ST. PETERSBURG, Fla. (970 WFLA) - Pinellas County Health officials say a sentinel chicken kept in Sawgrass Lake Park in St. Petersburg has tested positive for Eastern Equine Encephalitis. The disease can be transmitted to humans through a mosquito bite. Symptoms include headaches, fever, chills and vomitting and can progress quickly. Even though EEE is rare in humans, two cases have been reported in the state this year. The last human case in Pinellas County was reported three years ago. Officials say the best way to prevent EEE is to prevent mosquito bites by wearing long sleeves and pants at dawn and dusk and using mosquito repellent. Also, remove any standing water around your home.
