Epidemiology and Spatial Analysis: The 1854 Cholera Epidemic

How did a single map of London change the way we fight diseases forever? Long before modern computers, Dr. John Snow used spatial data to trace a deadly cholera outbreak to its source, laying the foundation for modern public health and epidemic response. In this text-only course, you will explore the historic 1854 cholera epidemic in Soho to understand the core principles of epidemiology, scientific inquiry, and geographic data analysis. What you'll learn: - Learn the foundational concepts of epidemiology, disease transmission, and public health tracking. - Analyze how John Snow collected, mapped, and interpreted spatial data to identify the Broad Street pump. - Understand the transition from the miasma theory of disease to modern germ theory through scientific observation. - Apply basic spatial analysis and geographic information concepts to modern outbreak mapping. - Explore how data visualization techniques are used to communicate complex health risks to the public. - Practice critical thinking by evaluating historical data sets and drawing evidence-based conclusions. The course begins with key terminology and the historical context of nineteenth-century London, establishing the scientific debates of the era. You will then read through the step-by-step methodology of Snow's investigation, analyzing how his techniques evolved into the modern geographic information systems (GIS) and epidemiological models we use today. This course is designed for absolute beginners interested in public health, history, data science, or geography, with no prior technical prerequisites required.
