Advances and challenges in eliminating mother-to-child transmission of hepatitis B virus worldwide
-
摘要: 目前,全球89.8%的国家和地区有孕产妇乙型肝炎检测的政策。2022年,全球乙型肝炎疫苗出生接种率、第3剂接种率分别为45%、85%,约3%高病毒载量孕产妇接受了抗病毒治疗,5岁及以下儿童乙型肝炎表面抗原流行率约为0.7%。全球各国乙型肝炎母婴传播取得阶段性进展,但进展差异较大,且面临诸多挑战。全球各地乙型肝炎流行情况、疫苗接种情况、抗病毒药物获取情况不同,此外,实验室检测能力不足、感染孕产妇难以持续获得治疗干预等因素均对消除HBV母婴传播造成了阻碍。

Abstract: At present, there are policies for hepatitis B testing in 89.8% of countries and regions around the world. In 2022, the global hepatitis B vaccine birth dose coverage reached 45%, while the third-dose coverage reached 85%. Approximately 3% of pregnant women with high viral loads have received antiviral therapy, and the prevalence rate of HBsAg is about 0.7% among children aged≤5 years. While significant progress has been made in various countries towards eliminating mother-to-child transmission of hepatitis B virus (HBV), there are still large gaps across countries and numerous challenges. There are differences in the prevalence of hepatitis B, vaccination, and access to antiviral drugs across the globe, and in addition, the factors such as insufficient laboratory testing capacity and difficulties in ensuring sustained access to treatment among pregnant and parturient women with HBV infection pose obstacles to eliminating the mother-to-child transmission of HBV. -
