Most Likelier readers in the US, Western Europe, Japan, or Australia would guess their personal odds of dying from TB at essentially zero, and for them that guess is roughly correct. What the same readers almost universally get wrong is the global picture: TB has been the world’s leading infectious-disease killer for most of the past decade, it regained that title from COVID-19 in 2023, and it kills roughly twice as many people every year as HIV/AIDS.
