A population-based, retrospective cohort of people with diagnosed HIV living in Ontario created using Public Health Ontario Laboratory’s HIV Datamart. It includes people in the datamart who have record of a nominal HIV-positive diagnostic test and/or at least 1 viral load test, and who have not been administratively lost to follow-up. In additional analyses, non-nominal HIV-positive diagnoses are also included in the cohort. More information on the cohort can be found under technical notes
