Pathogen Genomic Epidemiology: Mutations, Transmission, and Phylogenetics

Understanding how infectious diseases spread is critical for modern global health. Genomic epidemiology leverages sequencing data to track pathogens in real-time, offering unprecedented insights into outbreaks and evolutionary patterns. This text-based course guides you through the core scientific principles of pathogen genomics. You will understand how mutations occur, how evolutionary trees are built, and how genomic patterns reveal the hidden pathways of disease transmission. What you'll learn: - Understand the fundamental terminology of pathogen genomics, mutations, and viral or bacterial evolution. - Analyze how genetic variations and mutations serve as molecular fingerprints to track transmission chains. - Interpret phylogenetic trees to reconstruct evolutionary relationships and outbreak origins. - Explore modern phylodynamic concepts to estimate pathogen population growth and spread. - Evaluate public health genomic databases and modern variant tracking workflows used globally. The course begins with foundational definitions of genetic material and evolutionary mechanisms before guiding you through phylogenetic reconstruction and practical transmission analysis. You will engage with written case studies and conceptual exercises to solidify your understanding. This course is designed for public health professionals, biology students, and curious learners seeking a clear, technical introduction to genomic epidemiology without requiring advanced bioinformatics prerequisites.
