World TB Day
World TB Day is observed worldwide every year on 24 March — marking the day Dr. Robert Koch announced his discovery of the bacillus that causes tuberculosis, on 24 March 1882. The day is one of the World Health Organization (WHO)'s designated global public-health campaigns. In 2026, the day falls on a Tuesday. This is not a public holiday — schools and offices stay open as usual, in India and worldwide.
This year's dates (2026)
Before Koch's 1882 discovery, tuberculosis was widely believed to be a hereditary disease or one of unclear cause. Koch proved it was an infectious disease caused by a specific bacterium, which opened the path to diagnosis and treatment — at the time, one in every seven deaths in Europe and America was caused by TB, which shows the historical significance of this discovery.
History & significance
On 24 March 1882, Dr. Robert Koch announced his discovery of the TB bacillus before scientists at the Berlin Institute of Hygiene. The discovery won him the 1905 Nobel Prize in Medicine.
To mark the centenary of Koch's discovery, the International Union Against Tuberculosis and Lung Disease (IUATLD) proposed 24 March as "World TB Day" in 1982. WHO and the United Nations, however, gave the day formal annual status more than a decade later — the first formal planning meeting was held in The Hague, Netherlands, in 1995, and widespread global observance began from 1996. Today it is one of WHO's 11 officially designated global public-health campaigns. Koch's discovery (1882), the day's proposal (1982), and WHO's formal recognition (1995-96) are three distinct milestones, roughly a century apart — worth keeping separate.
Public holiday status
World TB Day is not a public holiday — neither globally nor in India. Schools, offices, and hospitals function normally on this day, with special awareness programmes held instead.
How it is observed in India
In India, the day is marked at a national level under the leadership of the Union Ministry of Health and Family Welfare — India's National TB Elimination Programme (NTEP) is directly linked to this day. In 2026, a national-level programme was held under the health ministry's leadership, launching the "TB Mukt Bharat Abhiyaan" — a 100-day special campaign, a dedicated mobile app, and urban-ward-level initiatives — aimed at improving case detection and treatment continuity. India's theme was also aligned with WHO's global theme.
Tuberculosis is a treatable disease — World TB Day's focus is on awareness and access to treatment, not fear.

FAQ
- Why is World TB Day observed?
- It marks Dr. Robert Koch's 24 March 1882 announcement of the bacterium that causes tuberculosis, and is used to accelerate global efforts toward TB elimination.
- Why does World TB Day fall on 24 March specifically?
- Because Robert Koch announced his discovery of the TB bacillus on this exact date, 24 March 1882.
- When did World TB Day begin?
- The IUATLD proposed the day in 1982 (marking the centenary of Koch's discovery); WHO's formal global recognition and widespread observance began only from 1995-96.
- What efforts is India making toward TB elimination?
- India's National TB Elimination Programme (NTEP) is the main initiative in this direction; in 2026, the "TB Mukt Bharat Abhiyaan," a 100-day special campaign, was launched.
- Is there a holiday on World TB Day?
