Data notes
- Data for 2024 excludes cases that have been previously diagnosed outside of Canada (e.g., prior to immigration) or in another province or territory, when known.
- Data presented do not account for age and sex rate variations between provinces and territories.
- Note that for Manitoba cases, information collected in 2024 about heterosexual sex as a route of exposure or transmission is not reportable in a compatible format. As such, these cases were assigned to other exposure categories; however, heterosexual sex is an important factor in HIV transmission in Manitoba.
- If discrepancies exist between data summarized and provincial or territorial reports, the most recent provincial or territorial report should be utilized.
- TR: territories, AT: Atlantic provinces.

- Based on sentinel surveillance representing 95% of infants who were exposed to HIV.
