World Tuberculosis Day

Celebrated on 03/24/2026

Quick Fact

World Tuberculosis Day is observed on March 24th each year to commemorate the date in 1882 when Dr. Robert Koch announced his discovery of Mycobacterium tuberculosis, the bacterium that causes TB. Despite being preventable and curable, TB remains one of the top infectious killers worldwide, with over 1.5 million deaths annually.

Origins and Establishment of World Tuberculosis Day

World Tuberculosis Day was first observed in 1982, exactly 100 years after Dr. Robert Koch's groundbreaking discovery of the TB bacillus. The day was established by the International Union Against Tuberculosis and Lung Disease (IUATLD) and the World Health Organization (WHO) to raise public awareness about the devastating health, social, and economic consequences of tuberculosis, and to step up efforts to end the global TB epidemic.

Evolution and Modern Commemoration

Since its inception, World Tuberculosis Day has evolved into a global campaign that mobilizes governments, health organizations, and communities. Each year, WHO selects a theme to highlight specific aspects of TB control, such as 'It's Time' (2018) or 'Yes! We Can End TB!' (2023). Activities include educational events, free screening camps, media campaigns, and advocacy for increased funding. The day also serves as a platform to celebrate successes and push for new commitments to achieve the WHO End TB Strategy targets.
