Background: Active case-finding is provider-initiated and implies systematic searching for TB in individuals who would not spontaneously present to a health service, and bringing them into care for diagnosis and treatment. Aim: The present study was carried out with the objective to assess the yield and feasibility of active case finding strategy among household contacts of newly diagnosed pulmonary TB cases and to determine risk factors in household contact. Methods: This community-based study with cross-sectional design was conducted among the household contacts of all newly diagnosed microbiologically confirmed pulmonary TB patients registered at Tuberculosis Unit (TU), Nuh. Investigator conducted house to house visit and met respective index case and his/her household contacts to build the rapport. Results: In the present study, there were 55 sputum smear-positive index cases and 356 household contacts of index cases. The most common symptom among screening positive household contacts was cough followed by weight loss. A substantial proportion (83.8%) of symptom positive household contacts were investigated for tuberculosis and among them, 18.9% were found to be positive for tuberculosis. The overall prevalence of TB cases among household contacts was found to be 1.97%. Conclusion: The present study concludes that household contact screening for active case finding for TB is a feasible and efficient tool that can potentially result in earlier diagnosis and treatment of active TB, thus minimizing the severity and decreasing transmission. It can also contribute toward improving treatment outcomes, health sequelae, and the social and economic consequences of TB.
