Fifty-two separate space-time analyses were run, one simulation for each week of 2002. Identified clusters were described in terms of space, time, risk factors reported by involved case-patients, and cases' links to venue-associated outbreaks.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results.<\/jats:title>\n                    <jats:p>Twelve live clusters were detected at the p&lt;0.05 significance level: two single-household clusters and 10 community clusters. The community clusters ranged in size from 194 to 367 census tracts (median = 294), and in disease burden from 21 to 41 cases (median = 29). Geographically, all of the community clusters were located in the west-central part of the city and had a temporal span of 28 days. Within the 10 community clusters, 15 different day care centers were identified as potential exposure settings for case-patients or their close contacts.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions.<\/jats:title>\n                    <jats:p>The prospective space-time scan statistic offers local health departments an objective way of describing clusters of shigellosis cases. The method used in this study could help prioritize the assignment and investigation of cases, particularly when overall shigellosis incidence exceeds expected numbers or when an agency's resources are stressed by other events, such as outbreaks.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/003335490612100206","type":"journal-article","created":{"date-parts":[[2017,7,3]],"date-time":"2017-07-03T22:30:38Z","timestamp":1499121038000},"page":"133-139","source":"Crossref","is-referenced-by-count":37,"title":["Use of a Prospective Space-Time Scan Statistic to Prioritize Shigellosis Case Investigations in an Urban Jurisdiction"],"prefix":"10.1177","volume":"121","author":[{"given":"Roderick C.","family":"Jones","sequence":"first","affiliation":[{"name":"Communicable Disease Program, Chicago Department of Public Health, Chicago, IL"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Monica","family":"Liberatore","sequence":"additional","affiliation":[{"name":"Gordon Technical High School, Chicago, IL [at the time of this research, Ms. Liberatore was with the Immunization Program, Chicago Department of Public Health, Chicago, IL]"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Julio R.","family":"Fernandez","sequence":"additional","affiliation":[{"name":"Communicable Disease Program, Chicago Department of Public Health, Chicago, IL"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Susan I.","family":"Gerber","sequence":"additional","affiliation":[{"name":"Communicable Disease Program, Chicago Department of Public Health, Chicago, IL"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2006,3,1]]},"reference":[{"key":"bibr1-003335490612100206","doi-asserted-by":"publisher","DOI":"10.3201\/eid0505.990502"},{"key":"bibr2-003335490612100206","doi-asserted-by":"publisher","DOI":"10.1086\/386326"},{"key":"bibr3-003335490612100206","doi-asserted-by":"publisher","DOI":"10.2105\/AJPH.85.6.812"},{"issue":"3","key":"bibr4-003335490612100206","first-page":"60","volume":"53","year":"2004","journal-title":"MMWR Morb Mortal Wkly Rep"},{"key":"bibr5-003335490612100206","doi-asserted-by":"publisher","DOI":"10.1001\/archpedi.157.6.601-a"},{"issue":"37","key":"bibr6-003335490612100206","first-page":"797","volume":"50","year":"2001","journal-title":"MMWR Morb Mortal Wkly Rep"},{"key":"bibr7-003335490612100206","doi-asserted-by":"publisher","DOI":"10.1093\/oxfordjournals.aje.a115429"},{"key":"bibr8-003335490612100206","doi-asserted-by":"publisher","DOI":"10.1086\/517825"},{"issue":"42","key":"bibr9-003335490612100206","first-page":"922","volume":"50","year":"2001","journal-title":"MMWR Morb Mortal Wkly Rep"},{"key":"bibr10-003335490612100206","doi-asserted-by":"publisher","DOI":"10.3201\/eid1006.030599"},{"key":"bibr11-003335490612100206","volume-title":"GIS and Public Health","author":"Cromley EK","year":"2002"},{"key":"bibr12-003335490612100206","doi-asserted-by":"publisher","DOI":"10.1016\/0277-9536(95)00183-2"},{"key":"bibr13-003335490612100206","doi-asserted-by":"publisher","DOI":"10.1023\/B:JOMS.0000032851.76239.e3"},{"key":"bibr14-003335490612100206","doi-asserted-by":"publisher","DOI":"10.1086\/314050"},{"key":"bibr15-003335490612100206","doi-asserted-by":"publisher","DOI":"10.1089\/153036604773083004"},{"key":"bibr16-003335490612100206","volume-title":"ArcView: Version 8.2","author":"ESRI, Inc.","year":"2001"},{"key":"bibr17-003335490612100206","volume-title":"Microsoft Corporation, Microsoft Access 2000","year":"1999"},{"key":"bibr18-003335490612100206","volume-title":"SAS: Version 8.2 for Windows","author":"SAS Institute Inc.","year":"2001"},{"key":"bibr19-003335490612100206","volume-title":"Intelligent Dispatcher: Version 1.6","author":"Chicago Department of Business and Information Services","year":"2002"},{"key":"bibr20-003335490612100206","unstructured":"Kulldorf M, Information Management Services, SaTScan: Version 4.0.2, 2003.
