    BEIJING, Aug.4 (Xinhuanet) -- The first case of West Nile Virus this year in Pennsylvania has been reported by Pennsylvania Health Secretary Dr. Calvin B. Johnson, according to Echo Pilot Thursday.

    The man from York County, Pennsylvania, was hospitalized and released and has recovered.

    "The fact we have seen the first human infection from West Nile reminds all of us that we should take precautions to help reduce the risk of illness," Johnson said.

    "The chance of contracting West Nile Virus from an infected mosquito is small, and your chances of becoming seriously ill are even smaller. However, it is important to keep in mind that all Pennsylvanians - particularly older adults and people with compromised immune systems - should take simple precautions to reduce their risk."

    West Nile Virus is spread to people and animals by infected mosquitoes. The virus can cause West Nile encephalitis, an inflammation of the brain. While anyone can contract the virus, older adults and people with compromised immune systems are at highest risk of developing the disease, he added.

    Officials said flooding in late June has enhanced the possibility of larger mosquito populations.

    People with mild infections of West Nile Virus may experience fever, headache, body aches, skin rash and swollen lymph glands. People with more serious infections may experience high fever, headache, neck stiffness, stupor, disorientation, coma, tremors, occasional convulsions and paralysis.

    There is no specific treatment for West Nile Virus. While most people fully recover, in severe cases, hospitalization is needed. Enditem
