1999 April 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
  • By the end of 1997, ninety five cases of HIV infection among health care workers following a specific occupational exposure to blood or body fluids had been documented globally, including five cases in Australia.
  • The estimated risk of hepatitis C transmission was substantially higher than the risk of HIV transmission following percutaneous exposure to infected blood; in cases where the source patient had detectable hepatitis C viraemia, the risk of transmission was 6.1% (95% confidence interval 2.2%, 10.0%).
  • Information on the characteristics of occupational exposures to blood or body fluids was received from 13 sites for the reporting period 1 July to 31 December 1995, 27 sites in 1996 and 56 sites in 1997.
  • The total number of occupational exposures reported in 1995 was 532 (434 (82%) percutaneous), 1,572 exposures in 1996 (1,283 (82%) percutaneous) and 3,092 exposures (2,565 (83%) percutaneous) in 1997.
  • In 1997 the most frequently reported occupational exposures were hollow bore (38%) and other percutaneous (22%) exposures to blood, and splash exposures to the eye (19%).
