WEST NILE VIRUS

    

What is it? West Nile virus is an infection spread by the bite of an infected mosquito, and can affect people, horses, many types of birds, and some other animals.

 

Where does it occur? As of September 2002, most cases have been clustered in Louisiana, Mississippi and Texas.  The West Nile virus has been identified in humans in both Wisconsin and Minnesota.  There have been five reported human cases  in Wisconsin with one death attributed to the virus.

 

What are the symptoms? Most people who become infected with West Nile virus will either have no symptoms or only minor flu-like symptoms, such as fever, headache and body aches.  On rare occasions, West Nile virus infection can result in a severe and sometimes fatal illness know as West Nile encephalitis (an inflammation of the brain). Symptoms of encephalitis include high fever, severe headache, stiff neck, confusion, loss of consciousness, seizures, muscle weakness and paralysis.  The risk of severe disease is higher for persons 50 years of age or older.

 

What can I do to protect myself? Preventing mosquito bites will prevent West Nile virus infection.   To avoid mosquito bites:

  • Apply insect repellant containing DEET when you are outdoors

  • Consider staying indoors at dawn, dusk and in the early evening

  • Wear long-sleeved clothing and long pants treated with repellants containing permethrin or DEET, since mosquitoes may bite through thin clothing

  • Eliminate the number of places available for mosquitoes to lay their eggs by eliminating standing water from around your home or apartment
