Key findings
- A total of 1,236 cases of HIV infection were newly diagnosed in Australia in 2013, similar to levels in 2012 when the number of cases was the highest in Australia since the early 1990s. The annual number of new HIV diagnoses has gradually increased over the past 14 years, from 724 diagnoses in 1999.
- HIV continues to be transmitted primarily through sexual contact between men, accounting for 70% of new diagnoses in 2013.
- An estimated 26,800 (plausible range 24,500 – 30,900) people were living with HIV infection in Australia at the end of 2013 (approximately 0.15% prevalence among adults aged older than 15 years).
- Between 13,200 and 19,500 were receiving antiretroviral treatment and had undetectable levels of HIV. This corresponds to 49 – 73% of all people with HIV and 57 – 84% of people with diagnosed HIV infection.
