In a well-defined geographic area within Kampala, Uganda, residential locations were determined for 85 people diagnosed with TB at local health facilities over an 18-month period and for 60 individuals diagnosed with TB during a subsequent community-wide door-to-door screening campaign. Ten of the individuals diagnosed through community screening lived within 50\u00a0m of an individual previously diagnosed with TB in a local health facility (TB prevalence: 0.98%), and 15 lived at a distance of 50\u2013100\u00a0m (prevalence: 0.87%). The prevalence ratio was 1.4 (95% confidence interval (CI): 0.7\u20132.9) for those &lt;50\u00a0m and 1.2 (95% CI 0.6\u20132.2) for those 50\u2013100\u00a0m, compared to &gt;100\u00a0m. Using TB notifications to identify areas for geographically targeted case finding is at most moderately more efficient than screening the general population in the context of urban Uganda.<\/jats:p>","DOI":"10.1017\/s0950268825100605","type":"journal-article","created":{"date-parts":[[2025,9,26]],"date-time":"2025-09-26T05:37:38Z","timestamp":1758865058000},"update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":0,"title":["The potential yield of geographically targeted tuberculosis contact investigation in urban Uganda"],"prefix":"10.1017","volume":"153","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7789-5779","authenticated-orcid":false,"given":"Katherine O.","family":"Robsky","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/00hjz7x27","id-type":"ROR","asserted-by":"publisher"}],"name":"Georgetown University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Annet","family":"Nalutaaya","sequence":"additional","affiliation":[{"name":"Uganda Tuberculosis Implementation Research Consortium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter James","family":"Kitonsa","sequence":"additional","affiliation":[{"name":"Uganda Tuberculosis Implementation Research Consortium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James","family":"Mukiibi","sequence":"additional","affiliation":[{"name":"Uganda Tuberculosis Implementation Research Consortium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David","family":"Isooba","sequence":"additional","affiliation":[{"name":"Uganda Tuberculosis Implementation Research Consortium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Olga","family":"Nakasolya","sequence":"additional","affiliation":[{"name":"Uganda Tuberculosis Implementation Research Consortium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Emily A.","family":"Kendall","sequence":"additional","affiliation":[{"name":"Uganda Tuberculosis Implementation Research Consortium"},{"id":[{"id":"https:\/\/ror.org\/037zgn354","id-type":"ROR","asserted-by":"publisher"}],"name":"Johns Hopkins University School of Medicine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jonathan","family":"Zelner","sequence":"additional","affiliation":[{"name":"University of Michigan"},{"name":"University of Michigan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jennifer M.","family":"Ross","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/00cvxb145","id-type":"ROR","asserted-by":"publisher"}],"name":"University of Washington"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Achilles","family":"Katamba","sequence":"additional","affiliation":[{"name":"Uganda Tuberculosis Implementation Research Consortium"},{"id":[{"id":"https:\/\/ror.org\/03dmz0111","id-type":"ROR","asserted-by":"publisher"}],"name":"Makerere University, College of Health Sciences"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David W.","family":"Dowdy","sequence":"additional","affiliation":[{"name":"Uganda Tuberculosis Implementation Research Consortium"},{"name":"Department of Epidemiology"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2025,9,26]]},"container-title":["Epidemiology and Infection"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.cambridge.org\/core\/services\/aop-cambridge-core\/content\/view\/S0950268825100605","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,10]],"date-time":"2025-10-10T07:32:46Z","timestamp":1760081566000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.cambridge.org\/core\/product\/identifier\/S0950268825100605\/type\/journal_article"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025]]},"references-count":0,"alternative-id":["S0950268825100605"],"URL":"https:\/\/doi.org\/10.1017\/s0950268825100605","relation":{},"ISSN":["0950-2688","1469-4409"],"issn-type":[{"value":"0950-2688","type":"print"},{"value":"1469-4409","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025]]},"assertion":[{"value":"\u00a9 The Author(s), 2025.
