Between 2003 and 2007, 21% (n=100/477) of accommodation sites linked to clusters of two or more cases of Legionnaires’ disease that were investigated by the European Surveillance Scheme for Travel-Associated Legionnaires’ Disease (EWGLINET) went on to be associated with at least one further case, despite reporting that satisfactory control measures had been implemented at the time the cluster was first detected. This paper examines these sites (termed reoffenders) in order to determine whether they share any characteristics that may have contributed to the reoffence. All investigations conducted at cluster sites between 2003 and 2007 were included in the analysis, giving a total of 615 investigations conducted at 477 sites. Every country that investigated more than three cluster sites had to deal with at least one reoffence, and one site reoffended five times. The cases involved in the cluster that stayed elsewhere during their incubation periods could be used to help assess the probability of exposure, and therefore the risk, posed by particular cluster sites. A more extensive investigation and control regime may be needed in some instances to better control the risk of Legionnaires’ disease at an accommodation site.
在 2003 年至 2007 年间，欧洲旅行相关军团病监测计划（EWGLINET）调查的与两个或两个以上军团病病例集群相关的住宿场所中，有 21%（n=100/477）尽管报告在首次发现集群时已实施了令人满意的控制措施，但后来仍与至少一起进一步的病例相关。本文研究了这些场所（称为累犯），以确定它们是否存在任何可能导致再次犯罪的特征。在 2003 年至 2007 年间对集群场所进行的所有调查都包括在分析中，总计对 477 个场所进行了 615 次调查。每个调查了三个以上集群场所的国家都必须应对至少一次累犯，而一个场所累犯了五次。在潜伏期期间住在其他地方的集群病例可用于帮助评估特定集群场所造成的暴露风险，因此风险。在某些情况下，可能需要更广泛的调查和控制措施，以更好地控制住宿场所的军团病风险。
