Severe cases include those with meningitis and encephalitis. In these cases, the virus has affected the brain and the tissues that surround the brain. There is also a polio-like syndrome associated with severe infection. 

Most people with West Nile virus do very well and recover completely. For those with a severe infection the outlook depends on their age and the other medical conditions they have which can impact the body's ability to handle this infection.

At this time there is no cure, medication or treatment for West Nile other than managing symptoms and supporting the patient's body as it handles the disease.
