对乙型肝炎垂直传播(Vertical transmission)的含义目前尚有不同的看法。一般认为,所谓乙型肝炎垂直传播,即妊娠期患急性或慢性乙型肝炎或慢性无症状乙型肝炎表面抗原(HBsAg)携带者母亲将乙型肝炎病毒(HBV)传播给其婴儿并引起婴儿感染的过程。Stokes等于1951年首先证明病毒性肝炎垂直传播的存在。随着乙型肝炎血清学指标的发现,乙型肝炎的这种传播方式逐渐受到人们的重视。在世界上某些地区乙型肝炎垂直传播率是很高的,它是造成乙型肝炎家庭聚集性的重要原因,是人群中存在的大量HBsAg携带者的重要来源,亦可能与某些地区原发性肝细胞癌的发生有关。因此研究乙型肝炎垂直传播的发生规律并寻找有效的预防办法是十分必要的。本文仅就
There are different opinions on the meaning of vertical transmission of hepatitis B. It is generally accepted that the so-called vertical transmission of hepatitis B, the mother of hepatitis B virus (HBV) carriers of acute or chronic hepatitis B or chronic asymptomatic hepatitis B surface antigen (HBsAg) in pregnancy, spreads to infants and causes infants The process of infection. Stokes equals 1951 that first demonstrated the existence of vertical transmission of viral hepatitis. With the discovery of serological markers of hepatitis B, this mode of transmission of hepatitis B has been paid more and more attention by people. In some parts of the world, the high rate of vertical transmission of hepatitis B is an important reason for the clustering of hepatitis B patients and an important source of large numbers of HBsAg carriers in the population. It may also be related to some regions of the original Occurrence of hepatocellular carcinoma. Therefore, it is necessary to study the law of vertical transmission of hepatitis B and find effective preventive measures. This article just
