戊型肝炎食源性传播的研究进展

Advances in foodborne transmission of Hepatitis E

戊型肝炎病毒（HEV）是常见的通过粪-口途径传播的肝炎病毒，猪和鹿等动物是其主要的宿主。人食用这些动物的肉及肉制品就有感染HEV的风险，易引起急性或亚急性戊型肝炎。近年来食源性戊型肝炎流行情况严重，已经成为全球关注的公共卫生问题。此文对HEV病原学、戊型肝炎流行病学特征以及食源性传播情况进行综述，进一步了解HEV食源性传播风险，为预防和控制戊型肝炎的流行提供科学依据。

Hepatitis E virus （HEV） is a common hepacivirus spreading via the fecal-oral route, with the host of swine and other animals. Men who eat the meat and related products made from the infected animals are exposed to the risk of HEV infection, resulting in having acute and sub-acute hepatitis E. In recent years, the prevalence of foodborne hepatitis E is in a serious condition, and has become a critical public health issue. In this article, the etiology of HEV, epidemiological characteristics of hepatitis E and foodborne transmission are reviewed to further understand the HEV foodborne transmission outbreaks, pollution and risks, so as to provide scientific basis for hepatitis E prevention and control.
