In a study published in the October 2016
The JNS paper presents the case of a 62-year-old Honduran male patient who traveled to Venezuela and developed acute sensory polyneuropathy during the active phase of infection with Zika virus. The nerve-related symptoms have largely remitted, but improvement took several months.
The case report is part of a collaborative effort involving the World Federation of Neurology Work Group on Zika, a recently established forum convened to contribute expertise to the coordinated global response to the ongoing Zika outbreaks worldwide.
The authors of the case report did not respond to requests for comment from Contagion. However, in a press release issued at the time of its publication, study co-author Marco T. Medina, Dean of the Faculty of Medical Sciences at the Universidad Nacional Autonoma de Honduras, said, “Clinicians should be aware that Zika virus infection can also cause an acute infectious sensory polyneuropathy. Our patient is the first confirmed Zika infection case report associated with an acute sensory polyneuropathy which began during the acute infectious phase. This suggests a probable direct viral inflammatory process affecting sensory nerves, but an autoimmune etiology cannot be definitely excluded."
Of course, as this only the first case report linking the virus with this neurological complication, further study is needed before the association can be confirmed.
