The Dapivirine Ring: Key learnings from like-product introductions

Vaginal insertion and partial efficacy are two challenges that could affect the uptake and continued use of the dapivirine ring. Analyses of the introductions of other products that share similar characteristics provide useful lessons to inform planning for rollout of the dapivirine ring. This paper provides information for planners, implementers, funders, researchers, trainers, providers of technical assistance and others to build an agenda for introducing the dapivirine ring that addresses these two challenges.

Priorities for Local AIDS Control Efforts (PLACE) Tool Kit

The Priorities for Local AIDS Control Efforts (PLACE) method aims to improve our understanding of the drivers of local HIV epidemics, identify gaps in services available to those most likely to acquire and transmit HIV, and provide evidence to support tailored interventions to reduce transmission. Achieving this goal is a challenge because many people don’t know they have the virus, making the local pattern of new infections almost impossible to detect.

Study finds HIV care, diagnosis barriers for men fueling epidemic among young women

Young women who have sexual relationships with older men often are dealing with inequitable power dynamics, little capacity to negotiate safe sex or to refuse sex, and—therefore —a greater risk of acquiring HIV. In sub-Saharan Africa, adolescent girls and young women are disproportionately affected by HIV, which has led to a heightened emphasis on understanding the characteristics of their male sexual partners. It also points attention to the fact that men are less often reached with HIV testing, care, and continued treatment—the 90-90-90 HIV care cascade.

Sources of social support and sexual behaviour advice for young adults in rural South Africa

Author

While young people in sub-Saharan Africa (SSA) are at greatest risk of HIV acquisition, uptake of HIV prevention interventions among them has been limited. Interventions delivered through social connections have changed behaviour in many settings, but not to date in SSA. There is little systematic evidence on whom young SSA adults turn to for advice. We therefore conducted an exploratory cross-sectional study from whom young rural South Africans received support and sexual behaviour-specific advice.

Supplement: Population mobility - Challenges for universal HIV testing and treatment

Author
Guest Editors: Carol S Camlin, Susan Cassels, Janet Seeley

Several meta-analyses and systematic reviews of the literature examining factors associated with care entry, engagement and retention show that optimal lifelong engagement in HIV care can be threatened by a range of factors at the individual, social, and structural levels. Mobility affects many of the factors found to contribute to delayed entry or lapses in care, including psychological factors (e.g. seeking care away from home because of stigma), clinic characteristics (e.g.

In many settings with high HIV prevalence, fertility rates are also high and women spend a significant proportion of their reproductive years pregnant, postpartum, or breastfeeding. Some, but not all, studies have demonstrated significantly higher HIV incidence during pregnancy. Per sex act analyses contribute an understanding of the absolute and relative risks of HIV transmission, and can provide insight into whether increased risk during pregnancy and postpartum is attributable to biological or sexual behavior changes.

This study sought to assess the prevalence of HIV risk behaviour among sexually active HIV sero-negative individuals in the Tshwane district of South Africa. The study found that a large segment of sexually active people in the Tshwane district of SA have high risk exposure to HIV. The detection of newly diagnosed HIV infections in all study clinics reflects a wide distribution of individuals who are capable of sustaining HIV transmission in the setting where HIV risk behaviour is highly prevalent.
