Topic: Robert Koch

Dr. Andrew Kaufman explains Koch’s Postulates, a set of four criteria designed to establish a causative relationship between a microbe and a disease. He asserts that these common-sense rules have never been strictly satisfied for any infectious virus. The discussion questions the scientific validity of modern virology based on the alleged failure to isolate and purify pathogens from healthy hosts.

The guests describe historical experiments where healthy individuals failed to contract the flu despite being coughed on by sick patients. They also critique Koch's Postulates, noting that the specific bacteria associated with diseases like tuberculosis or diphtheria are not always present in symptomatic patients. These discrepancies are used to argue that the germ theory of disease is unscientific.
