Fifty-eight people were sickened and 12 died from a Legionnaires’ disease (LD) outbreak in Quincy, IL, in 2015. The initial outbreak investigation identified deficiencies at the Illinois Veteran’s Home (IVHQ), but these did not account for four community-acquired cases that occurred concurrently with no IVHQ exposure. We broaden the investigation to evaluate seven lines of evidence and assess whether municipal drinking water supply deficiencies potentially contributed to a community-wide outbreak. Notably, 3–6 months prior to the outbreak, the primary disinfectant was changed and corrosion control was interrupted, causing a sustained decrease in disinfectant residuals throughout Quincy’s distribution system. We hypothesize this created more favorable conditions for Legionella growth throughout the system and an increase in water lead levels. These municipal system deficiencies were not identified in prior investigations of the outbreak, but their impacts on public health outcomes are consistent with those of the 2014–2016 Flint Water Crisis. However, they occurred in Quincy without any legal violations in the municipal water system or public acknowledgment of community-wide health risks. This study supports the critical need for improved data collection during changes in municipal water treatment. Additional regulatory and communication requirements can better protect public health from both LD and lead.

伊利诺伊州昆西的市政供水系统缺陷是否导致军团病爆发?
2015年,在伊利诺伊州昆西,五十八人因军团病(LD)暴发而致病,其中十二人死亡。最初的暴发调查确定了伊利诺伊州退伍军人之家(IVHQ)的缺陷,但这些并没有说明四个社区-没有同时发生IVHQ暴露的并发病例。我们扩大了调查范围,以评估7条证据,并评估市政饮用水供应不足是否可能导致了社区范围的暴发。值得注意的是,在疫情爆发前的3-6个月,更换了主要的消毒剂并中断了腐蚀控制,导致整个昆西分布系统中消毒剂残留量的持续减少。我们推测这为军团菌创造了更有利的条件整个系统的增长和水铅含量的增加。在先前的暴发调查中并未发现这些市政系统的缺陷,但它们对公共卫生结果的影响与2014-2016年火石水危机的影响相一致。然而,它们发生在昆西,没有任何法律上的违反市政供水系统的行为,也没有公开承认社区范围的健康风险。这项研究支持在市政水处理变化期间改善数据收集的迫切需求。额外的法规和沟通要求可以更好地保护公共健康不受LD和铅的影响。
