RESUMO
Introduction: Tuberculosis is an infectious disease caused by the bacillus Mycobacterium tuberculosis. It mostly affects the lungs (pulmonary TB) and sometime affect other sites (extra pulmonary TB). The disease is spread when people who are sick with pulmonary TB expel bacteria into the air by coughing. Overall, a relatively small proportion (5–15%) of the estimated 1.7 billion people infected with M. tuberculosis will develop TB disease during their lifetime. Objective: To assess the treatment outcome of tuberculosis patients registered under Revised National Tuberculosis Control Programme (RNTCP) and to find out spatial pattern of tuberculosis patients. Materials and Methods: A retrospective record based study was conducted based on the secondary data pertaining to the patients registered at six different tuberculosis units (TU) and 29 designated microscopic centers (DMC) in Sonbhadra district during the period from 2005 to 2015. Results: Overall 85.8% were new cases and among them 80.0% were as pulmonary cases observed. Sputum conversion rate of new sputum-positive case at 2 or 3 months after treatment was 89.9%. Cure rate for new sputum-positive pulmonary TB cases was 84.9% and out of all smear-positive cases, it was 62.4%. Default among new smear-positive cases was 5.5%. Conclusion: The observed treatment success rate in form of cured and treatment completed (91.5%) reveals that the DOTs as an effective strategy for tuberculosis treatment may be classified as better alternative for area like Sonbhadra.
