This hour-long module provides a brief overview of infectious disease epidemiology. After describing the goals of this field, the module focuses on the concepts of the epidemiologic triangle (agent, host and environment), modes of transmission, communicability, infectivity, pathogenicity, and virulence. The lecture then explains the role of infectious disease epidemiology in descriptive epidemiology, surveillance, and outbreak investigations. Finally, the module explains the concept of immunity, and introduces different forms of disease prevention and control. Examples, short exercises, and a final assessment are used to reinforce learning.
