World TB Day - Why 24th March?

World Tuberculosis Day, falling on 24 March each year, is designed to build public awareness that tuberculosis today remains an epidemic in much of the world, causing the deaths of about 1.7 million people each year, mostly in the third world. 24 March commemorates the day in 1882 when Dr Robert Koch astounded the scientific

community by announcing that he had discovered the cause of tuberculosis, the TB bacillus. At the time of Koch's announcement in Berlin, TB was raging through Europe and the Americas, causing the death of one out of every seven people. Koch's discovery opened the way toward diagnosing and curing tuberculosis.

In 1982, on the one-hundredth anniversary of Dr Koch's presentation, the International Union Against Tuberculosis and Lung Disease (IUATLD) proposed that 24 March be proclaimed an official World TB Day. In 1996, the World Health Organization (WHO) joined with the IUATLD and a wide range of other concerned organizations to increase the impact of World TB Day.
