Pinellas County, Fla. — The Florida Department of Health in Pinellas County (DOH-Pinellas) is informing residents of two confirmed cases of locally-acquired dengue. DOH-Pinellas and Pinellas County Mosquito Control are coordinating surveillance and prevention efforts by conducting treatment, such as increased truck fogging, aerial larviciding, and localized ground inspections for breeding locations.  

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-Pinellas reminds the community to avoid mosquito bites by taking basic precautions. More information is available in English, Spanish and Creole

  • Wear protective clothing to prevent mosquito bites. Wear loose-fitting, long-sleeved shirts and pants. 
  • Apply insect repellents that are registered by the U.S. Environmental Protection Agency  to exposed skin and clothing. When used as directed, EPA-registered insect repellents are proven safe and effective, even for pregnant and breastfeeding women. 
  • Control mosquitoes inside and outside. Repair damaged screening on windows, doors, porches, and patios. Drain water from garbage cans, buckets, pool covers, coolers, toys, flowerpots, or any other containers where sprinkler or rainwater has collected. 

The Department continues to conduct statewide surveillance for mosquito-borne illnesses, including West Nile virus, 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

If you are experiencing any symptoms, please call your healthcare provider.
