用ＥＬＩＳＡ 法对１１０ 名健康孕产妇进行血清抗－ ＨＧＶ 测定， 阳性和可疑阳性者再用ＲＴ－ＰＣＲ 检测血清ＨＧＶ ＲＮＡ，并对ＨＧＶ ＲＮＡ 阳性孕产妇的新生儿脐血和婴儿血进行ＨＧＶ ＲＮＡ 检测。结果１１０ 名孕产妇中有７ 人（６ ．３６％ ） 抗－ ＨＧＶ 阳性，８ 人可疑阳性。其中４ 人被检测到ＨＧＶ ＲＮＡ，阳性率２６ ．６６ ％ （４／１５） 。她们所产的４ 名婴儿中２ 人血清ＨＧＶ ＲＮＡ 阳性，提示ＨＧＶ 的母婴传播率为５０％ （２／４） ，剖宫产可能具有减轻ＨＧＶ 母婴传播的作用。
HGV RNA was detected by reverse transcription-polymerase chain reaction (RT-PCR) in 110 healthy pregnant women with positive and suspicious positives by ELISA, and HGV RNA was detected in neonates with HGV RNA positive pregnant women . Results Of the 110 pregnant women, 7 (6.36%) were positive for anti-HGV and 8 were positive for suspicion. Four of them were detected HGV RNA, the positive rate of 26. 66% (4/15). Serum HGV RNA was positive in 2 out of 4 babies they produced, suggesting a 50% (2/4) maternal-to-infant transmission rate of HGV. Caesarean section may have the effect of reducing mother-infant HGV transmission.
