Tuberculosis

Estimated tuberculosis incidence and mortality by country from 2000 to 2024.

Tuberculosis remains the world's deadliest infectious disease. In 2024, an estimated 10.8 million people fell ill with TB and 1.25 million died, more than from HIV/AIDS or malaria. Nearly a quarter of the world's population carries latent TB infection. The disease is curable and preventable, yet a persistent gap between estimated incidence and detected cases means millions go undiagnosed each year, driving ongoing transmission and preventable deaths. The burden falls hardest on South-East Asia and Africa, which together account for roughly three-quarters of all cases.

This page uses WHO Global Tuberculosis Programme estimates across 217 countries. Each country is shown as three concentric circles: the outer circle is estimated true incidence, the middle circle is detected (notified) cases, and the inner core is estimated deaths. The gap between the outer and middle circles represents undetected cases.
