Evaluating Multi-Jurisdictional Enteric Illness Outbreak Messaging in Canada: A Content Analysis of Public Health Notices.

Effective risk communication during enteric illness outbreaks requires the provision of clear and consistent information to diverse audiences to reduce risk of exposure, inform behavior changes, and prevent illness. Most enteric illnesses are caused by pathogens transmitted through consumption of contaminated food or water, contact with animals, or person-to-person contact. When multi-jurisdictional outbreaks occur, the Public Health Agency of Canada posts web-based Public Health Notices (PHNs) to inform Canadians.
