Case definitions: Nationally notifiable diseases

From Public Health Agency of Canada

Case definitions for nationally notifiable diseases are intended to support public health activities rather than clinical diagnosis. Standardized case definitions for NND were first developed through a federal/provincial/territorial process in 1991, with subsequent editions in 2000 and 2009. Following the 2009 revision, the decision was taken to make future updates on a case-by-case basis.
