Technical Notes

There are many factors that influence how many cases are reported to the health unit, as explained on the Infectious Diseases page.

Provincial definitions classify cases as confirmed, probable or suspect based on clinical and/or laboratory diagnostic criteria. The provincial case definition for pertussis changed in April 2009 to include a definition for probable cases whereas before there was no such classification. The definitions of confirmed and probable cases from 2009 onwards are comparable to confirmed cases before 2009.
