Due to an unexpected technical error, patients at a dialysis unit who were seronegative for hepatitis C virus (HCV) were temporarily transferred to another dialysis unit next to a ward reserved for HCV-seropositive patients. In the following 7 months, 17 patients were diagnosed as anti-HCV positive. The aim of the study was to reveal the cause of this nosocomial infection. Anti-HCV-positive sera were further tested by molecular methods. Data collection and on-site epidemiologic inspections were carried out. The source of the nosocomial infection proved to be a seropositive patient treated at the unit, who died before the outbreak was recognized. The exact date of the infection was determined.
由于一个意外的技术错误，一批 HCV 抗体阴性的透析病人被临时转移到紧邻一间预留给 HCV 阳性病人的病房的透析单元，随后的 7 个月内，有 17 名病人被诊断为抗 HCV 阳性。本研究的目的是要找出这次院内感染的原因。进一步用分子生物学方法检测抗 HCV 阳性血清，收集资料并进行现场流行病学调查。感染源被证实是一个在该单元接受治疗的 HCV 阳性病人，在暴发被确认前已经死亡。确切的感染日期被确定。
