Viral hepatitis are essentially caused by 5 types of viruses which differ in way of transmission and their evolution to chronicity or not. Like the virus causing hepatitis A, the E-virus-discovered en 1983-is a virus with oral-fecal transmission, responsible only for acute hepatitis which may be fulminant, notably in pregnant woman. Responsible for epidemics in Asia and Africa, the E-virus is nearly non-existent in our regions. Just like the B, C and D viruses, the G-virus is a RNA-virus with intravenous transmission. Notwithstanding a high prevalence, its pathogenic role remains hypothetical so that some hesitate to consider it as a virus causing clinical hepatitis. Etiological viral or non-viral agents for the cryptogenic hepatitis which can appear as acute, fulminant, post-transfusional or chronic illness, remain to be discovered.
病毒性肝炎主要由5种病毒引起，它们在传播方式以及是否演变为慢性肝炎方面存在差异。例如，导致甲型肝炎的病毒，1983年发现的戊型肝炎病毒，是一种经粪口传播的病毒，仅引起急性肝炎，可能是暴发性的，尤其是在孕妇中。戊型肝炎病毒在亚洲和非洲引发疫情，在我们所在地区几乎不存在。与乙型、丙型和丁型病毒一样，庚型肝炎病毒是一种经静脉传播的RNA病毒。尽管其感染率很高，但其致病作用仍属假设，因此一些人对是否将其视为导致临床肝炎的病毒犹豫不决。隐源性肝炎的病因，无论是病毒性还是非病毒性因素，都可能表现为急性、暴发性、输血后或慢性疾病，仍有待发现。
