本文对发生在某部队家属区的一起肝炎暴发（43例）进行了调查，发现家属区内的供水管网因年久失修发生渗漏而造成上下水交叉污染。采患者血清做甲、乙、丙、丁、戊型肝炎病毒标志物检测，结果：43名患者的抗-HAVIgM，抗-HCV，抗-HDVIgM，抗-HEVIgM全部阴性，HBsAg阳性2例。提示这是一起介水传播的非甲非成型肝炎暴发流行，经采取有效的防治措施后疫情得到控制。
This article investigates an outbreak of hepatitis (43 cases) that occurred in the family area of a unit and found that the water supply network in the family area was causing cross-contamination of the upper and lower water due to leaks that occurred during periods of disrepair. The patients’ serum was used for the detection of hepatitis A, B, C, D, and E hepatitis virus markers. Results: Of the 43 patients, anti-HAVIgM, anti-HCV, anti-HDVIgM, anti-HEVIgM were all negative, and HBsAg was positive in 2. It is suggested that this is an outbreak of pandemic non-A non-forming hepatitis, and the epidemic is controlled after effective prevention measures are taken.
