Deadly mosquito virus detected in Florida
Florida health officials are warning of an uptick in a mosquito-borne virus known as Eastern equine encephalitis (EEE).
Several sentinel chickens tested positive for EEE, which can spread to humans via infected mosquitoes and cause brain infection and swelling.
Following the positive tests for the sentinel chickens in Orange County, the health department said, "the risk of transmission to humans has increased."
People develop symptoms about 4 to 10 days after they are bitten by an infected mosquito, the CDC says. Signs include sudden onset of headache, high fever, chills and vomiting. More severe symptoms include disorientation, seizures and coma.
