Background:

It is estimated that approximately half of new HIV diagnoses among heterosexual migrants in Victoria, Australia, were acquired post-migration. We investigated the characteristics of phylogenetic clusters in notified cases of HIV among heterosexual migrants.

Conclusion:

Migrants appear to be at elevated risk of HIV acquisition, in part due to intimate relationships between migrants from the same country of origin, and in part due to risks associated with the broader Australian HIV epidemic. However, there was no evidence of large transmission clusters driven by heterosexual transmission between migrants. A multipronged approach to prevention of HIV among migrants is warranted.

Changing Epidemiology of Gonorrhea in Adelaide, South Australia.

Sex Transm Dis. 2020 Jun;47(6):402-408. doi: 10.1097/OLQ.0000000000001162.

Abstract

Background: Gonorrhea is a significant public health concern. The changing epidemiology of gonorrhea in Australia has highlighted the need for detailed examination of surveillance data to determine population groups at greatest risk for infection.

Methods: We analyzed deidentified gonorrhea notification data for the years 2012 to 2017, in Adelaide (N = 3680), calculating age-adjusted notification and antibiotic resistance rates. Age, gender, year, sexual orientation, and socioeconomic status were assessed for associations with gonorrhea notifications using negative binomial, log binomial and spatial autoregressive models. Maps were generated to examine spatial localization of gonorrhea rates in Adelaide.

Results: Gonorrhea notification rates in Adelaide increased annually, with a 153% adjusted increase in rates from 2012 to 2017, localized to specific areas and inversely associated with income levels. The increase in rates in 2016 and 2017 was associated with young heterosexuals from low income areas. Azithromycin-resistant notifications increased significantly in 2016 in young heterosexuals. Reinfections were significantly more likely in men who have sex with men than other population groups.

Conclusions: This study demonstrates the changing epidemiology of gonorrhea in Adelaide from a largely men who have sex with men profile toward an increase in young heterosexual gonorrhea. This could be seen as a harbinger for future increases in heterosexually transmitted HIV and other sexually transmitted infections in Australia.

Multiple factors explain why middle-aged heterosexuals with new sexual partners don’t use condoms

nam/aidsmap

New strategies and approaches are needed to address the sexual health needs of middle-aged heterosexuals starting new relationships, research published in Sexually Transmitted Infections suggests.

The UK study involved men and women aged between 40 and 59 years with, or considering, new sexual partners after the break-up of a long-term relationship. In-depth interviews showed that beliefs about sexual risk were frequently based on past rather than current circumstances and that individuals often felt that existing sexual health services were geared towards the needs of younger people.

Could It Be HIV? Video for GPs

Thorne Harbour Health, November 2017

‘Could it be HIV?’ features of the story of Abby Landy, whose story is all-too-common for the many individuals who are given a late HIV diagnosis.

Produced with the support of ViiV healthcare, this video encourages clinicians and doctors to ‘consider HIV’. This clip also features Professor Jenny Hoy from Alfred Health.

“This video is vital. We shouldn’t be missing opportunities to diagnose HIV. With a late diagnoses, there is already substantial damage to the immune system. Diagnosing HIV in a timely manner is paramount — for the benefit of the individual as well as the benefit of the broader community’s health and wellbeing.” – Jenny Hoy

HIV diagnoses in Australia drop to lowest number in 18 years: report

Kirby Institute, July 3rd, 2019

Australia continues to lead the world in HIV prevention and in 2018 recorded the lowest number of HIV diagnoses since 2001.

According to a report released today by the Kirby Institute at UNSW Sydney, last year there were 835 HIV diagnoses across the country, which represents a decline of 23% over five years.

The declines reported today are largely due to reductions in the number of HIV diagnoses that are reported as attributable to sex between men. Over the past five years, HIV diagnoses have reduced by 30% among this population.

The report reveals no declines among heterosexual populations, with new diagnoses relatively stable among this group.

Similarly, there have been no declines in HIV diagnoses among Aboriginal and Torres Strait Islander populations.

80% of new HIV cases transmitted by undiagnosed or untreated people

Healio, March 18, 2019

In 2016, more than 80% of new HIV infections in the United States were transmitted by individuals who either did not know they were infected with HIV or had been diagnosed but were not receiving care, according to data released on the first day of the National HIV Prevention Conference in Atlanta.
