婴幼儿乙型肝炎病毒感染及影响因素的研究

A Study on the Infection of Hepatitis B Virus and Its Determinants in Newborns and Infants

摘要: 近年来，国内外对婴幼儿乙型肝炎病毒(HBV)感染的研究极为重视，不少报导认为多数人均已在生命初期受到HBV感染，而且婴幼儿HBsAg阳性血症与母亲HBsAg阳性有密切相关。我们于1981—1983年对HBsAg阳性32名和HBsAg阴性32名的母亲及其所生婴幼儿的HBV感染及影响因素，进行了前瞻性研究。

Abstract: Thirty two newborn and infants whose mothers were positive for HBsAg and another 32 whose mothers were HBsAg-negative had been followed up for 2 years. The HBsAg-positive rates were 65.6% and 3.1% respectively. The rates of HBV infection were 75.0% and 3.1% respectively. Of 21 HBsAg-positive children, 17(80.9%)became chronic arriers.
