An outbreak of hepatitis A involving 15 nurses, two premature infants, and the mother of one infant occurred in an intensive care nursery. The infants became infected after receiving blood transfusions from a donor who shortly thereafter experienced symptoms compatible with hepatitis A and was later found to have serologic evidence of acute hepatitis A. Hepatitis was not suspected clinically in the infants but was documented serologically. One of the infants had an ileostomy with liquid intestinal drainage. Her mother and most, if not all, of the nurses acquired hepatitis from this infant. All 15 nurses had contact with this infant, whereas only four nurses had contact with the second infant. The amount of contact nurses had with this infant clearly was related to their risk of infection. Nurses not actually assigned to this infant but who reported some contact had a significantly lower attack rate than those assigned to the infant. Among assigned nurses, those assigned to more than one shift had 4.7 times the risk of acquiring hepatitis than those assigned to one shift only. No specific nursing techniques or personal habits were documented as being significant risk factors in the infected group of nurses.
在一家重症监护新生儿病房发生了一起甲型肝炎暴发事件，涉及15名护士、两名早产儿以及其中一名婴儿的母亲。这些婴儿在接受了一名献血者的输血后被感染，该献血者此后不久出现了与甲型肝炎相符的症状，后来被发现有急性甲型肝炎的血清学证据。临床上未怀疑这些婴儿感染肝炎，但血清学检测证实了感染。其中一名婴儿进行了回肠造口术，有肠液引流。她的母亲以及大部分（如果不是全部的话）护士都从这名婴儿那里感染了肝炎。所有15名护士都接触过这名婴儿，而只有4名护士接触过第二名婴儿。护士与这名婴儿的接触程度显然与他们的感染风险有关。实际上未被分配照顾这名婴儿但报告有过接触的护士，其发病率明显低于被分配照顾该婴儿的护士。在被分配照顾该婴儿的护士中，被分配多个班次的护士感染肝炎的风险是只被分配一个班次护士的4.7倍。在受感染的护士群体中，没有记录到任何特定的护理技术或个人习惯是显著的危险因素。
