Did you know that March 24th is World TB Day? This important annual event commemorates the date in 1882 when Dr. Robert Koch announced his discovery of Mycobacterium tuberculosis, the bacillus that causes tuberculosis (TB).

We produced this graphic for museum visitors that looks at the differences between TB and Covid, and the causes, symptoms, and effects of both.
