Travel-associated Legionnaires' disease is a significant public health concern worldwide. A high number of cases are reported every year among travellers who stay at guest houses, hotels, and spas. Indeed, hot water systems, showers, and air-conditioning systems can be contaminated by , which grows at 25-42 °C. Studies have shown that in Sardinia, especially during the summer months, the water circulation in the hotels' pipes is exposed to extremely high temperatures. As a result, this study was conducted to assess the colonization of hotel water systems by in Sardinia, concerning a recent EU directive 2020/2184 for drinking water with a limit of 1000 CFU /L. Methods. A total of 112 accommodation facilities were analyzed, of which 61.3% were found to be colonized with , and out of a total of 807 samples, 32.5% were positive for presence. The results showed a higher number of positive samples in the summer season. This was also associated with the higher concentration presence of >1000 CFU/L in the samples. Consequently, this study confirms that local hotel operators should improve their water safety and prevention plans, especially in spring and summer.
旅行相关军团病是全球重大的公共卫生问题。每年在入住宾馆、酒店和温泉浴场的旅行者中报告有大量病例。事实上，热水系统、淋浴器和空调系统可能会被嗜肺军团菌污染，该菌在25至42摄氏度的环境中生长。研究表明，在撒丁岛，尤其是在夏季，酒店管道中的水循环会暴露在极高的温度下。因此，本研究旨在根据欧盟最近关于饮用水的第2020/2184号指令（限值为1000 CFU/L），评估撒丁岛酒店水系统中嗜肺军团菌的定植情况。方法。共分析了112个住宿设施，其中61.3%被发现有嗜肺军团菌定植，在总共807个样本中，32.5%的样本嗜肺军团菌检测呈阳性。结果显示夏季阳性样本数量更多。这也与样本中浓度高于1000 CFU/L的情况更为普遍有关。因此，本研究证实当地酒店经营者应改进其水安全和预防计划，尤其是在春季和夏季。
