Davidson 5. Population Health and Epidemiology

Population health shifts the lens from the individual to the many — revealing patterns that no single consultation can show. This chapter explores how disease is measured, prevented, and understood at scale.In this deep dive, you’ll hear how incidence, prevalence, screening, and risk intersect with policy, equity, and ethics. It examines why well-intentioned interventions can mislead, how bias distorts data, and why prevention often requires patience rather than immediacy.This chapter invites clinicians to hold two perspectives at once: the person in front of them, and the population beyond the room.
