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.

 

Syphilis Outbreak in Northern South Australia

SA Health, Communicable Disease Control Branch (CDCB),15/5/17

The Communicable Disease Control Branch (CDCB) has been closely monitoring infectious syphilis notifications in South Australia in light of a multi-jurisdictional outbreak of syphilis occurring across northern Australia. It appears that this outbreak has spread to South Australia, with sustained transmission occurring in Port Augusta, and there is the potential for spread to other regions of South Australia.

One in five ‘heterosexual’ men in the UK caught their HIV from another man

nam/aidsmap, 18 February 2017

A genetic analysis of a large database of people with HIV in the UK in care shows that 18% of men with HIV who claim to be exclusively heterosexual in fact belong to clusters of linked infections that consist only of men.

This provides a minimum figure for the proportion of men with HIV in the UK who are what the researchers call non-disclosed MSM (ndMSM).

These ndMSM were considerably more likely to be of black African ethnicity rather than any other ethnic background. They were also very much less likely to have had a recent HIV infection.
