摘　　要：Objective The current outbreak of Zika virus(ZIKV)poses a severe threat to human health.Two ZIKV strains were isolated from mosquitoes collected from the Dejiang prefecture in China in 2016,which was the first isolation of ZIKV in nature in China.Methods In this study,serum samples were collected from 366 healthy individuals and 104 animals from Dejiang prefecture in 2017,and the plaque reduction neutralization test(PRNT)was used to evaluate the seroprevalence of ZIKV.Results None of the 366 residents from whom the samples were collected were seropositive for ZIKV.None of the 11 pigs from whom the samples were collected were seropositive for ZIKV,while 1 of 63(1.59%)chickens and 2 of 30(6.67%)sheep were seropositive for ZIKV.Conclusions The extremely low seropositivity rate of ZIKV antibodies in animals in the Dejiang prefecture,Guizhou province in this study indicates that ZIKV can infect animals;however,there is a low risk of ZIKV circulating in the local population.Objective The current outbreak of Zika virus(ZIKV) poses a severe threat to human health.
