Davidson 13. Infectious Disease

Infectious disease sits at the crossroads of biology, behaviour, and environment. This chapter explores how pathogens interact with hosts, how infections present across organ systems, and why context matters as much as microbiology.In this deep dive, we examine patterns of infection rather than isolated organisms — considering routes of transmission, host susceptibility, and the balance between immune response and tissue damage. You’ll hear how clinical reasoning integrates epidemiology, exposure history, and evolving presentations.This chapter frames infectious disease as a dynamic process, shaped by global movement, inequality, and antimicrobial pressure. It invites clinicians to think systemically, recognising infection not as an isolated event, but as part of a wider ecological and social landscape. This is a public episode.
