Abstract
Sexually transmitted infections (STIs) bear a high burden of disease and, subsequently, high health costs globally. Chlamydia, gonorrhoea, syphilis, and trichomoniasis contribute to nearly one million infections every day worldwide. Sexually transmitted infections continue to be the most frequently notified condition to the Australian National Notifiable Diseases Surveillance System and the numbers continue to increase. Australia has achieved several significant successes in reducing STIs and blood-borne viruses (BBV) including the significant decrease in genital warts in those less than 30 years old since 2007 following the launch of human papillomavirus vaccines in women, the virtual elimination of mother to child transmission of HIV, and the increased uptake of successful hepatitis C treatment following the availability of direct acting antiviral treatment on the Pharmaceutical Benefits Scheme. However, several challenges remain, including the ongoing rise of chlamydia, gonorrhoea, and syphilis over the last five years; the emergence of antibiotic resistance; and the increasing disparity in the prevalence of STIs and BBV in men who have sex with men, young people, and Aboriginal and Torres Strait Islander people, and challenges in the delivery of services to rural and remote Australia. In this paper, we aim to provide a snapshot of the current landscape and challenges for chlamydia, gonorrhoea, mycoplasma, syphilis and HIV infections in Australia.
