Serious Symptoms in a Few People. About one in 150 people infected with WNV will develop severe illness. The severe symptoms can include high fever, headache, neck stiffness, stupor, disorientation, coma, tremors, convulsions, muscle weakness, vision loss, numbness and paralysis. These symptoms may last several weeks, and neurological effects may be permanent.
Milder Symptoms in Some People. Up to 20 percent of the people who become infected have symptoms such as fever, headache, and body aches, nausea, vomiting, and sometimes swollen lymph glands or a skin rash on the chest, stomach and back. Symptoms can last for as short as a few days, though even healthy people have become sick for several weeks.
No Symptoms in Most People. Approximately 80 percent of people (about 4 out of 5) who are infected with WNV will not show any symptoms at all.

Muscle aches
Backache
Lack of appetite
Nausea, vomiting and diarrhea
Skin rash
Swollen lymph glands
In less than 1 percent of infected people, the virus causes a more serious neurological infection, such as inflammation of the brain (encephalitis) or of the brain and surrounding membranes (meningoencephalitis), infection and inflammation of the membranes surrounding the brain and spinal cord (meningitis), and paralysis. Signs and symptoms of these diseases include:

High fever
Severe headache
Stiff neck
Disorientation or confusion
Stupor or coma
Tremors or muscle jerking
Signs and symptoms of Parkinson's disease
Lack of coordination
Convulsions
Partial paralysis
Symptoms of West Nile fever usually last a few days, but symptoms of encephalitis or meningitis can linger for weeks, and certain neurological effects, such as paralysis, may be permanent.
