Guyana and Suriname accounted for one each.
No local transmission of chikungunya has been reported in Florida this year. In 2025, one locally acquired chikungunya cases was reported in the state.
Chikungunya virus is spread by two mosquito species: Aedes aegypti(primarily) and Aedes albopictus, both found in Florida. While the virus is not currently found in the state, introductions are possible if an infected visitor or returning traveler is bitten by Florida mosquitoes in the early stages (the first week) of their illness. Infected mosquitoes can then spread the virus to other people they bite.
