National BBV & STI Surveillance & Monitoring Report 2011

This report provides an annual account of progress against the goals and objectives of Australia’s National Blood‑Borne Virus (BBV) and Sexually Transmissible Infections (STIs) Strategies.

In April 2010, a suite of National Strategies for the prevention and management of Human Immunodeficiency Virus (HIV), sexually transmissible infections, hepatitis B and hepatitis C, including in Aboriginal and Torres Strait
Islander communities were endorsed by the Australian Health Ministers’ Conference. The National Strategies cover the period 2010 – 2013.

The aims of these National Strategies are to:

  • Reduce the transmission of HIV, STIs, hepatitis B and hepatitis C
  • Reduce the morbidity, mortality and personal and social impacts they cause.

This report describes the targets, objectives and indicators of the National Strategies, and the level of progress being made in response. It provides measurement of the effectiveness of our national response and highlights areas requiring attention.

Key findings
  • Although the hepatitis B vaccination program is successfully reaching coverage of approximately 95% among infants, there are still 1530 – 2600 new incident cases of hepatitis B occurring annually.
  • Data indicate that hepatitis C incidence ranges between 5 and 22 per 100 person-years among people who inject drugs (PWID) but there is no evidence of a decreasing or increasing time trend.
  • There is reasonably strong evidence that HIV incidence across Australia has recently stabilised at around 4.6 per 100,000 population after increasing trends. 
  • Gonorrhoea is a two pronged epidemic. The available evidence for gonorrhoea incidence suggests that incidence may be increasing for men who have sex with men, with the notification rate in men increasing 26%
  • to over 60 per 100,000 population.
  • The available evidence for chlamydia incidence is weak, but suggestive that incidence is likely to be slightly increasing. Positivity levels increased by more than 5% in Aboriginal and Torres Strait Islander people and young heterosexual women, and lesser amounts in other priority groups.
