What’s going on in Brevard County this year?
This question was brought up in a recent Florida Today article:
Experts are still stumped as to why a disease typically found in the tropics is originating for the fist time from within Brevard's borders.
"We're getting more tropical, in a way," Joseph Faella, director of Brevard County Mosquito Control, said of the warmer, wetter conditions that favor the kinds of mosquitoes that spread dengue. "I do worry ... I guess it was just our turn."
The Florida Department of Health in Brevard County (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.
