Except from the most obvious sites (cooling towers and hot water systems), infections can also be associated with recreational, water feature, and garden areas of hotels. This argument is of great interest to better comprehend the colonization and to calculate the risk to human health of these sites. From July 2000\u2013November 2017, the public health authorities of the Island of Crete (Greece) inspected 119 hotels associated with TALD, as reported through the European Legionnaires\u2019 Disease Surveillance Network. Five hundred and eighteen samples were collected from decorative fountain ponds, showers near pools and spas, swimming pools, spa pools, garden sprinklers, drip irrigation systems (reclaimed water) and soil. Of those, 67 (12.93%), originating from 43 (35.83%) hotels, tested positive for Legionella (Legionella pneumophila serogroups 1, 2, 3, 6, 7, 8, 13, 14, 15 and non-pneumophila species (L. anisa, L. erythra, L. taurinensis, L. birminghamensis, L. rubrilucens). A Relative Risk (R.R.) &gt; 1 (p &lt; 0.0001) was calculated for chlorine concentrations of less than 0.2 mg\/L (R.R.: 54.78), star classification (&lt;4) (R.R.: 4.75) and absence of Water Safety Plan implementation (R.R.: 3.96). High risk (\u2265104 CFU\/L) was estimated for pool showers (16.42%), garden sprinklers (7.46%) and pool water (5.97%).<\/jats:p>","DOI":"10.3390\/ijerph15040598","type":"journal-article","created":{"date-parts":[[2018,3,26]],"date-time":"2018-03-26T12:08:25Z","timestamp":1522066105000},"page":"598","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":35,"title":["Legionella spp. Risk Assessment in Recreational and Garden Areas of Hotels"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8891-2084","authenticated-orcid":false,"given":"Antonios","family":"Papadakis","sequence":"first","affiliation":[{"name":"Department of Clinical Microbiology and Microbial Pathogenesis, School of Medicine, University of Crete, Voutes\u2014Staurakia, 71110 Heraklion, Crete, Greece"},{"name":"Public Health Authority of Heraklion, 71201 Heraklion, Crete, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dimosthenis","family":"Chochlakis","sequence":"additional","affiliation":[{"name":"Department of Clinical Microbiology and Microbial Pathogenesis, School of Medicine, University of Crete, Voutes\u2014Staurakia, 71110 Heraklion, Crete, Greece"},{"name":"Regional Laboratory of Public Health, School of Medicine, 71110 Heraklion, Crete, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vassilios","family":"Sandalakis","sequence":"additional","affiliation":[{"name":"Department of Clinical Microbiology and Microbial Pathogenesis, School of Medicine, University of Crete, Voutes\u2014Staurakia, 71110 Heraklion, Crete, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria","family":"Keramarou","sequence":"additional","affiliation":[{"name":"Department of Clinical Microbiology and Microbial Pathogenesis, School of Medicine, University of Crete, Voutes\u2014Staurakia, 71110 Heraklion, Crete, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yannis","family":"Tselentis","sequence":"additional","affiliation":[{"name":"Department of Clinical Microbiology and Microbial Pathogenesis, School of Medicine, University of Crete, Voutes\u2014Staurakia, 71110 Heraklion, Crete, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anna","family":"Psaroulaki","sequence":"additional","affiliation":[{"name":"Department of Clinical Microbiology and Microbial Pathogenesis, School of Medicine, University of Crete, Voutes\u2014Staurakia, 71110 Heraklion, Crete, Greece"},{"name":"Regional Laboratory of Public Health, School of Medicine, 71110 Heraklion, Crete, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2018,3,26]]},"reference":[{"key":"ref_1","unstructured":"(2017, December 06).
