West Nile Virus is transmitted through the bite of a mosquito that has picked up the virus by feeding on a bird infected with the virus. Most people who become infected with West Nile will have either no symptoms or only mild symptoms of illness. Only about two out of ten people who are bitten by an infected mosquito will experience any illness. Illness associated with West Nile is typically mild and includes symptoms such as fever, headache and body aches, but serious illness, such as encephalitis and meningitis are possible. People older than 50 years of age have the highest risk of developing serious illnesses due to West Nile Virus.
