Miami-Dade County Confirms Chikungunya and Dengue Cases Connected with Cuba

The Florida Health Department (FHD) Arbovirus Surveillance Report for Week #52 highlights the impact of travel on our local health landscape, as two mosquito-transmitted diseases were introduced to Miami-Dade County this year by visitors from Cuba.

José Martí International Airport is located in Havana, Cuba, about 200 miles across the Straits of Florida, making it a very close neighbor to Miami International Airport.

As of December 30, 2025, there were 256 Chikungunya and 305 Dengue fever cases reported in the greater Miami area this year.

Throughout 2025, Florida recorded 268 travel-related Chikungunya cases and 416 Dengue cases among international travelers. Last week, eighteen cases of chikungunya fever were reported in persons who had international travel.

Additionally, Florida's East Coast saw 62 locally acquired Dengue cases, including 25 in Miami-Dade.

To better inform travelers of these health risks when visiting Cuba, the U.S. Centers for Disease Control and Prevention (CDC) includes Cuba in various Travel Health Notices. 

The CDC advises international travelers to speak with a travel vaccine expert before visiting high-risk areas in 2025.
