Scientific schematic showing how changes in disease agents, exposure, transmission, susceptible hosts, and environmental conditions can increase disease above expected levels.

An epidemic is a rise in disease cases above expected levels in a population. Learn its causes, types, examples, and differences from endemic and pandemic.
