定义
感染乙型肝炎病毒6个月以上引起的肝脏炎症和纤维化为特征的肝病。即使到了肝硬化阶段，往往也没有任何症状。否则，临床特征包括疲劳、肝缘硬化和肝硬化的并发症（肌肉萎缩、腹水、脾肿大/门脉高压）。传播途径为血液和体液污染、性传播和出生时母婴传播（垂直传播）。通过检测HBsAg来确诊，但评估严重程度、预后和治疗指征需要定量血清中HBV DNA。
A liver disease characterised by liver inflammation and fibrosis caused by more than 6 months of infection with the hepatitis B virus. 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 is by blood and body fluid contamination, sexual transmission, and from mother to baby at the time of birth (vertical transmission). Confirmation of the diagnosis is by detection of HBsAg, but assessment of severity, prognosis and indication for treatment requires quantification of HBV DNA in serum.
