Key findings
- Although the hepatitis B vaccination program is successfully reaching coverage of over 90% among infants, there are still an estimated 1,770 cases of hepatitis B occurring annually. The modelled estimate of
hepatitis B incidence in Australia has remained relatively stable over the period of the national strategies. - The weak evidence available suggests that hepatitis C incidence is stable to decreasing over the time frame of the national strategies.
- Gonorrhoea is a two‑pronged epidemic: among men who have sex with men (MSM) in urban areas and among young Aboriginal people in remote areas. Uncertainties over trends in gonorrhoea testing make notification data a poor indicator for incidence. However, the available evidence for gonorrhoea incidence suggests that incidence has increased for MSM over the past four years.
- Chlamydia notifications have increased substantially, in alignment with increased testing. The available evidence for chlamydia incidence is weak, but suggestive that incidence has been stable or slightly increasing over the past four years.
