A retrospective cohort study was conducted among persons attending the facility between 30 January and 2 February. Fifty-three of 189 (28%) persons interviewed developed vomiting or diarrhoea within 72\u00a0h after visiting the facility. Five specimens tested positive for norovirus and three specimen sequences were identical. Entering the smaller of the two pools at the facility was significantly associated with illness (RR 5\u00b767, 95% CI 1\u00b75\u201322\u00b70,\n                    <jats:italic>P<\/jats:italic>\n                    =0\u00b7012). The investigation identified several maintenance system failures: chlorine equipment failure, poorly trained operators, inadequate maintenance checks, failure to alert management, and insufficient record keeping. This study demonstrates the vulnerability of recreational water to norovirus contamination, even in the absence of any obvious vomiting or faecal accident. Our findings also suggest that norovirus is not as resistant to chlorine as previously reported in experimental studies. Appropriate regulations and enforcement, with adequate staff training, are necessary to ensure recreational water safety.\n                  <\/jats:p>","DOI":"10.1017\/s0950268806007370","type":"journal-article","created":{"date-parts":[[2006,11,1]],"date-time":"2006-11-01T06:06:38Z","timestamp":1162361198000},"page":"827-833","source":"Crossref","is-referenced-by-count":52,"title":["Outbreak of norovirus illness associated with a swimming pool"],"prefix":"10.1017","volume":"135","author":[{"given":"L.\u00a0J.","family":"PODEWILS","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"L.","family":"ZANARDI BLEVINS","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"HAGENBUCH","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"D.","family":"ITANI","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.","family":"BURNS","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C.","family":"OTTO","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"L.","family":"BLANTON","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S.","family":"ADAMS","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S.\u00a0S.","family":"MONROE","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.\u00a0J.","family":"BEACH","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"WIDDOWSON","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2006,11,1]]},"reference":[{"key":"S0950268806007370_ref007","first-page":"1","article-title":"Surveillance for waterborne-disease outbreaks associated with recreational water\u00a0\u2013\u00a0United States, 2001\u20132002","volume":"53","author":"Yoder","year":"2004","journal-title":"MMWR Surveillance Summary"},{"key":"S0950268806007370_ref004","first-page":"23","article-title":"Surveillance for waterborne-disease outbreaks associated with drinking water\u00a0\u2013\u00a0United States, 2001\u20132002","volume":"53","author":"Blackburn","year":"2004","journal-title":"MMWR Surveillance Summary"},{"key":"S0950268806007370_ref005","doi-asserted-by":"publisher","DOI":"10.1086\/315145"},{"key":"S0950268806007370_ref017","doi-asserted-by":"publisher","DOI":"10.1086\/380132"},{"key":"S0950268806007370_ref006","doi-asserted-by":"publisher","DOI":"10.1017\/S0950268804002249"},{"key":"S0950268806007370_ref002","doi-asserted-by":"publisher","DOI":"10.3201\/eid1101.040426"},{"key":"S0950268806007370_ref001","doi-asserted-by":"publisher","DOI":"10.3201\/eid0505.990502"},{"key":"S0950268806007370_ref013","doi-asserted-by":"publisher","DOI":"10.1093\/oxfordjournals.aje.a113288"},{"key":"S0950268806007370_ref016","doi-asserted-by":"publisher","DOI":"10.1093\/infdis\/171.3.566"},{"key":"S0950268806007370_ref011","doi-asserted-by":"publisher","DOI":"10.1086\/346239"},{"key":"S0950268806007370_ref009","doi-asserted-by":"crossref","first-page":"261","DOI":"10.1128\/AEM.50.2.261-264.1985","article-title":"Inactivation of Norwalk virus in drinking water by chlorine","volume":"50","author":"Keswick","year":"1985","journal-title":"Applied and Environmental Microbiology"},{"key":"S0950268806007370_ref015","doi-asserted-by":"publisher","DOI":"10.1093\/oxfordjournals.aje.a113474"},{"key":"S0950268806007370_ref003","first-page":"841","volume-title":"Fields Virology","author":"Green","year":"2001"},{"key":"S0950268806007370_ref010","unstructured":"10.\u00a0StataCorp.
