BIO-215 People, Places, and Plagues examines the biology and geography of infectious disease, exploring how pathogens, human populations, and place interact to shape the spread and historical impact of epidemics and pandemics.
Disease as biology, geography, and history combined
The course examines infectious disease not just as a biological phenomenon, but as something shaped by geography (where populations live, travel, and interact) and history (how societies have responded to and been transformed by epidemics).
From historical plagues to biological understanding
BIO-215 connects the biological mechanisms of infectious disease to their real historical and geographic consequences, showing how understanding pathogen biology helps explain why certain diseases spread where and when they did.
Key topics in BIO215
- Biology of infectious pathogens
- Geography and the spread of disease
- Historical impact of epidemics and pandemics
- Human population factors in disease transmission
- Public health responses to disease outbreaks
- Case studies of historically significant plagues

Worked example: why geography matters to disease biology
- Biology alone: Understanding how a pathogen infects and spreads at the cellular level
- Biology plus geography: Understanding why that same pathogen devastated one region's population while sparing another, based on trade routes, population density, or climate
- Lesson: BIO-215 teaches that a full understanding of historical plagues requires combining biological mechanism with geographic and social context

Frequently asked questions
The biological mechanisms of how a pathogen infects and spreads only explain part of why historical epidemics unfolded the way they did — factors like population density, trade and travel routes, sanitation, and social response all shaped where and how severely a disease actually spread, meaning a purely biological account would miss much of what made historical plagues so consequential. BIO-215 combines these dimensions because understanding disease's real-world impact genuinely requires this interdisciplinary view.
The same biological, geographic, and social factors that shaped historical plagues — pathogen transmission mechanisms, population movement, public health response — remain directly relevant to understanding modern infectious disease outbreaks and pandemics, meaning the historical case studies function as concrete, well-documented examples of dynamics that still apply today. BIO-215 uses historical plagues as its primary material because they provide clear, thoroughly studied examples of principles that remain applicable to contemporary public health challenges.
