Figure 2 is a graph that illustrates the estimated number of HIV prevalent infections in Canada from 1975 to 2011. The estimated number of HIV prevalent infections is depicted using a low estimate, a point estimate and a high estimate. The point estimate of HIV prevalent infections has grown steadily from 1975 to 2011 (0 to 71,000) with a short plateau between 1994 and 1997 where numbers remained around 40,000. The variation between the low estimate and the point estimate varies from 0 in 1975 to approximately 11,000 in 2011. The variation between the point estimate and the high estimate also varies from 0 in 1975 to approximately 11,000 in 2011.

Figure 3 is a graph that depicts the number of positive HIV tests reported to the Public Health Agency of Canada between 1996 and 2011. The number of positive HIV tests were at their highest in 1996 (2,729) and at their lowest in 2012 (2,062). The number of positive HIV tests reported to the Public Health Agency of Canada declined steadily between 1996 and 2000 before climbing back and levelling off between 2002 and 2007 (remaining at approximately 2,500), the numbers increased slightly in 2008 and has declined each year since.

Figure 4 is a graph illustrating the estimated number of new HIV infections in Canada from 1981 to 2011 by exposure category. The highest numbers were seen in the MSM exposure category with approximately 2,000 in 1981, rising sharply to a peak in 1984-86 of approximately 3,000, and dropping off to approximately 800 in 1999 before rising slowly to approximately 1,500 in 2005, and remaining there until 2011. The numbers of intravenous drug users rose steadily from 0 in 1981 to approximately 1,000 in 1987-90 before declining to approximately 500 in 2011. Heterosexual/non-endemic incidence of new HIV infections increased gradually from 0 in 1981 to approximately 600 in 2011, while heterosexual/endemic incidence of new HIV infections has also gradually increased from 0 in 1981 to approximately 500 in 2011.
