Two hundred and eighty-five healthy Danish children aged between 7 and 17 years were studied for hepatitis B antigen and antibodies to hepatitis A and B. A positive response to each of these infections was found in 0.7% of them. During a 5-year period 40 children were admitted to hospital with viral hepatitis, 30 of whom had hepatitis A. Eighty-three per cent of these cases of hepatitis A were secondary to adult cases, or had resulted from foreign travel. Hepatitis A is no longer endemic in Danish children, and morbidity from hepatitis B or non-A non-B is negligible.
对285名年龄在7至17岁之间的丹麦健康儿童进行了乙型肝炎抗原以及甲型和乙型肝炎抗体的研究。发现其中0.7%的儿童对这些感染中的每一种都有阳性反应。在5年期间,有40名儿童因病毒性肝炎住院,其中30名患有甲型肝炎。这些甲型肝炎病例中有83%继发于成人病例或因出国旅行所致。甲型肝炎在丹麦儿童中已不再是地方性疾病,乙型肝炎或非甲非乙型肝炎的发病率可忽略不计。
