1981～1983年,我们对96例 HBsAg阳性母亲和105例HBsAg阴性母亲及其婴儿进行乙肝病毒母婴传播研究,发现HBsAg阳性母亲的婴儿,HBsAg年发生率为43.8％;阴性母亲的婴儿,HBsAg年发生率为1.0％。母亲HBeAg阳性者,其婴儿 HBsAg年发生率83.3％;母亲HBeAe阴性者,其婴儿HBsAg年发生率38.1％。推算母婴传播占当地人群HBsAg携带率的29.6％。
From 1981 to 1983, we studied the mother-to-child transmission of hepatitis B virus in 96 HBsAg-positive mothers and 105 HBsAg-negative mothers and their infants. The incidence of HBsAg in infants born to HBsAg-positive mothers was 43.8% The annual incidence was 1.0%. The mother of HBeAg-positive, the annual incidence of HBsAg in infants 83.3%; mother HBeAe-negative, the incidence of HBsAg in infants 38.1%. Mother-to-child transmission is estimated to account for 29.6% of HBsAg carriers in the local population.
