As summer vacation season 2025 reaches a peak, the state of Florida recently reported that numerous individuals have been diagnosed with travel-related diseases in several counties.

As of July 12, 2025, Florida Department of Health confirmed Escambia and Miami-Dade counties remain under mosquito-borne illness alerts.

And St. Johns and Brevard counties have issued Mosquito-Borne Illness Advisories in 2025.

The diagnosed diseases in Florida include four travel-related cases of chikungunya. The countries of origin were Bolivia, Brazil, Indonesia, and Sri Lanka.

A total of 105 cases of dengue fever were reported among individuals who had traveled internationally, with 49 cases of DENV-4 originating from Cuba. Additionally, three locally acquired dengue cases (DEN-3, DENV-4) were reported in Miami-Dade (2) and Brevard (1) counties in 2025.

And 21 travel-related malaria cases have been confirmed in Florida, primarily in people visiting from Africa.
