Living with West-Nile encephalitis
A form of West Nile virus infection that reaches the brain and nervous system.
Understanding West-Nile encephalitis
West Nile virus is usually spread to people by infected mosquitoes. Encephalitis occurs when the virus crosses the blood-brain barrier and infects the central nervous system. Anyone can be affected, but risk is highest in people over 60, organ transplant recipients, and people with certain conditions such as cancer, diabetes, high blood pressure, and kidney disease.

Symptoms vary from person to person. GARD lists these:
