Tuberculosis (TB) is the leading cause of death from a single infectious agent, and among the top 10 causes of death, according to the WHO. In 2024, over a million people died from TB, making it a significant public health challenge.

The disease burden, however, is skewed. Over a quarter of the world’s estimated TB cases are in India — each year, approximately 2.7 million new cases are being reported.
