HIV/AIDS is a major global public health issue, with an estimated 40.8 million people living with HIV worldwide as of 2024. In Australia, the prevalence of HIV infection has remained low in the general population, with an estimated prevalence of 0.1% in 2017. However, there is still a significant impact on young people and specific at-risk groups. In 2015, 2.1% of all new HIV diagnoses in Australia were among individuals 19 years of age or younger, with the majority (86.3%) between 13 and 19 years old. The decline in HIV notifications since 2020 is likely influenced by COVID-19, with changes in sexual behaviour, healthcare access, and testing practices. The stigma associated with HIV diagnosis, particularly among women, remains a challenge in Australia, leading to unwanted disclosure and mental health issues. Australian researchers and organisations have been actively involved in HIV/AIDS research and advocacy since the early 1980s, contributing to global efforts to address this public health threat.

What You'll Learn
HIV/AIDS stigma and women
HIV/AIDS is relatively uncommon in Australia, with a prevalence of just 0.1% in 2017. However, despite the low numbers, the impact of HIV/AIDS stigma on women cannot be understated. Women diagnosed with HIV/AIDS in Australia often face unwanted disclosure of their health status due to a lack of awareness and knowledge about the disease in the general population. This can lead to emotional and psychological problems, especially for pregnant women, who may experience increased stress, uncertainty, and feelings of shame and guilt. The stigma associated with HIV in women often involves assumptions that they are part of the sex trade industry, are homosexual, or are intravenous drug users. These women are often viewed as contagious and are assumed to have devious traits and behaviours.
The social stigma of HIV/AIDS can lead to discrimination and marginalisation, making it difficult for women to integrate back into their communities. HIV-positive pregnant women may also face barriers to accessing medical support and treatment, which can have significant physical, psychological, and economic side effects. The fear of stigma and discrimination may even prevent pregnant women from participating in PMTCT programs or seeking necessary psychiatric attention.
Self-stigma, or internalised stigma, can also occur when people living with HIV hold negative beliefs about the disease and stigmatise themselves. This can lead to feelings of shame and low self-esteem, which can be more detrimental than external stigma. However, some women have shared inspiring stories of overcoming self-stigma and leading full, healthy lives, advocating for openness and courage in fighting the stigma associated with HIV/AIDS.
To effectively respond to the HIV/AIDS epidemic, it is crucial to address the stigma associated with the disease. While stigma reduction efforts may be complex and challenging, they are necessary to improve the effectiveness of prevention and treatment programs. By increasing awareness and understanding of HIV/AIDS, we can reduce the stigma surrounding the disease and empower those affected to seek the support and treatment they need.

HIV research in Australia
Australia has contributed significantly to the world's knowledge about HIV infection, especially in the areas of pathogenesis, clinical medicine, virology, and viral immunology. The country's history of outstanding research in these fields was well-established even before the arrival of HIV.
The Kirby Institute, based at the University of New South Wales, is the most prominent research organisation in Australia. It focuses on epidemiology, clinical research, and clinical trials, as well as preparing annual national surveillance reports on the disease. The Kirby Institute has contributed significantly to the health and lives of people impacted by HIV, both in Australia and globally. Their research has informed global treatment guidelines, revolutionised HIV prevention, and increased access to essential drugs for people with HIV.
Other research centres in Australia that investigate different facets of HIV/AIDS include the National Centre in HIV Social Research (NCHSR), the Australian Centre for HIV and Hepatitis Virology Research (ACH2), and the Australian Research Centre in Sex, Health and Society (ARCSHS). Research conducted at these centres has led to important discoveries, such as the identification of anal mucus as a significant carrier of the HIV virus, and the development of risk-reduction strategies to reduce the likelihood of transmission during anal sex.
Australia has also been at the forefront of implementing effective disease prevention and public health programs to combat HIV/AIDS. The government recognised and responded to the AIDS pandemic relatively swiftly, with the establishment of needle and syringe programs (NSPs) and the formation of AIDS councils and Drug User Organisations (DUOs). As a result, Australia has achieved and maintained a low rate of HIV infection compared to the rest of the world.
Despite these successes, HIV/AIDS continues to present challenges in Australia. For example, the Bobby Goldsmith Foundation reports that nearly a third of people with HIV/AIDS in New South Wales are living below the poverty line, and stigma and discrimination against people who inject drugs illicitly are reducing access to testing, treatment, and care. However, survival times for people with HIV in Australia have improved over time, thanks in part to the introduction of antiretroviral drug treatments.

HIV in youth
HIV prevalence has remained low in Australia, estimated at 0.1% in 2017, with a total of 38,172 cases diagnosed. The annual number of new HIV diagnoses has decreased by 7% in the last five years, with the majority of diagnoses in males (90%).
In Western Australia, AIDS councils were formed in 1983, and the state has been home to prominent HIV/AIDS research since the early 1980s. The Kirby Institute, based at the University of New South Wales, is regarded as a leading international research institution.
While HIV is declining in Australia, with diagnoses among gay and bisexual men decreasing by over 57% between 2013 and 2022, the virus still affects young people in the country. In 2015, 2.1% of all new HIV diagnoses in Australia were among individuals 19 years of age or younger, with 86.3% of these new diagnoses between 13 and 19 years old. Adolescents and young adults diagnosed with HIV are predominantly male, with male-to-male sexual contact being the predominant risk factor. The median age at diagnosis for this group is 22 years, and they are more likely to be female (21.1%) than older adults (10.8%).
Young adults diagnosed with HIV face unique challenges, including higher rates of loss to follow-up (LTFU) and treatment interruptions compared to older adults. This highlights the need for additional efforts and funding to improve retention in care and provide further support for young people accessing HIV services. The stigma associated with an HIV diagnosis, particularly for women, can lead to emotional and psychological problems, with 42% of women diagnosed also facing a mental health diagnosis.

HIV diagnoses trends
HIV diagnoses in Western Australia have been declining since 2013, with a significant drop in cases among gay and bisexual men, who previously accounted for the majority of diagnoses. The annual number of new HIV diagnoses in Australia decreased by 7% between 2013 and 2017, falling below 1000 annual notifications in 2017. This decline continued, with a 57% reduction in diagnoses among gay and bisexual men between 2013 and 2022.
While the prevalence of HIV in the general population of Australia remains low, estimated at 0.1% in 2017, certain groups are disproportionately affected. Young people, particularly those aged 13-24, represent a small but vulnerable group, with 2.1% of new HIV diagnoses in 2015 occurring in this age group. Adolescents and young adults diagnosed with HIV are mostly male, and male-to-male sexual contact is the predominant risk factor.
The median age of diagnosis for women in Australia was 30 years in 2013, and it is estimated that there were 3,360 women living with HIV by the end of 2021, representing 12% of all people living with HIV in the country. However, women face significant challenges due to the stigma associated with an HIV diagnosis, which often involves assumptions about their involvement in the sex industry, homosexuality, or intravenous drug use. This stigma leads to unwanted disclosure of their health status and contributes to emotional and psychological problems, with 42% of women diagnosed with HIV also being diagnosed with a mental health condition.
The decline in HIV notifications since 2020 is likely influenced by the COVID-19 pandemic, which brought about changes in sexual behaviour, healthcare access, testing practices, and travel. Despite the overall downward trend in HIV diagnoses, there is a need for continued focus on at-risk groups, particularly young people, to ensure retention in care, improved education, and support for those affected.

HIV transmission and prevention
HIV transmission occurs through specific bodily fluids, namely blood, semen, pre-ejaculate, rectal mucus, vaginal fluids, and breast milk. The virus can enter the body through mucous membranes, open cuts or sores, or direct injection into the bloodstream. The most common modes of transmission are through unprotected sexual intercourse, sharing injection equipment, and from mother to child during pregnancy, childbirth, or breastfeeding.
To prevent HIV transmission, it is essential to practice safe sex. This includes consistently and correctly using condoms during sexual intercourse and limiting the number of sexual partners. Pre-exposure prophylaxis (PrEP) is highly recommended for individuals who believe they may be exposed to HIV. Additionally, it is crucial to avoid sharing drug injection equipment and to only use sterile equipment with clean water.
For individuals who have HIV, it is vital to take antiretroviral therapy (ART) or HIV medicine as prescribed by a doctor. ART reduces the viral load in the body, decreasing the risk of transmitting HIV to partners. During pregnancy and childbirth, adhering to HIV treatment can significantly reduce the chances of perinatal transmission to the baby.
HIV prevention also involves regular testing and open communication with partners. Knowing one's HIV status empowers individuals to make informed decisions and take necessary precautions. Seeking care and treatment for HIV is essential for maintaining health and preventing further transmission. By combining safe sexual practices, HIV medicines, and harm reduction strategies for drug use, the risk of HIV transmission can be significantly reduced in Western Australia.
