Germ Theory of Disease
Germ theory is the principle that specific microorganisms — bacteria, viruses, fungi, and parasites — cause specific diseases, replacing the ancient miasma theory that attributed illness to bad air or cosmic influences.
Overview
Championed by Pasteur, Koch, and Lister in the 19th century, germ theory made infectious diseases preventable through sanitation and vaccination, and treatable through antimicrobial intervention. Koch's postulates established a rigorous logical framework for proving causation — transforming clinical medicine from empirical art toward experimental science.
Why it matters
Germ theory revolutionized medicine and society: sewage systems, clean water supplies, and food safety regulations followed directly from applying it to city management, reducing mortality on a civilizational scale. It created the public health profession and transformed how governments conceptualize their responsibility for population health.
