Nearly 30 years after the World Health Organization (WHO) declared tuberculosis (TB) a public health emergency, TB remains one of the world’s leading infectious disease killers–despite being preventable, treatable, and curable. In 2020 alone, an estimated 10 million people became ill with TB and 1.5 million people died.

In 2018, the United Nations General Assembly High-Level Meeting (UNHLM) on TB established the ambitious target of diagnosing and enrolling an additional 40 million people on TB treatment and enrolling 30 million people on TB-preventive therapy (TPT) by 2022, with a focus on countries with high TB burdens.
