RESUMEN
Severe infectious diseases,i.e.antibody-dependent enhancement (ADE) resulted from successive infection with different serotypes of dengue virus.After its introduction into Brazil in 2015,Zika virus has spread rapidly to more than 60 countries and regions by the end of November 2016.Some south-east Asian countries including China have also reported cases of ZIKV infection.In recent studies,it was observed that sera cross-reactivity antibodies or such monoclonal antibodies have been elicited by two domains,ED1 and ED2,of envelope (E) protein on Zika or/and Degue virus,and ADE was easily induced by such antibodies.Dengue fever epidemic often occurred in Chinese coastal provinces each year.Then,it will be followed by Zika virus disease.Therefore,we must pay attention to and propose replying measurement for it.
