摘要

流行性乙型脑炎病毒(乙脑病毒)是在我国持续传播的重要虫媒病毒,其引起的流行性乙型脑炎(乙脑)是我国重要的公共卫生问题。多年来,虽然乙脑在我国已得到显著控制,但生态变化和疫苗接种等因素作用,使我国乙脑病例的地理分布、发病人群年龄结构等流行病学特征发生改变。乙脑病毒进化迅速,优势基因型从GⅢ 转变为GⅠ,给乙脑的防控工作带来挑战。该文对我国乙脑的流行特征及乙脑病毒的基因型研究进行综述,为乙脑防控提供参考。

Abstract

Japanese encephalitis virus (JEV) is an important arbovirus that continues to spread in China. Japanese encephalitis (JE) caused by JEV is one of the important public health problems in China. Over the years, despite significant control of JE in China, the geographical distribution of JE cases and the age structure of the affected population have changed due to ecological changes and vaccination. Moreover, JEV has evolved rapidly, and the dominant genotype has changed from GⅢ to GⅠ,which brings challenges to the prevention and control of JE. This paper reviewed the epidemic characteristics of JE and the genotypes of JEV in China, providing reference for the prevention and control of JE.
