"HIV/AIDS remains an issue of concern for Canada. The number of people living with HIV (including AIDS) continues to rise, from an estimated 64,000 in 2008 to 71,300 in 2011 (an 11.4% increase) (Table 1, Figure 1). The increase in the number of people living with HIV is due to the fact that new infections continue at a not insignificant rate which is greater than HIV-related deaths, as new treatments have improved survival. The estimated prevalence rate in Canada in 2011 was 208.0 per 100,000 population (range: 171.0–245.1 per 100,000 population). Nearly half (46.7%) of those living with HIV were men who have sex with men (MSM). Those who acquired their infection through heterosexual contact and were not from an HIV-endemic region comprised the next largest group (17.6%), followed by those who acquired their infection through injection drug use (IDU) (16.9%) and those exposed through heterosexual contact and were also from an HIV-endemic region (14.9%)."
