定义
以肝脏炎症和纤维化为特征的一组肝病，由感染一种或多种乙型肝炎病毒、丙型肝炎病毒和丁型肝炎病毒6个月以上引起（无论是否感染艾滋病毒）。即使在肝硬化阶段，也常常没有症状。否则，临床特征包括疲劳、肝缘硬化和肝硬化并发症（肌肉萎缩、腹水、脾肿大/门脉高压）。乙型和丙型肝炎病毒的传播是通过血液和体液污染、性传播以及出生时从母亲传给婴儿（垂直传播）。除了检测特异性抗原（HBsAg）和抗体（抗HCV）外，诊断评估还需要检测病毒核酸(HBV DNA, HCV RNA )。
A group of liver diseases characterised by liver inflammation and fibrosis, caused by less than 6 months of infection with one or more of hepatitis B virus, hepatitis C virus and hepatitis D virus, with or without HIV. Even at stage of cirrhosis there are often no symptoms. Otherwise, clinical features include fatigue, hard liver edge and complications of cirrhosis (muscle wasting, ascites, splenomegaly/portal hypertension). Transmission of hepatitis B and C viruses is by blood and body fluid contamination, sexual transmission, and from mother to baby at the time of birth (vertical transmission). In addition to detection of specific antigens (HBsAg) and antibodies (anti-HCV), diagnostic assessment requires assay of viral nucleic acids (HBV DNA, HCV RNA etc).
