- In recent years, the number and rate of HIV tests were similar among males and females. In 2017, 50.1% of people tested were males and 49.9% were females, while the HIV testing rate per 1,000 people was 39.8 for males and 38.4 for females. For the first time in 2017, the number of HIV tests among males was greater than the number of HIV tests among females.
- Over the past 10 years, there was a greater increase in HIV testing among males than females. Historically the female HIV testing rate has exceeded the male rate, but the past four years were the first where the HIV testing rate was higher for males. Of note, prenatal HIV tests were not included here and are presented separately in this report.
- While the HIV test positivity rate decreased over time for both sexes, it was consistently three to four times higher among males than females. In 2017, the positivity rate was 0.26% for males and 0.07% for females.
-  The overall population in Ontario is not split equally by sex – there are a higher number of females compared to males.
Figure 1 Number of HIV tests (thousands) by sex, Ontario, 2008 to 2017
Snapshot: Between 2008 and 2017, the number of HIV tests increased over time for both sexes, with a greater increase among males. In 2008, there were almost 30,000 more tests among females compared to males. The difference in the number of HIV tests by sex decreased over time, and for the first time in 2017, there were more HIV tests among males compared to females.

Snapshot: Between 2008 and 2017, there was a decrease in the percent of HIV testing among females.

Notes:Data provided by Public Health Ontario Laboratory. HIV-negative prenatal tests not included. Tests with unknown sex were excluded (approximately 3% each year). Positivity rate refers to the percent of tests that were HIV-positive and includes those being diagnosed for the first time in Ontario after being diagnosed previously elsewhere.
