Demographic and clinical information such as pre-treatment symptom duration will be collected from TB confirmed cases detected at both the intervention and control sites using a pre-tested structured questionnaire. Patients' sputum smear status, the radiological findings and treatment outcomes will be recorded from the referrals sites and Directly Observed Treatment Short Course (DOTS) centers in both groups. The investigators will also collect data on the size of the prison cells and on the number of pulmonary TB cases detected in the previous two years before the start of this intervention in both the intervention and control sites to consider for possible adjustments.
