World Tuberculosis Day is observed on 24 March because on that date in 1882
- A.The World Health Organization was founded
- B.Robert Koch announced the discovery of the bacterium causing tuberculosis
- C.The first vaccine against tuberculosis was given
- D.The first sanatorium for tuberculosis was opened
Correct answer
Explanation
The correct answer is B, Robert Koch announced the discovery of the bacterium causing tuberculosis. He presented his finding to an audience of physicians in Berlin on 24 March 1882, and identifying the organism opened the way to diagnosis and eventually to treatment of a disease that was then a leading cause of death.
Option A, the founding of the World Health Organization, belongs to 7 April 1948 and is the reason for World Health Day, a different date in this same chapter. Option C, the first vaccination against tuberculosis, came decades after Koch's announcement and has no day named for it. Option D, the opening of a sanatorium, is not the basis of any international observance. The safe pair to remember is Koch on 24 March and the World Health Organization on 7 April.
