HIV

Human immunodeficiency virus (HIV) is a virus that attacks the immune system. Without treatment, HIV causes acquired immunodeficiency syndrome (AIDS). HIV is transmitted sexually, by blood-to-blood contact including through injecting drug use, and from mother to child.

  • There were 552 new HIV diagnoses in 2021. This represents a decline of 48% over 10 years.

  • While long term trends suggest HIV is declining in Australia, the decline in HIV notifications in 2021 is likely strongly influence by COVID-19, including changes to sexual behaviour, healthcare access and testing practices, and travel.

  • Among gay and bisexual men, HIV diagnoses have declined by over 52% between 2012 and 2021.

  • The numbers of new HIV diagnoses among heterosexuals and people born overseas remained steady between 2012 and 2019 but declined between 2019 and 2021.
