Tuberculosis, the top infectious killer
10.7 million people fell ill with TB in 2024 and 1.23 million died — though deaths have fallen 29% since 2015.
How this affects people
TB is an airborne bacterial disease that is curable, yet remains one of the world's deadliest infections.
It thrives where poverty, undernutrition, HIV and crowded housing meet, and drug-resistant TB is harder and costlier to treat.
