On March 24, as India marks World Tuberculosis Day, the official messaging strikes a familiar note of resolve. The global theme this year calls for country-led action backed by community participation. It is an appeal that fits India’s context, where the burden of tuberculosis remains among the highest in the world despite years of targeted programmes.

Overcrowded living conditions, undernutrition, and gaps in early detection sustain its spread. While the government’s elimination target has pushed TB higher up the policy agenda, the gap between intent and outcomes is still visible on the ground.

There have been gains. Expanded screening, the use of rapid diagnostic tools, and incentives for treatment adherence have improved case detection in several regions. Community health workers have played a critical role in tracing patients and ensuring continuity of care. Yet, the system continues to grapple with missed cases, delayed diagnosis, and the stigma that keeps many from seeking timely treatment.

India’s TB response cannot rely on periodic campaigns alone. It requires a steady strengthening of
