1.12 HIV/AIDS, hepatitis & sexually transmissible infections

This measure reports on the rate of notified sexually transmissible and bloodborne virus infections, including chlamydia, gonorrhoea, non-congenital syphilis, newly acquired hepatitis C, newly acquired hepatitis B and HIV/AIDS for Indigenous Australians.

Why is it important?

The bacterial sexually transmissible infections included in this measure are notified cases of chlamydia, gonorrhoea and non‑congenital syphilis. These infections can have potentially serious consequences if left untreated. Hepatitis causes serious illness and can also progress to cirrhosis of the liver, cancer and premature death (ASHA 2016). Sexually transmissible infections can have serious long‑term consequences (Bowden et al. 2002). Several of these infections can cause miscarriage (Campbell et al. 2011).
