DOH-Brevard Issues Mosquito-Borne Illness Alert

Published on July 30, 2025

The Florida Department of Health in Brevard County (DOH-Brevard) is informing residents of four confirmed cases of locally-acquired dengue. DOH-Brevard and Brevard County Mosquito Control are coordinating surveillance and prevention efforts by enhanced monitoring for mosquitoes and diseases as well as targeted mosquito treatment and overnight spraying to reduce the risk of disease transmission.

Dengue can present as a flu-like illness with severe muscle aches and joint pain, fever, and sometimes a rash. Usually, there are no respiratory symptoms. Symptoms of dengue will appear within 15 days after being bitten by an infected mosquito. Dengue fever is not contagious but is transmitted by the bite of an infected Aedes aegypti mosquito.

DOH-Brevard reminds the community to avoid being bitten by mosquitoes by taking these basic precautions.

The Department continues to conduct statewide surveillance for mosquito-borne illnesses, including West Nile virus infections, Eastern equine encephalitis, St. Louis encephalitis, malaria, chikungunya, and dengue. Residents of Florida are encouraged to report dead birds to the Florida Fish and Wildlife Conservation Commission’s site.

For more information, visit the Department’s website or view the weekly mosquito-borne illness surveillance reports. If you are experiencing any symptoms, please call DOH-Brevard at 321-454-7101.
