据估计,丙型肝炎病毒(HCV)无症状携带者约占世界人口的1%。近来血清学研究资料提示 HCV 可从孕妇垂直传播给婴儿。为了验证这一现象,采用聚合酶链反应(PCR)对孕妇及其婴儿进行前瞻性研究,观察母婴垂直传播情况以及婴儿的感染过程。
It is estimated that asymptomatic carriers of hepatitis C virus (HCV) account for about 1% of the world’s population. Recent serological data suggest that HCV can be transmitted vertically to pregnant women from infants. To validate this phenomenon, a prospective study of pregnant women and their infants was conducted by polymerase chain reaction (PCR) to observe the vertical transmission of mother to child and the infection process in infants.
