HIV/AIDS in the US: the importance of local perspectives

Some recent studies, in STI and other journals, have sought to demonstrate the importance of spatial location as a determinant of STI prevalence in its own right (Haley & Cooper (STI); ‘Scoping Location’ (STI/blogs))). On the face of it, Brawner & Schensul appear to share this aim, in their comparative neighbourhood-based case study of multilevel factors affecting HIV transmission […]

Sexually transmitted infections are amongst the fastest spreading high-incidence notifiable diseases in China

Sexually transmitted infections emerge from a recent epidemiological study as a particularly pressing concern for Chinese public health at the present time.  Yang & Li (Y&L) assess trends in incidence and mortality in 45 notifiable infectious diseases across China over the decade since the SARS tragedy in 2003 brought important changes in Chinese public health […]

Location of HIV-2 emergence determined by distribution of indigenous cultural practices of male circumcision

Sousa & Vandamme demonstrate a robust correlation between HIV-2 prevalence at the time of the 1980s surveys and the absence of indigenous practices of male circumcision earlier in the century.  This is a complex and interdisciplinary study, involving some of the earliest large-scale, West African serological surveys of HIV-2 (1980s) and extensive ethnography of the […]

UNAIDS 2016 Report: How a ‘life-cycle’ approach can help the world ‘get on the fast track’ to HIV prevention

‘Get on the Fast Track: a Life-cycle Approach to HIV’ is the latest UNAIDS report, following on from the UN Assembly’s 2016 declaration of commitment to ‘Fast Track’ goals for ending the HIV/AIDS epidemic. The major theme of the ‘life-cycle’ appears to owe much to the findings of the South African CAPRISA study – above […]

Myth or reality? Are social media triggering an explosion in sexually transmitted infections?

On the whole, where STIs are concerned, social media have tended to be considered as a potential force for the good in public health, offering a new resource for the management of HIV patients, or opportunities for disseminating health messages via peer education (Swanton & Mullan (STIs); Peer group education (STIs/blog)).  Recently, however, there have […]

Increased HIV infectivity in the acute phase of infection may be a less important factor in HIV transmission than we thought

Assessing, as far as we can, the preventative impact of ART on HIV transmission dynamics is evidently very important – both to inform judgments about ART initiation (Wayal & Hart (STI); Cohen (STI)), and also, at the policy level, to be able to evaluate the possible preventative gains of ART scale-up (Shafer & White (STI); […]

The varied nature of the US HIV/AIDS epidemic: what makes the South so different?

As of 2011, 38% of all US citizens diagnosed with HIV were from a block of nine states in the south-east, sometimes referred to as “the South”: Louisiana, Alabama, Florida, N. and S. Carolina, Georgia, Texas, Mississippi and Tennessee. Death rates among those living with HIV in this region were, by far, the highest of […]

Tracking the origin, early spread, and ignition of pandemic #HIV-1 through new approaches to phylogenetic analysis

“Distribution of HIV-1 subtypes in a population”, state Mumtaz & Raddad (STI) in a study of the HIV pandemic in the Middle East, “tracks the spread and evolution of the epidemic”.  Various studies covered in our previous blogs have attempted to read the history of the progress of the HIV epidemic through the evidence of […]

“Hispanic” label masks the specificity of the Puerto Rican #HIV problem in US Northeast

Interventions for HIV prevention should be informed by an understanding of the long-term source of infection, and not just by recent distribution (Mishra & Boily (STIs)).  Amongst recent studies that have sought to inform future interventions are investigations of known subgroups thought to be a potential bridge into the wider population – such as migrant […]
