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\u201342 \u00b0C. Studies have shown that in Sardinia, especially during the summer months, the water circulation in the hotels\u2019 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 &gt;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.<\/jats:p>","DOI":"10.3390\/ijerph20186722","type":"journal-article","created":{"date-parts":[[2023,9,7]],"date-time":"2023-09-07T10:09:50Z","timestamp":1694081390000},"page":"6722","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Legionella spp. Monitoring in the Water Supply Systems of Accommodation Facilities in Sardinia, Italy: A Two-Year Retrospective Analysis"],"prefix":"10.3390","volume":"20","author":[{"given":"Luisa","family":"Marras","sequence":"first","affiliation":[{"name":"Department of Medical Sciences and Public Health, University of Cagliari, 09124 Cagliari, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1791-8718","authenticated-orcid":false,"given":"Giacomo","family":"Bertolino","sequence":"additional","affiliation":[{"name":"Pharmaceutical Department, Azienda Ospedaliero, Universitaria di Cagliari, 09123 Cagliari, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adriana","family":"Sanna","sequence":"additional","affiliation":[{"name":"Department of Medical Sciences and Public Health, University of Cagliari, 09124 Cagliari, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Valentina","family":"Carraro","sequence":"additional","affiliation":[{"name":"Department of Medical Sciences and Public Health, University of Cagliari, 09124 Cagliari, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6019-5143","authenticated-orcid":false,"given":"Valentina","family":"Coroneo","sequence":"additional","affiliation":[{"name":"Department of Medical Sciences and Public Health, University of Cagliari, 09124 Cagliari, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,9,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"7","DOI":"10.1016\/j.idc.2016.10.002","article-title":"Microbiology and Epidemiology of Legionnaire\u2019s Disease","volume":"31","author":"Burillo","year":"2017","journal-title":"Infect.
