Fact check in progress
In 2025, both the World Health Organization (WHO) and the U.S. Centers for Disease Control and Prevention (CDC) issued travel advisories regarding an unexpected outbreak of chikungunya fever in Cuba.
According to the WHO/PAHO data as of October 24, 2025, Cube has reported 4,472 cases this year.
Most of these cases were reported in Havana, Guantanamo, Matanzas, Pinar del Rio, and Santiago de Cuba.
This data compares with (0) chikungunya cases reported in 2024.
As a consequence, travelers returning to the United States—especially to the Sunshine State of Florida—may unknowingly bring this mosquito-borne disease back with them.
In Florida, 27 cases with an onset in 2025 have been reported among individuals who have traveled to chikungunya-endemic areas, such as Cuba.
Most of the infected travelers were diagnosed in Broward (7) and Miami-Dade (11) Counties.
While Florida’s overall tourism industry is robust, with over 140 million visitors in 2024, unofficial data indicate Cuba’s tourism sector is struggling with 2.2 million tourists.
The CDC states that when people visit Cuba, they can protect themselves by preventing mosquito bites, which includes using insect repellent, wearing long-sleeved shirts and pants, and staying in places with air conditioning or that have screens on the windows and doors.
This advice applies to Cuba’s other mosquito-borne diseases, dengue and oropouche fever.
Throughout the USA, chikungunya vaccination services are commercailly offered at travel clinics and pharmacies. The CDC recommends that travelers visiting areas with chikungunya outbreaks in 2025 receive vaccination.
