By health region

Data source: Ontario HIV Laboratory Cohort
 

Key points

  • Health regions are aggregations of public health units and their boundaries. See Technical notes for more information.
  • In 2015, the majority of people with diagnosed HIV living in Ontario were residing in Toronto (54.3%), followed by the Central East (12.1%), Central West (10.5%), Ottawa (10.2%), South West (6.8%), Eastern (3.3%) and Northern (2.8%) regions.
  • Cascade indicators were generally lower for people with diagnosed HIV in the Northern region, and slightly lower for those in Ottawa. In 2015, the percent of people with diagnosed HIV who were virally suppressed were as follows (highest to lowest): Central West (80.9%), Toronto (80.7%), Central East (79.3%), Eastern (78.9%), South West (78.8%), Ottawa (76.5%) and Northern (70.6%).
  • Lower cascade estimates in certain health regions may be due to several factors. For example, people with diagnosed HIV living in some regions may be more likely to seek care outside of Ontario. This would lower cascade estimates in these regions as diagnosed individuals in the Ontario HIV Laboratory Cohort who receive care outside of the province are not considered to be in care, on ART or virally suppressed.
  • Data for the year 2015 only are shown below. Trends over time are available elsewhere on this website.

Definitions

Cascade indicator Definition (main)
Diagnosed Nominal HIV-positive diagnostic testor HIV viral load test, and not administratively lost to follow-up after 2 years
In care At least one VL test in a given year
On antiretroviral treatment Documented on ART, or ART status missing and suppressed, on last VL test in a given year
Virally suppressed VL less than 200 copies/mL on last VL test in a given year

 
 
Notes: Data provided by Public Health Ontario Laboratories. Diagnoses assigned to a health region based on their address of residence or, if unknown, the address of the ordering provider. Individuals living out of province (approximately 1% each year) or with missing health region (approximately 0.1% each year) were excluded. ART status documented on viral load test requisition by ordering provider and missing for 17-20% of requisitions. Tables and Figures display main estimates only. A range of plausible values, based on alternative definitions, are available upon request. VL=viral load. ART=antiretroviral treatment.
