The objective was to describe a large TB outbreak in a company's bar and other leisure settings. A descriptive study of a TB outbreak was carried out. Contacts were studied in the index case's workplace bar (five circles of contacts) and other recreational areas (social network of three bars in the index case's neighbourhood). Chest X-rays were recommended to contacts with positive tuberculin skin tests (TST) (\u2a7e5 mm). The risk of latent tuberculosis infection (LTBI) was determined using an adjusted odds ratio. The dose\u2013response relationship was determined using the chi-square test for linear trend. We studied 316 contacts at the index case's workplace and detected five new cases of TB. The prevalence of LTBI was 57\u00b79% (183\/316) and was higher in the first circle, 96\u00b70% (24\/25), and lower in the fifth, 46\u00b75% (20\/43) (<jats:italic>P<\/jats:italic> &lt; 0\u00b70001). Among 58 contacts in the three neighbourhood bars, two TB cases were detected and the LTBI prevalence was 51\u00b77% (30\/58). Two children of one secondary TB company patient became ill. Bars may be transmission locations for TB and, as they are popular venues for social events, should be considered as potential areas of exposure.<\/jats:p>","DOI":"10.1017\/s0950268817002588","type":"journal-article","created":{"date-parts":[[2017,11,28]],"date-time":"2017-11-28T04:31:26Z","timestamp":1511843486000},"page":"3497-3504","update-policy":"http:\/\/dx.doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":8,"title":["A highly transmissible tuberculosis outbreak: the importance of bars"],"prefix":"10.1017","volume":"145","author":[{"given":"P.","family":"GODOY","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.","family":"ALSED\u00c0","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.","family":"FALGUERA","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"T.","family":"PUIG","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"P.","family":"BACH","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.","family":"MONRAB\u00c0","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.","family":"MANONELLES","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2017,11,28]]},"reference":[{"key":"S0950268817002588_ref25","doi-asserted-by":"publisher","DOI":"10.2169\/internalmedicine.43.263"},{"key":"S0950268817002588_ref23","doi-asserted-by":"publisher","DOI":"10.1183\/09031936.00201609"},{"key":"S0950268817002588_ref17","unstructured":"Centro Nacional de Epidemiolog\u00eda.
