World Tuberculosis Day is a worldwide event that aims to raise public awareness of tuberculosis and the efforts made to prevent and treat this disease. This event is held on March 24 each year and is promoted by organizations such as the World Health Organization (WHO).

World Tuberculosis Day marks the day in 1882 when Dr Robert Koch detected the cause of tuberculosis, the TB bacillus. This was a first step towards diagnosing and curing tuberculosis. World Tuberculosis Day can be traced back to 1982, when the International Union Against Tuberculosis and Lung Disease launched World TB Day on March 24 that year, to coincide with the 100th anniversary of Dr Koch’s discovery.

In 1996, the World Health Organization (WHO) joined the union and other organizations to promote World TB Day. The Stop TB Partnership, called the Stop TB Initiative at the time of its inception, was established in 1998. It is a network of organizations and countries fighting tuberculosis. WHO works with this partnership on to support the activities and events that take place on World Tuberculosis Day each year.

Tuberculosis, or TB, is an infectious bacterial disease caused by Mycobacterium tuberculosis, which most commonly affects the lungs. It is transmitted from person to person via droplets from the throat and lungs of people with the disease.
