Infection with WNV can be asymptomtic (no symptoms), or can lead to West Nile fever or severe West Nile disease.
It is estimated that about 20% of people who become infected with WNV will develop West Nile fever. Symptoms include fever, headache, tiredness, and body aches, occasionally with a skin rash (on the trunk of the body) and swollen lymph glands. While the illness can be as short as a few days, even healthy people have reported being sick for several weeks.
The symptoms of severe disease (also called neuroinvasive disease, such as West Nile encephalitis or meningitis or West Nile poliomyelitis) include headache, high fever, neck stiffness, stupor, disorientation, coma, tremors, convulsions, muscle weakness, and paralysis. It is estimated that approximately 1 in 150 persons infected with the West Nile virus will develop a more severe form of disease. Serious illness can occur in people of any age, however people over age 50 and some immunocompromised persons (for example, transplant patients) are at the highest risk for getting severely ill when infected with WNV.
Most people (about 4 out of 5) who are infected with West Nile virus will not develop any type of illness (an asymptomatic infection), however you cannot know ahead of time if you'll get sick or not when infected.

Symptoms of West Nile virus really depend on the person who becomes infected. Kids with normal immune systems (say: im-yune), the system of the body that fights off disease and infection, usually get just a mild "flu-like" illness, and may not feel bad at all with the infection.
People over 50 years old and those with weakened immune systems due to HIV/AIDS, cancer, or organ transplants are most at risk for the infection. Most of the time, symptoms of West Nile virus are similar to the flu and include:
* fever
* headache
* neck and back stiffness
* muscle ache
* tiredness
* joint pain
* swollen glands
* rash
