Advance in Zika virus infection-related myelitis
Zika virus belongs to the family Flaviviridae, genus Flavivirus and is mainly transmitted to humans by Aedes. The outbreak of Zika virus infection in South America in 2015 raised worldwide health concern due to the increasing incidence of microcephaly, Guillain-Barre syndrome and myelitis, although most of the patients were asymptomatic. Here, to further understand and elucidate the pathogenic mechanism of Zika virus infection-associated myelitis, this review summarized the latest advance in biological characteristics, transmission and treatment of Zika virus infection as well as the related case reports and possible mechanisms.
