Japanese encephalitis (JE) is one of severe viral encephalitis that affects individuals in Asia, western Pacific countries, and northern Australia. Although 67,900 JE cases have been estimated among 24 JE epidemic countries annually, only 10,426 have been reported in 2011. With the establishment of JE surveillance and vaccine use in some countries, the JE incidence rate has decreased; however, serious outbreaks still occur. Understanding JE epidemics and identifying the circulating JE virus genotypes will improve JE prevention and control. This review summarizes the current epidemiology data in these countries.
日本脑炎（JE）是一种严重的病毒性脑炎，影响亚洲、西太平洋国家和澳大利亚北部的人群。尽管估计每年24个日本脑炎流行国家中有67900例日本脑炎病例，但2011年仅报告了10426例。随着一些国家建立日本脑炎监测和疫苗使用，日本脑炎发病率有所下降；然而，严重疫情仍有发生。了解日本脑炎流行情况并确定循环的日本脑炎病毒基因型将改善日本脑炎的预防和控制。本综述总结了这些国家目前的流行病学数据。
