STI cases Surge Across Australia
Australia’s 2024 sexual health report reveals a concerning increase in common sexually transmitted infections (STIs), while diagnoses of human immunodeficiency virus (HIV) have declined. The report, released Monday by the university of New South Wales’ Kirby Institute, indicates a significant trend over the past decade.
Syphilis and gonorrhea cases have more than doubled, wiht 5,866 syphilis diagnoses and 44,210 gonorrhea diagnoses recorded in 2024. These findings were presented at the Australasian HIV&AIDS Conference in Adelaide.
Concerning Trends and Disparities
Cases of syphilis among women have quadrupled, raising serious concerns about congenital syphilis. As 2015, congenital syphilis cases have more than doubled, resulting in 34 infant deaths, disproportionately affecting Indigenous Australians, according to the report.
Australia’s Chief Medical Officer, Michael Kidd, emphasized the importance of raising awareness.”By raising awareness among Australians, including healthcare professionals, we will help ensure more people get tested and treated for syphilis, so we can stop the spread of the disease,” he stated.
Chlamydia Remains Prevalent, Testing Rates Low
Chlamydia remains the most common STI in Australia, with 101,742 diagnoses in 2024, particularly affecting individuals aged 20-29. Despite the rising STI rates, onyl 16 percent of Australians aged 16-49 have ever been tested for an STI.
HIV Diagnoses Decline, But Vigilance is Key
HIV diagnoses have decreased by 27 percent over the past decade, reaching 757 cases in 2024. Though, a recent slight increase underscores the need to maintain efforts toward Australia’s goal of virtual HIV elimination by 2030.
The report also highlighted that almost one-third of HIV diagnoses in 2024 were late, meaning patients may have lived with HIV for at least four years before diagnosis. This emphasizes the urgent need for more accessible testing options, including self-testing.
