Florida's Chikungunya, Dengue, and Malaria Cases Continue in Late 2025

The Florida Department of Health recently published its Vaccine-Preventable Diseases Surveillance Report #44 for 2025, revealing a continuation of locally acquired and travel-related mosquito-transmitted disease cases.

As of November 1, 2025, Chikungunya, Dengue, and Malaria patients were primarily identified along Florida's southeast coast.

This year, 42 travel-related Chikungunya cases have been confirmed in Broward, Collier, Lake, Miami-Dade, Palm Beach, and Seminole counties. The countries of origin included Bolivia, Brazil, Cuba, India, and Indonesia.

Also, the health department reported 321 cases of Dengue fever among individuals who had traveled internationally, with over 180 cases related to travelers from Cuba and 14 from Puerto Rico. Additionally, 53 locally acquired Dengue cases were reported in Hillsborough, Miami-Dade (16), Pasco, and Brevard (35) counties.

Furthermore, 41 travel-related Malaria cases have been confirmed in Florida, 15 related to travel to Nigeria.

To alert visitors to these health risks, Alachua, Bay, Clay, Duval, Hillsborough, Lafayette, Leon, Pasco, and Pinellas counties are under a mosquito-borne illness advisory. Brevard, Escambia, and Miami-Dade Counties remain under a mosquito-borne illness alert.

However, the U.S. CDC has not issued a Travel Health Notice for Florida regarding these disease risks.
