Florida's Space Coast Reports Sixth Local Dengue Case

Historically, local cases of dengue fever have been concentrated in Miami-Dade County. However, recent reports indicate that mosquitoes in northeast Florida are now also transmitting the disease, placing about 600,000 people at risk.

On August 2, 2025, the Brevard County health department reported its sixth locally acquired dengue case of the year.

In response, the Florida Department of Health in Brevard County (DOH-Brevard) has issued a Mosquito-Borne Illness Alert that expires in September 2025.

DOH-Brevard and Brevard County Mosquito Control are coordinating surveillance and prevention efforts along this Atlantic Ocean coastal community by enhanced monitoring for mosquitoes and diseases, as well as targeted mosquito treatment and overnight spraying to reduce the risk of disease transmission.

This area of Florida includes these cities: Melbourne, Titusville, and Cocoa Beach. And to the west, Orlando.

Two other local dengue cases were reported by Miami-Dade in 2025.

Furthermore, there have been over 120 travel-related dengue cases confirmed in Florida in 2025.

Dengue fever is not contagious, causes flu-like symptoms, and can be prevented with vaccination. Currently, a first-generation dengue vaccine is being evaluated in children living in Puerto Rico. 

Globally, a second-generation dengue vaccine is offered in numerious countries in 2025.
