This case-control study was a secondary analysis of home address data from patients who underwent LUAT at a single eastern Wisconsin health system from 2013 to 2017. Only zip codes within the health system\u2019s catchment area that registered \u2265 3 positive cases and \u2265 50 completed tests, as well as geographically adjacent zip codes with \u2265 2 positive cases and \u2265 50 tests, were included. A 1:3 ratio of cases to randomly selected controls was used. Home addresses were geocoded and mapped using ArcGIS software (Esri); nearest waterway and distance to home was identified. Distance to nearest waterway according to ArcGIS was verified\/corrected using Google Maps incognito. Distances were analyzed using chi-squared and 2-sample t-tests. Overall, mean distance to nearest waterway did not differ between cases (2958 \u00b1 2049 ft) and controls (2856 \u00b1 2018 ft; P = 0.701). However, in a subset of nonurban zip codes, cases were closer to nearest waterway than controls (1165 \u00b1 905 ft vs 2113 \u00b1 1710 ft; P = 0.019). No association was found between cases and type of waterway. Further research is needed to investigate associations and differences between natural and built environmental water sources in relation to legionellosis.<\/jats:p>","DOI":"10.17294\/2330-0698.1872","type":"journal-article","created":{"date-parts":[[2022,4,19]],"date-time":"2022-04-19T04:32:26Z","timestamp":1650342746000},"page":"128-131","source":"Crossref","is-referenced-by-count":3,"title":["Association of Natural Waterways and &lt;i&gt;Legionella pneumophila&lt;\/i&gt; Infection in Eastern Wisconsin: A Case-Control Study"],"prefix":"10.17294","volume":"9","author":[{"given":"Hannah M","family":"William","sequence":"first","affiliation":[{"name":"Advocate Aurora Health; Center for Urban Population Health; University of Wisconsin School of Medicine and Public Health"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kayla","family":"Heslin","sequence":"additional","affiliation":[{"name":"Advocate Aurora Health; Center for Urban Population Health"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jessica J.
