The Worst Epidemics Throughout History

Tuberculosis (TB)

Tuberculosis is one of the oldest known diseases, with a recorded case of it in a 17,000 years old bison. The disease originated from the animal but transferred it to humans. In the 1800s, about 25% of all deaths were attributed to tuberculosis. It also caused one in sixth deaths in France. However, once sanitation became better, the rates of death decreased dramatically.
