There are many factors that influence how many cases are reported to the health unit, as explained on the Infectious Diseases page. It is unclear to what extent the global COVID-19 pandemic has influenced the reporting and spread of other infectious diseases – counts and rates of disease since 2020 should be interpreted with caution.
Provincial definitions classify cases as confirmed or probable based on clinical and/or laboratory diagnostic criteria. The provincial case definition for campylobacter enteritis 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. In 2014, Detection of Campylobacter spp. by nucleic acid amplification testing was added under the confirmed case definition. In 2019, this was moved to the probable case definition.
