West Nile Virus (WNV) is a mosquito borne virus that can cause encephalitis (inflammation of the brain) or Meningitis (inflammation of the lining of the brain and spinal cord). The virus first appeared in the United States in 1999 in New York City. It has since made its way westward and now is found in virtually the entire country.

The virus is transmitted through the bites of infected mosquitoes. WNV is not transmitted by person to person contact such as kissing, touching or caring for someone who is infected.

The serious form of the disease is extremely rare. People over 50, young children and those with weakened immune systems are more at risk then others.

Most people who are infected with WNV will not develop any symptoms. A small minority of people may become ill 3 to 15 days after being bitten by an infected mosquito. The symptoms may include fever, headache, body aches, and sometimes skin rash and / or swollen glands.

In rare occasions, WNV infection may result in encephalitis. Encephalitis is an inflammation of the brain that may be marked by headache, high fever, stiff neck, stupor, disorientation, coma, tremors, convulsions, muscle weakness, and paralysis. A small number of cases have been fatal.

Prevention is best done by minimizing exposure to mosquitoes.

1. Eliminate areas of standing, stagnant water
2. Install and maintain screens on windows and doors.
3. Consider minimizing the amount of time you spend outdoors from dusk to dawn.
4. If you are going to be outdoors during peak mosquito times, where protective clothing such as long pants and long sleeve shirts.
5. Spray exposed skin and clothing with repellents containing DEET or permethrin (always read and follow label directions)

Testing of dead birds is unnecessary since West Nile Virus is established in Barry and Eaton Counties.

The virus is only spread through the bite of an infected mosquito. Dead birds can be safely disposed of by placing them in the garbage using a gloved hand or by turning a plastic bag inside out, grasping the bird and then turning the bag back right side out with the bird inside or using a tool such as a shovel.
