Introduction to Epidemics: Pathogen Origins and Disease Control

Infectious disease outbreaks shape our world, but understanding how they start is the first step to preventing the next global health crisis. This text-based course introduces you to the core principles of epidemiology, tracing how novel pathogens emerge and spread. You will transition from a curious observer to someone who understands the scientific mechanisms behind outbreaks, the history of major epidemics, and how modern public health systems respond to emerging threats. What you'll learn: Understand the fundamental terminology and concepts of epidemiology and disease transmission; Analyze the origins and evolutionary pathways of novel pathogens; Examine historical and modern case studies of major global outbreaks; Explore the role of modern genomic surveillance and digital informatics in tracking pathogens; Evaluate prevention, containment, and mitigation strategies used by health organizations. The course begins with foundational definitions of infectious diseases before moving into pathogen biology, historical outbreak analyses, and modern data-driven surveillance methods. This course is designed for beginners, public health enthusiasts, and students seeking a foundational understanding of epidemiology, with no prior medical background required.
