Decisions and actions rely on a clear and consistent understanding of "diarrhea" and "outbreak" and CCC staff indicated a need for this guidance. Developing one definition may not be possible when there are a number of factors to consider, but inclusion of these factors in a clear decision making framework could be of assistance to staff. It is important for public health officials and management of CCCs to work together while continuing to develop and strengthen definitions of diarrhea and outbreak. As well, it remains an important task to continue to clarify procedures and activities with all CCC staff to ensure consistency.
