Abstract

An outbreak of hepatitis type A occurred among military personnel and dependents on a military post in Anchorage, Alaska, August 1976-April 1977. One hundred sixteen clinical cases of hepatitis were identified over a nine-month-period. Ninety-six per cent of those cases that were tested demonstrated IgM antibody to hepatitis A virus. A large child care facility was implicated as a major focus of hepatitis virus transmission. Sixty-four (55%) of the cases were directly or indirectly linked to the child care facility. The length of time that a child spent at the facility appeared to increase the child's risk of developing hepatitis and the risk of his transmitting the hepatitis A virus to other members of the immediate household.

摘要

1976年8月至1977年4月期间，阿拉斯加安克雷奇的一个军事基地内，军人及其家属中爆发了甲型肝炎疫情。在九个月的时间里，共确诊了116例临床肝炎病例。在接受检测的病例中，96%显示出抗甲型肝炎病毒的IgM抗体。一家大型儿童保育机构被认为是肝炎病毒传播的主要源头。其中64例（55%）病例直接或间接与该儿童保育机构有关。儿童在该机构停留的时间越长，其感染肝炎的风险以及将甲型肝炎病毒传播给直系家庭成员的风险似乎就越高。
