West Nile virus (WNV) serologic evidence has been well demonstrated throughout Turkey. A 43-year-old male patient who presented to emergency service with high fever, rash, muscle weakness, altered mental status and was diagnosed as WNV encephalitis is reported. The patient survived after supportive treatment. This case shows that WNV encephalitis should be considered in the differential diagnosis of patients with aseptic meningitis or encephalitis of unknown etiology especially in summer and early fall in Turkey.
