Case definitions: Nationally notifiable diseases
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.
Previous case definition documents can be found at the following links:
