What are the symptoms of West Nile Virus and who has the greatest risk of becoming severly ill?
Persons who develop symptoms from West Nile Virus may have fever, headache, body aches, swollen lymph glands, tiredness, and may notice a skin rash on the truck of the body.  Symptoms can last just a few days or a person may be ill for several weeks.  Anyone who is experiencing these symptoms is advised to contact their health care provider.  In some individuals, symptoms are severe and they may experience neck stiffness, high fever, headache, muscle weakness, disorientation, tremors, convulsions, paralysis and coma.  People over 50 years of age and those who have weakened immune systems have the greatest risk of becoming severely ill if they are infected with West Nile Virus.
