Signs and symptoms in 32 patients with West Nile virus (WNV)–associated paralysis

Sign/symptom Acute infection,
N = 32, no. (%) 4-mo followup,

N = 22, no. (%)
Fever (temperature >38°C) 29 (91) 0 0

*An apparent increase in the number of persons with tremor, myoclonus, and parkinsonism between 4 mo and 1 y is reflective of detection of these movement disorders in persons who were initially flaccid/immobile, nonambulatory, or too functionally impaired to assess.
