Universal childhood hepatitis B vaccination was introduced in Indonesia in 1997; by 2008, coverage was estimated to be 78%. This study aimed to investigate the serologic status and virologic characteristics of hepatitis B virus (HBV) among the children in East Java. A total of 229 healthy children born during 1994-1999 were enrolled in this study. Overall, 3.1% were positive for hepatitis B surface antigen (HBsAg) and 23.6% were positive for antibody to HBsAg (anti-HBs). HBV DNA was detected in 5 of 222 HBsAg-negative carriers, which were suggested to be cases of occult HBV infection. A single amino substitution (T126I) in the S region was frequently found. HBV infection remains endemic, and the prevalence of anti-HBs remains insufficient among children in East Java, Indonesia.
1997 年印度尼西亚开始在全国范围内为儿童普遍接种乙肝疫苗;到 2008 年,覆盖率估计达到 78%。本研究旨在调查东爪哇儿童中乙型肝炎病毒(HBV)的血清学状况和病毒学特征。本研究共纳入了 229 名 1994-1999 年期间出生的健康儿童。总体而言,3.1%的儿童 HBsAg 阳性,23.6%的儿童抗-HBs 阳性。在 222 名 HBsAg 阴性携带者中,有 5 名检测到 HBV DNA,提示存在隐匿性 HBV 感染。在 S 区经常发现单个氨基酸取代(T126I)。HBV 感染仍然流行,印度尼西亚东爪哇的儿童中抗-HBs 的流行率仍然不足。
