关于这个话题,已经知道了什么?乙型肝炎(乙肝)病毒表面抗原[Hepatitis B Virus(HBV)Surface Antigen,HBsAg]阳性产妇分娩的婴幼儿感染HBV的概率是40%~90%,感染HBV的婴幼儿发展为慢性HBV感染的危险为90%,因肝衰竭或肝细胞癌造成早逝。婴幼儿期进行暴露后预防,可预防85%~95%的围生期HBV感染。判断婴幼儿的阻断效果,包括是否需要再免疫,推荐婴幼儿完成HepB全程接种后1个月(9~18月龄)进行免疫后血清学检测(Post Vaccination Serologic Testing,PVST)。这项报告增加了什么?加强HBV母婴传播个案管理项目(Enhanced Perinatal Hepatitis B Case Management Projects,EPHBP)数据显示,报告
What is already known about this topic? The probability of HBV infection in infants infected with HBsAg positive HBsAg positive mothers is 40% -90% of those infected with HBV Infants and young children develop the risk of chronic HBV infection is 90%, due to liver failure or hepatocellular carcinoma caused by premature death. Prenatal and postnatal prophylaxis can prevent 85% to 95% of perinatal HBV infection. To determine the blocking effect of infants and young children, including the need for re-immunization, post-immunization post-immunization serological tests (PVST) should be recommended at 1 month (9-18 months) after completion of HepB inoculation. What is added to this report? Data from the Enhanced Perinatal Hepatitis B Case Management Projects (EPHBP) show that the report
