INTRODUCTION: Neuromuscular clinical manifestations during acute West Nile virus (WNV) infection are well documented; however, long-term neurologic outcomes still require investigation.

METHODS: We conducted a long-term follow-up study in patients with history of WNV infection. Of the 117 patients who participated in neurologic and neurocognitive evaluations, 30 were referred for neuromuscular and electrodiagnostic evaluation based on abnormal findings.

RESULTS: We found that 33% of these patients (10 of 30) showed abnormalities on nerve conduction and/or needle electromyography due to primary or secondary outcomes of WNV infection. Most common electrodiagnostic findings and causes of long-term disability were related to anterior horn cell poliomyelitis (WNV poliomyelitis). Electrical data on these patient populations were similar to those observed in chronic poliomyelitis.

DISCUSSION: With more than 16,000 cases of WNV neuroinvasive disease reported across the USA since 1999, understanding clinical outcomes from infection will provide a resource for physicians managing long-term care of these patients. Muscle Nerve 57: 77-82, 2018.
