| - | National surveillance systems in Canada and the United states have been used to observe the trends in AIDS and HIV. In 2005 AIDS diagnosis rates in the United states were substantially higher in blacks, followed by hispanics and then caucasians. In Canada, the AID diagnosis were higher for aboriginal peoples, then blacks, and substantially lower for caucasians. In both countries the trend was seen that HIV diagnosis increased for men who were having sex with men, and in general men were diagnosed at substantially higher rates than women. The age group with the highest rate of diagnosis was 30-39. In Canada, the rates peaked in 1984-1985, which is associated largely with the male homosexual population increase. After 1985, a steady decrease is seen until the early 1990s which was followed by another peak during 1996 and 1997. This peak can be linked back to the high infection rates among the injection drug users population. Incident infections may have increased somewhat since the late 1990s, but there is a great deal of uncertainty associated with recent incidence estimates and if present, this increase is much less than that seen in the early 1980s. At any rate, it can be stated with more certainty that diagnosis rates have not decreased in recent years. There is a need for prevention efforts in order to reduce the diagnosis rates, especially in ethnic minorities, as well as men who have sex with men. | + | National surveillance systems in Canada and the United states have been used to observe the trends in AIDS and HIV.
