Topic Four
How has society’s understanding of infectious diseases evolved?
This Topic explores how society’s understanding of infectious diseases has evolved from ancient beliefs to scientific explanations.

Introduction to Changing Ideas About Disease
This video highlights the pivotal role of Louis Pasteur, a key figure in the field of immunisation and the founder of germ theory, which transformed our understanding of disease transmission. Pasteur’s work laid the foundation for modern infection control, and his famous motto, “Fortune favors the prepared mind,” underscores the importance of scientific observation and preparedness. This principle continues to inspire advancements in public health, as illustrated by Prof. Robert Booy’s real-world application of immunisation research in the video.
