What this is
Tuberculosis remains the leading cause of death from a single infectious agent. It is curable with a months-long drug regimen, but detection gaps, treatment interruption, HIV co-infection and rising multidrug resistance keep the toll high. The burden is concentrated in India, Indonesia, China, the Philippines, Pakistan, Nigeria, Bangladesh and South Africa.
