This module provides a brief overview of outbreak investigation. After defining common terms, the module walks through common steps in outbreak investigations: verify accuracy of disease reports, determine existence of outbreak, establish a case definition, identify additional cases, conduct descriptive epidemiology, generate/test hypotheses, monitor the course of the outbreak, conduct environmental and lab investigation, implement disease control measures, and communicate findings. For each step, the course describes relevant methods and considerations. The module concluded with information about types of outbreak investigators, methods of detecting outbreaks, and provides tips for running a successful outbreak investigation. Examples, sort exercises, and a final assessment are used to reinforce learning.
