The Agency produces three types of estimates as part of its mandate to monitor HIV trends in Canada: Incidence: The number of new HIV infections in a one year period; Prevalence: The number of people living with HIV (including AIDS) at a specific point in time; Proportion undiagnosed: The proportion of people living with HIV who have not been diagnosed, and therefore are not aware of their H [...] Understanding HIV incidence, the rate at which new infections is occurring in Canada, is critical for tracking the leading edge of the epidemic, for planning HIV prevention programs, and for evaluating the impact of existing prevention programs. [...] The estimate of 6,850 Aboriginal people living with HIV at the end of 2014 represents an increase of 12.1% from the 2011 estimate of 6,110. [...] The Agency estimates that 16,020 (range between 13,000 and 19,000) people were living with undiagnosed HIV in Canada at the end of 2014, representing 21% of all people living with HIV in Canada at that time. [...] Since new HIV treatments have reduced HIV mortality and new infections continue to occur at a rate greater than the number of deaths of people living with HIV, the overall number of Canadians living with HIV infection will likely continue to increase in the years to come.
