Zika virus (ZIKV) infection has been associated with Guillain-Barré Syndrome (GBS). Roughly 60% of people in countries such as the U.S. live in areas at risk for seasonal spread of ZIKV. ZIKV belongs to a class of diseases that is not typically seen in hospital settings across the U.S. and Europe. We describe the case presentation, management, and treatment of ZIKV infection complicated by GBS. A 64-year-old woman with recent travel to the Dominican Republic presented with rash followed by an acute, ascending polyneuropathy consistent with GBS. She was confirmed to have an acute ZIKV infection by detection of ZIKV nucleic acid by reverse transcription-polymerase chain reaction. She met Brighton Collaboration criteria level 1 evidence for GBS. She received two courses of intravenous immunoglobulin and slowly improved, though still had weakness at discharge. More research is needed to identify the pathophysiology behind ZIKV-associated GBS and its optimal treatment. Prevention is fundamental to limiting infection and spread of ZIKV.
