What are the symptoms of West Nile viral infection?
Most people who are infected with West Nile virus either have no symptoms or experience mild illness such as a fever, headache and body aches before fully recovering. Some persons also develop a mild rash or swollen lymph glands. In some individuals, particularly the elderly, West Nile virus can cause serious disease that affects brain tissue. At its most serious, it can cause permanent neurological damage and can be fatal. Symptoms of encephalitis (inflammation of the brain) include the rapid onset of severe headache, high fever, stiff neck, confusion, loss of consciousness (coma), or muscle weakness, and may be fatal.
