What were Robert Koch's major contributions to Epidemiology?
Koch made several seminal contributions to epidemiology. One of his most notable achievements was the development of Koch's postulates, a set of criteria designed to establish a causative relationship between a microbe and a disease. These postulates remain fundamental in the fields of microbiology and epidemiology.
Another significant contribution was his discovery of the causative agents of major diseases. In 1876, Koch identified the bacterium Bacillus anthracis as the cause of anthrax. This was followed by his discovery of Mycobacterium tuberculosis, the bacterium responsible for tuberculosis, in 1882 and Vibrio cholerae, the causative agent of cholera, in 1883.
