In May 2023, the Shelby County Health Department identified a legionellosis outbreak among attendees of the same church. Epidemiologic, environmental, and laboratory investigations were initiated. Laboratory-based surveillance identified persons with a positive test result. Church attendees were surveyed about attendance, symptoms of legionellosis, and water exposures. Environmental assessment of the church included asking about recent water management practices and collecting samples from water sources for culture. The health department identified 16 church attendees who had legionellosis symptoms. Of these, 9 (56%) had positive laboratory test results for , 7 were hospitalized, and none died. Our investigation revealed that recent changes in water management practices at the church included renewed operation of a large, jetted baptismal font. In all, 17 environmental samples were collected; of these samples, 5 (including 4 from the baptismal font) had serogroup 1 isolated by culture. Environmental sampling was crucial in identifying the baptismal font as the likely source of . Education about water management and remediation recommendations were provided to staff at the church.
2023年5月，谢尔比县卫生部门在同一教堂的与会者中发现了军团病疫情。随即展开了流行病学、环境和实验室调查。基于实验室的监测确定了检测结果呈阳性的人员。对教堂与会者进行了关于出席情况、军团病症状以及水暴露情况的调查。对教堂的环境评估包括询问近期的水管理做法，并从水源采集样本进行培养。卫生部门确定了16名有军团病症状的教堂与会者。其中，9人（56%）实验室检测结果呈阳性，7人住院，无人死亡。我们的调查显示，该教堂近期水管理做法的变化包括重新启用一个大型的、有喷头的洗礼池。总共采集了17份环境样本；在这些样本中，有5份（包括4份来自洗礼池的样本）通过培养分离出嗜肺军团菌血清1型。环境采样对于确定洗礼池为可能的嗜肺军团菌来源至关重要。已向教堂工作人员提供了有关水管理和整治建议的教育。
