　　Hepatitis E
　　Hepatitis is a general term meaning inflammation of the liver. Hepatitis is a disease that can be caused by a variety of different viruses such as hepatitis A, B, C, D and E. Since the development of jaundice is a characteristic feature of liver disease, a correct diagnosis can only be made by testing patients' sera for the presence of specific viral antigens and/or anti-viral antibodies.
　　Hepatitis E (HEV) was not recognized as a distinct human disease until 1980. Hepatitis E is caused by infection with the hepatitis E virus, a non-enveloped, positive-sense, single-stranded RNA virus.
　　Although man is considered the natural host for HEV, antibodies to HEV or closely related viruses have been detected in primates and several other animal species.

　　戊肝
　　肝炎是一类肝脏感染的统称。肝炎是一类可以由许多不同病毒，如甲肝、乙肝、丙肝、丁肝和戊肝病毒引起的疾病。由于黄疸的进展是肝脏疾病的一个特征性标志，一个正确的诊断只能通过病人现在的血清病毒学检查和／或抗体检查来判定。
　　戊肝一直不被大家所知，而直到1980年才被人类确定为一个特异性疾病。戊肝是由于戊肝病毒感染引起，它是一种没有包膜的，单转录ＲＮＡ病毒。
　　尽管人被认为是戊肝病毒的天然宿主，戊肝抗体或密切相关的病毒已经在灵长类动物和集中其他物种动物的体内被发现。

　　个人直译，如果有不准，大家可以提出来，核实后马上修改！

　　How is HEV transmitted?
　　HEV is transmitted via the faecal-oral route. Hepatitis E is a waterborne disease, and contaminated water or food supplies have been implicated in major outbreaks. Consumption of faecally contaminated drinking water has given rise to epidemics, and the ingestion of raw or uncooked shellfish has been the source of sporadic cases in endemic areas. There is a possibility of zoonotic spread of the virus, since several non-human primates, pigs, cows, sheep, goats and rodents are susceptible to infection. The risk factors for HEV infection are related poor sanitation in large areas of the world, and HEV shedding in faeces.
　　Person-to-person transmission is uncommon. There is no evidence for sexual transmission or for transmission by transfusion.

　　戊肝如何传播？
　　戊肝是通过粪－口途径进行传播的。戊型肝炎是水性疾病，并且被污染的水或食物都有可能造成戊肝的传播。饮用污染过的水源都会发生感染，而且吞食生吃或生贝壳类动物的零星个案一直在流行地区被发现。还有一种传染途径——人畜共患病毒的蔓延，由于一些非人类的灵长类动物，猪，牛，绵羊，山羊和啮齿动物很容易受到感染。戊肝感染因素和当地相对较差的条件有关，而且部分戊肝病毒直接来源于牲畜的粪便。
　　人对人传染极为罕见。目前并没有证据表面戊肝可以通过性传播或由输血传播。
