About World Tuberculosis Day

World Tuberculosis Day, often shortened to World TB Day, is observed on 24 March under the World Health Organization’s global health campaign framework.

The day raises awareness of tuberculosis and of the health, social and economic consequences associated with the disease, while supporting sustained public-health action to prevent, diagnose and treat TB.

Why World Tuberculosis Day matters

TB is an infectious disease and requires evidence-based public-health and medical care. An awareness page should encourage reliable information and access to qualified health services rather than self-diagnosis or individualized treatment advice.

The observance also highlights that social conditions, access to care, stigma and health-system capacity can affect whether people are diagnosed and treated promptly.

History of World Tuberculosis Day

The first World TB Day was held on 24 March 1982, marking 100 years since Robert Koch announced his discovery of the bacterium that causes tuberculosis. The International Union Against Tuberculosis and Lung Disease, now The Union, proposed the annual commemoration.

WHO records that World TB Day had been celebrated since 1982 but that WHO gave its full support as a coordinating health agency from 1996. On 13 May 1997, the World Health Assembly adopted WHA50.21 and requested the WHO Director-General to coordinate the observance on 24 March each year.

The date continues to connect the history of the 1882 discovery with sustained public-health action against tuberculosis.
