During the period October-November 2017, an outbreak of Legionnaires' disease involving 27 cases occurred in the tourist area of Palmanova (Mallorca, Spain). The majority of cases were reported by the European Centre of Disease Prevention and Control (ECDC) as travel associated cases of Legionnaires' disease (TALD). Most cases belonged to different hotel cluster alerts. No cases were reported among the local population residing in the area. All tourist establishments associated with one or more TALD cases were inspected and sampled by public health inspectors. All relevant sources of aerosol emission detected were investigated and sampled. The absence of active cooling towers in the affected area was verified, by documents and on-site. Samples from hot tubs for private use located on the terraces of the penthouse rooms of a hotel in the area were included in the study. Extremely high concentrations (> 10 CFU/l) of , including the outbreak strain, were found in the hot tubs of vacant rooms of this hotel thus identifying the probable source of infection. Meteorological situation may have contributed to the geographical distribution pattern of this outbreak. In conclusion, hot tubs for private use located outdoors should be considered when investigating community outbreaks of Legionnaires' disease of unclear origin.
2017年10月至11月期间，西班牙马略卡岛帕尔马诺瓦旅游区爆发了军团病疫情，涉及27例病例。欧洲疾病预防控制中心（ECDC）报告的大多数病例为与旅行相关的军团病病例（TALD）。大多数病例属于不同的酒店聚集性警报。该地区的当地居民中未报告病例。与一例或多例TALD病例相关的所有旅游设施均由公共卫生检查员进行了检查和采样。对检测到的所有相关气溶胶排放源进行了调查和采样。通过文件和现场核实，确认受影响地区没有运行中的冷却塔。该地区一家酒店顶层房间露台上的私人热水浴缸样本被纳入研究。在该酒店空房的热水浴缸中发现了极高浓度（>10 CFU/l）的 ，包括暴发菌株，从而确定了可能的感染源。气象情况可能对此次疫情的地理分布模式产生了影响。总之，在调查不明来源的社区军团病疫情时，应考虑室外私人热水浴缸。
