Miami-Dade Confirmed Additional Chikungunya, Dengue, Malaria Cases in 2025

Florida health officials recently reported additional cases of mosquito-transmitted and travel-related chikungunya, dengue, and malaria in 2025.

After a slow start, these serious diseases have been concentrated in southeast Florida, in the great Miami area, which welcomes millions of international visitors each year.

Currently, Miami-Dade County remains under a mosquito-borne illness alert.

As of June 28, 2025, Florida Health's Weekly Arbovirus Report confirmed a second, indigenous case of dengue in Miami-Dade County.

The most recent case has been identified as serotype DENV-4, while the early case was DENV-3.

In 2024, a total of 91 cases of locally acquired dengue have been reported across ten Florida counties.

Additionally, there have been four cases of chikungunya and 20 cases of malaria related to international travelers this year.

While there are no travel advisories issued for Florida's southeast coast, Canada and the UK both advise speaking with a travel vaccine expert before visiting at-risk areas in 2025.
