旅行相关军团病是全球范围内的重大公共卫生问题。每年都有大量旅客入住招待所的个案报告,酒店,和水疗中心.的确,热水系统,淋浴,空调系统会被军团菌污染,在25-42°C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暴露在极高的温度下。因此,这项研究是为了评估撒丁岛军团菌对酒店供水系统的定殖,关于最近的欧盟饮用水指令2020/2184,限值为1000CFU/L。方法。共分析112个住宿设施,其中61.3%被军团菌定植,在总共807个样本中,32.5%的军团菌阳性。结果表明,夏季阳性样本数量较多。这也与样品中>1000CFU/L的较高浓度存在相关。因此,这项研究证实,当地酒店经营者应改善其用水安全和预防计划,尤其是在春天和夏天。
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 Legionella, 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 Legionella 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 Legionella, and out of a total of 807 samples, 32.5% were positive for Legionella 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.
