About 5% of the children adopted to Sweden from mostly India and Korea are chronic carriers of HBsAg. Most of them are also e-antigen positive. In this investigation 12 families with such children have been studied to evaluate the infectivity risk. Out of 36 family members 5 have had clinical hepatitis, another 2 were HBsAg positive without clinical symptoms and 15 had anti-HBs. It seems clear that these children are a source of infection and all children adopted from countries with high prevalence of hepatitis B should be screened to be able to define the risk group.
从主要印度和韩国收养到瑞典的儿童中，约5%是乙肝表面抗原（HBsAg）的慢性携带者。他们中的大多数也是e抗原阳性。在这项调查中，对12个有此类儿童的家庭进行了研究，以评估感染风险。在36名家庭成员中，5人患过临床型肝炎，另外2人HBsAg阳性但无临床症状，15人有乙肝表面抗体（抗-HBs）。显然，这些儿童是传染源，所有从乙肝高流行国家收养的儿童都应进行筛查，以便确定风险群体。
