Foundations of Pathogen Genomics for Public Health

Genomic data has revolutionized how we detect, track, and combat infectious diseases. Understanding the core concepts of pathogen genomics is now essential for anyone working in public health, healthcare, or bioscience. This text-based course guides you through the fundamental principles of genomic epidemiology without requiring a background in advanced bioinformatics. You will gain the conceptual framework needed to interpret genomic data and apply it to real-world disease surveillance and outbreak response. What you'll learn: 1. Understand the core biological concepts of pathogen genomes, mutations, and evolutionary lineages. 2. Explore how genomic sequencing technologies decode pathogen DNA and RNA. 3. Analyze phylogenetic trees to track the transmission pathways of infectious diseases. 4. Apply genomic epidemiology principles to investigate localized outbreaks and global pandemics. 5. Evaluate variant surveillance data to inform vaccine updates and public health policy. We begin with essential terminology and the biological foundations of microbial genetics before moving into sequencing methods and phylogenetic analysis. You will progress through written case studies and practical scenarios that simulate real public health investigations. Designed specifically for beginners, this course requires no prior programming experience or advanced science background. It is ideal for public health professionals, students, and curious learners seeking a clear introduction to genomic surveillance.
