Topic overview

Start with the big picture

Investigating an outbreak involves a series of connected steps rather than a single action. An organized approach helps investigators move from recognizing a possible outbreak toward understanding its scope and circumstances, then using findings to inform response and communication. The exact work required can depend on the situation, so the sequence serves as a framework for investigation rather than a rigid formula. This topic focuses on the overall steps and how they fit together. It is an introduction to the subject; the full lesson provides a more detailed account of the investigation process and its practical considerations.
