The Revised National Tuberculosis Control Programme (RNTCP) was launched in 1997 based on the WHO DOTS strategy, with a goal of covering the entire country by 2006. RNTCP implements the five components of DOTS - sustained political commitment, quality-assured diagnosis, standardized short-course treatment, uninterrupted drug supply, and standardized recording and reporting. Objectives include achieving at least 85% cure rate of infectious cases through DOTS and detecting at least 70% of estimated cases through quality sputum microscopy and case finding activities.
