Zika virus (ZIKV) infection is known as a benign infection usually presenting as an influenza-like illness. However, clusters of microcephaly cases and other neurologic disorders following ZIKV outbreaks in Brazil, as well as a cluster of Guillain-Barré syndrome following an outbreak in French Polynesia in 2014, constitute a Public Health Emergency of International Concern according to WHO. An outbreak of ZIKV infection in New Caledonia occurred in 2014 with 1,380 confirmed cases within a population of 263,000. We report 2 cases of myasthenia gravis (MG) with prior ZIKV infection.
