Florida's Dengue Cases May Continue Increasing in 2025

In the Region of the Americas, 2024 has been marked as the worst year ever for dengue virus infections, 12.8 million, and related fatalities, 7,855.

From a country perspective, the United States has experienced a significant impact, with dengue cases increasing by approximately 43%. According to the U.S. CDC, 8,863 dengue cases were reported as of mid-December 2024, compared to 6,164 cases in 2023.

Within the U.S., the Florida Department of Health recently reported some unsettling news.

As of late December 2024, 911 travel-associated dengue cases had been reported, mainly by visitors to Brazil (61), Cuba (506), and Puerto Rico (41). Additionally, 85 locally acquired dengue cases were reported from ten counties, led by Miami-Dade (47).

In 2023, 609 travel-associated dengue cases were reported, and 186 humans contracted dengue while in Florida.

With international travel expected to increase in 2025, this CDC data suggests that more international visitors may unintentionally introduce one of the four dengue viruses in Florida next year.

Furthermore, since mosquitoes transmit dengue, locally acquired infections will likely increase next year.

From a disease prevention perspective, there is hope that access to dengue vaccines may improve in 2025 as approved vaccines increase production and vaccine candidates seek approvals.
