Data source: Ontario HIV Laboratory Cohort
- Individuals in the Ontario HIV Laboratory Cohort were considered to be in care if they received at least one viral load (VL) test in a given year.
- The percent of people with diagnosed HIV living in Ontario who were in care increased slightly over time for both sexes.
- Time from HIV diagnosis to linkage to care has also improved over time for both males and females.
Figure 1 Percent of people with diagnosed HIV living in Ontario who were in care by sex, 2000 to 2015
Trends: Between 2000 and 2015, the percent of people with diagnosed HIV who were in care increased slightly from 82.3% to 87.8% for males and 77.1% to 85.8% for females. See Table 1 below for data and definitions.
Figure 2 Percent of people newly diagnosed with HIV in Ontario who linked to care within three months of diagnosis by sex, 2000 to 2014
Trends: Between 2000 and 2014, the percent of newly diagnosed people who linked to care within three months of diagnosis increased from 66.7% to 83.3% for males and 70.6% to 78.1% for females. See Table 2 below for data and definitions.

|Year||Males: Linked to care (n)||Males: Newly diagnosed (n)||Males: Linked to care (%)||Females: Linked to care (n)||Females: Newly diagnosed (n)||Females: Linked to care (%)|
|Estimate of percent linked to care||“Linked to care” definition (numerator)||“Newly diagnosed” definition (denominator)|
|Main||Record of a viral load test within three months of HIV diagnosis||Nominal HIV-positive diagnostic test and no evidence of previous diagnosis (i.e. no detectable viral load test or CD4 count before diagnosis date, and first VL after diagnosis not virally suppressed)|
Notes: Data provided by Public Health Ontario Laboratories. Individuals missing information on sex were excluded (approximately 0.4%). The year 2015 not included in Figure 2 and Table 2 as some individuals diagnosed in this year would not have had time to link to care. Tables and Figures display main estimates only.
