West Nile fever infection can present with a variety of manifestation according to the severity of the diseases. West Nile fever infection has three different clinical presentations in humans.
- Asymptomatic infection

- Neuroinvasive disease termed West Nile meningitis or encephalitis.[2]
In infected individuals the ratio between the three states is roughly 110:30:1.[3]
