Germ Theory
The theory that infectious diseases are caused by microorganisms (or germs)
Real World Example
During the Industrial Age, 1800-1915, many people lived in crowded cities with poor sanitation, leading to widespread disease. The germ theory, proposed by scientists like Louis Pasteur and Robert Koch, explained that microorganisms (germs) caused these infectious diseases. This understanding was crucial because it led to better hygiene practices, vaccines, and medical treatments, significantly reducing illness and death rates. Today, germ theory remains important as it forms the basis for practices like handwashing, vaccinations, and using antibiotics to fight infections. For example, during the COVID-19 pandemic, understanding germ theory helped people follow precautions like wearing masks and social distancing to prevent the virus from spreading.
