Global TB Epidemiology

Since 2007, TB has been the leading cause of death from a single infectious agent. In 2019, there were an estimated 10 million people with TB: 89% were adults, 8.6% were people living with HIV, and two-thirds were from eight countries: India (27%), China (9%), Indonesia (8%), the Philippines (6%), Pakistan (6%), Nigeria (4%), Bangladesh (4%) and South Africa (3%). About 1.7 billion people (23% of the world's population) are estimated to have latent TB infection (LTBI).

The TB Epidemiology video (below) was produced by the Khan Academy (Stanford School of Medicine). The speaker visually details how many lives are affected by TB around the world.
