In this episode, we’ll discuss Louis Pasteur’s revolutionary contributions to understanding disease transmission. Before his work, many scientists believed in spontaneous generation, thinking microbes arose from disease rather than causing it. Competing theories suggested contagion through direct contact or airborne miasma as disease vectors. Pasteur's experiments demonstrated that airborne germs were responsible for fermentation and spoilage, leading to his Germ Theory in 1861, which asserted that germs cause infections. Although initially met with resistance, Pasteur's research and advancements in microscopy ultimately established the Germ Theory as a cornerstone of modern medicine.
