1996 July Australian HIV Surveillance Report

The Australian HIV Surveillance Report has been published on a quarterly basis from July 1990. Reports published from January 1994 are available below. Each report includes article(s) on topics of general interest in the epidemiology of HIV and related infections updates on the number of cases of newly diagnosed HIV infection and AIDS in Australia estimates of HIV incidence and prevalence among people seen through a network of sexual health clinics in Australia.

The Australian HIV Surveillance Update provides a brief summary of HIV and AIDS diagnoses in the most recent quarter, the most recent year and cumulative counts. The Australian HIV Surveillance Update was published separately prior to the July 2000 issue of the Australian HIV Surveillance Report. Updates post April 2000 are included in the Australian HIV Surveilance Report.

Key findings
  • This report presents some of the highlights of the Vancouver AIDS Conference, with a particular focus on epidemiology.
  • At a satellite symposium held just prior to the Conference, the global cumulative number of infections in adults was reported to have more than doubled since the beginning of the decade, from about 10 million cases in 1990 to 25.5 million cases in July 1996. In 1995, 2.7 million new cases of HIV infection were acquired: 1.4 million in sub-Saharan Africa and 1 million in South East Asia. By July 1996, 21.8 million adults and children were living with HIV infection or AIDS, with over 90% in developing countries. Of adults living with HIV infection, 12.2 million (58%) were males and 8.8 million (42%) were females.
  • In many industrialised countries, particularly those in which the epidemic hasbeen due predominantly to sexual transmission between men, annual AIDS incidence has reached a plateau. An increasing proportion of HIV and AIDS diagnoses among women was also observed.
  • The prevalence of HIV infection among pregnant women was 0.3 per 1,000 in Canada, 3 per 1,000 in Brazil, 1.2 per 1,000 in the United States, 20 per 1,000 in Thailand and 300 per 1,000 in Zimbabwe.
  • To date, 10 subtypes of HIV-1 have been identified. In a sample of 215 cases of asymptomatic HIV infection in Thailand in 1994 – 1995, the majority (81%) of infections were subtype E.
