On Oct. 29, 2024, the World Health Organization (WHO) published a report on tuberculosis revealing that approximately 8.2 million people were newly diagnosed with TB in 2023 – the highest number recorded since WHO began global TB monitoring in 1995. This represents a notable increase from 7.5 million reported in 2022, placing TB again as the leading infectious disease killer in 2023, surpassing COVID-19.

WHO’s Global Tuberculosis Report 2024 highlights mixed progress in the global fight against TB, with persistent challenges such as significant underfunding. While the number of TB-related deaths decreased from 1.32 million in 2022 to 1.25 million in 2023, the total number of people falling ill with TB rose slightly to an estimated 10.8 million in 2023.

A significant number of new TB cases were driven by 5 major risk factors: undernutrition, HIV infection, alcohol use disorders, smoking (especially among men), and diabetes. Tackling these issues, along with critical determinants like poverty and GDP per capita, requires coordinated multisectoral action.
