HIV rates remain stable, while STIs continue to rise: Australia’s annual report card on HIV, STIs and viral hepatitis

New HIV notifications in Australia have remained stable over the past four years, following a steady increase since 1999, according to the 2016 Australian Annual Surveillance Report into sexually transmissible infections and blood borne viruses, released today by the Kirby Institute at UNSW Australia.

There has been an expansion in the delivery of key HIV services in Australia, resulting in a 27% increase in the frequency of HIV testing over the last five years and a 45% increase in treatment coverage for those diagnosed with HIV in the past decade. Over 90% of people living with HIV and taking antiretroviral treatment now have virus levels that are below detection limits. This means they are likely to remain well and extremely unlikely to transmit HIV to another person.

“We can be very pleased with these results, however in order to achieve the 2020 elimination goals agreed to by health authorities around the world we must continue to enhance our prevention programs, and increase access to new technologies such as home testing kits and preventive drug therapies like PrEP (pre-exposure prophylaxis),” said Associate Professor Rebecca Guy from the Kirby Institute.  

In contrast to HIV patterns in the non-Indigenous population, rates among Aboriginal and Torres Strait Islander men have doubled over the past five years. Ahigher proportion of HIV cases in the Aboriginal and Torres Strait Islander population were among heterosexuals and people who inject drugs, than the non-Indigenous population.

“These increases highlight the importance of a strengthened focus on HIV prevention, including harm reduction initiatives, such as greater access to clean needles and syringes and drug dependency treatment for people who inject drugs, and targeted campaigns for the community focussed on testing, treatment and PrEP in this vulnerable population,” said Associate Professor James Ward from the South Australian Health and Medical Research Institute.

The report also provides an update on sexually transmissible infections in Australia.

At the end of 2015, there were an estimated 260 000 new cases of chlamydia in 15–29 year olds, which means approximately 1 in 20 young people in Australia had chlamydia last year. The vast majority (72%) of new infections in young people are undiagnosed and therefore untreated.

“While there has actually been an encouraging decline in the chlamydia notification rate among 15-19 year olds, the high rates of undiagnosed chlamydia highlight the need for testing to be routinely offered to sexually active adolescents, young adults and their partners,” said Associate Professor Guy.

There were 18 588 notifications of gonorrhoea in 2015, predominantly in men who have sex with men and young Aboriginal and Torres Strait Islander people in remote areas of Australia.  

Over the last ten years rates of gonorrhoea diagnosis have almost doubled, primarily due to an increase in testing. The rise may also relate to increases in condom-less sex among men who have sex with men, linked to the greater availability and awareness of highly effective HIV prevention strategies.

“These findings remind us that we must not lose sight of STI prevention, particularly regular testing and treatment,” said Associate Professor Guy.

Overall, Aboriginal and Torres Strait Islander people continue to experience a disproportionate burden of disease with rates of chlamydia, gonorrhoea and infectious syphilis 3, 10 and 6 times greater than the non-Indigenous population in 2015, with even more substantial differences in remote and very remote areas.

In contrast, over the past nine years there has been a 91% reduction in genital warts in young Aboriginal and Torres Strait Islander females aged less than 21 years, due to the introduction of vaccine programs to adolescents in school. Genital warts were previously a very common sexually transmitted infection caused by the human papillomavirus, but can now be prevented by the same vaccination given to adolescents in schools that is used to prevent cervical cancer.

The full report also contains data on viral hepatitis in Australia, which was released on 29 September ahead of the 10th Australasian Viral Hepatitis 2016 Conference. The press release and supplemental report related to viral hepatitis is available on the Kirby Institute website.
