GAINESVILLE, Fla. (WCJB) – Florida health officials warn of an increase in a mosquito-borne virus known as Eastern Equine Encephalitis (EEE).
Several sentinel chickens tested positive for EEE can spread to humans via infected mosquitoes and cause brain infections and swelling.
According to San Juan County's positive tests for sentinel chickens in Orange County, the risk of transmission to humans has risen.
People develop symptoms about 4 to 10 days after being bitten by an infected mosquito, says the CDC. Signs include sudden headache, high fever, chills and vomiting. Heavier symptoms are disorientation, seizures and coma.
