An international team of researchers recently provided evidence linking Zika virus infection to cases of Guillain-Barré syndrome (GBS); (Cao-Lormeau V-M et al. Lancet. doi:10.1016/S0140-6736(16)00562-6 [published online February 29, 2016]).
In a case-control study, investigators analyzed blood samples from 42 patients diagnosed with GBS during the Zika outbreak that occurred in French Polynesia between October 2013 and April 2014. During that period, an increase in the rare autoimmune condition that attacks the peripheral nervous system was reported, raising the possibility of an association between the Zika virus and GBS.
