Tuberculosis remains a major public-health problem in Bangladesh, despite national efforts to improve case identification and treatment compliance. In 1984, BRAC (formerly the Bangladesh Rural Advancement Committee), a national, non-governmental organisation, began an experimental tuberculosis-control programme in one thana (subdistrict). Community health workers screened villagers for chronic cough and collected sputum samples for acid-fast bacillus (AFB) microscopy (phase one). Positive patients received 12 months of directly observed therapy. Phase two (1992-94) included another nine thanas and, in phase three (1995), eight more thanas were included. From 1995, the treatment was an 8-month oral regimen.In 1995-96, we analysed all programme data from 1992 to 1995. First we analysed phases two (12-month therapy) and three (8-month therapy) separately for proportion cured, died, treatment, failed, defaulted, migrated, and referred. Second, we did a cross-sectional survey of tuberculosis cases in more than 9000 randomly selected households in two phase-two thanas and one non-programme thana, and analysed the follow-up of all patients treated in the programme thanas.In the phase-two analysis, 3497 (90
