Blumberg发现乙型肝炎抗原(HBAg)以后,开创了关于研究病毒性肝炎、肝硬化和原发性肝癌的崭新途径。在乙型肝炎病毒(HBV)感染流行病学中,母-婴传播极受瞩目。小儿遭受感染之后,固可急性发病甚至导致暴发性肝衰竭,但主要的感染形式为经过亚临床型感染成为持续感染状态,多成为终生携带者(表一)。其中部分病例发展为慢性肝炎、肝硬化乃至肝癌;他们并且是社会上HBV感染的主要传染源,造成HBV感染之蔓延无限,流行不止。鉴于妇产科实践与HBV医院内感染和母子感染的流行病
When Blumberg discovered hepatitis B antigen (HBAg), it pioneered a new approach to studying viral hepatitis, cirrhosis and primary liver cancer. In the epidemiology of Hepatitis B virus (HBV) infection, mother-infant transmission is of great interest. Following infection in children, acute onset of acute may even lead to fulminant hepatic failure, but the main form of infection is subclinical infection becoming a persistent infection, and many become lifelong carriers (Table 1). Some of these cases develop chronic hepatitis, cirrhosis and even liver cancer. They are also the main source of HBV infection in the community, causing the spread of HBV infection to an unlimited extent. Given the obstetrics and gynecology practice with HBV hospital infection and mother-child infection epidemic
