BROOKSVILLE, Fla. (AP) - Hernando County residents are warned to avoid being bitten by mosquitoes after two chickens tested positive for the West Nile virus.

Mosquito Control Supervisor Guangye Hu says the results mean mosquitoes carrying the virus are present in the area, and residents should be on alert for symptoms that include fever, headache, fatigue, weakness and dizziness.

Hu says they will increase inspection and spraying in the area where the sentinel chickens were located.
