Introduction to Pathogen Genomics in Public Health

Infectious diseases pose a constant challenge to global health, but modern genomic technologies offer unprecedented tools to track, analyze, and combat these threats. Understanding the core concepts of pathogen genomics is now essential for anyone working in public health, healthcare, or epidemiology. This text-based course guides you through the fundamental principles of genomic epidemiology, showing you how molecular data translates into actionable public health decisions. You will learn to interpret sequencing data, understand how pathogens evolve, and see how genomic surveillance is used to stop outbreaks in their tracks. What you'll learn: - Understand the foundational biology of pathogens and how their genetic material is sequenced. - Differentiate between modern sequencing technologies and key data formats like FASTA and FASTQ. - Analyze how mutations accumulate in pathogen genomes and what they mean for disease transmission. - Interpret phylogenetic trees to trace the evolutionary history and spread of infectious agents. - Apply genomic surveillance concepts to real-world public health investigations and outbreak responses. - Evaluate the ethical and logistical challenges of sharing genomic data globally. The course begins with essential terminology, covering the basic structure of DNA/RNA and sequencing concepts, before progressing to practical applications of genomic epidemiology. You will engage with clear written explanations and conceptual exercises designed to solidify your understanding. This course is designed for absolute beginners, public health professionals, students, and healthcare workers looking to build a solid foundation in genomic epidemiology without any prior coding or bioinformatics experience.
