Perceptions of pre-exposure prophylaxis among sexually active adolescent girls and young women in Zimbabwe–A qualitative study
Adolescent girls and young women (AGYW; aged 15–24 years) in Zimbabwe face high risk of contracting HIV. Despite proven effectiveness of Pre-Exposure Prophylaxis (PrEP), its uptake and continuation among AGYW is low. We aimed to explore views on PrEP, norms around sexual behaviour and how programs can improve PrEP uptake among this group. From December 2021 to March 2023 nine focus group discussions were held with 92 (8–12 per group) sexually act…
Who has never tested for HIV following a community-based distribution of HIV self-test kits? Establishing associated predictors in rural Zimbabwe
In 2023, Zimbabwe attained the 95-95-95 UNAIDS targets. However, some sub-populations are substantially less likely to have tested for HIV. Knowledge of characteristics of these groups is crucial in designing interventions that address their needs. We estimated the prevalence and predictors of “never-having tested for HIV” status following community-based distribution of HIV self-test kits in rural Zimbabwe. We analysed data from a household surv…
HIV incidence and prevalence projections for Zimbabwe
Introduction : Understanding how HIV epidemics are likely to behave in the future is key to informing HIV response strategies in low-income countries. Up-to-date HIV epidemiological estimates are important for policy decision- making, but surveillance data can be out of date. This study compared forecasts from HIV epidemiological models. Methods : Five independent modelling groups (EMOD-HIV, Goals, HIV Synthesis, Optima and PopART-IBM) calibrated…
Behaviour changes following HIV diagnosis among men who have sex with men in the era of treatment as prevention
We described the longitudinal changes in sexual behaviour and associated factors among newly diagnosed with HIV men who have sex with men participating in a prospective observational study from a London HIV clinic (2015–2018). Participants self-completed questionnaires at baseline, months 3 and 12. Information collected included socio-demographic, sexual behaviour, health, lifestyle and social support. Trends in sexual behaviours over one year fo…
A quantitative assessment of the consistency of projections from five mathematical models of the HIV epidemic in South Africa
While models produced consistent estimates for several outputs, there are areas of variability that should be investigated. This is important if projections are to be used in subsequent cost-effectiveness studies
Risk of HIV transmission through condomless sex in serodifferent gay couples with the HIV-positive partner taking suppressive antiretroviral therapy (PARTNER)
BACKGROUND: The level of evidence for HIV transmission risk through condomless sex in serodifferent gay couples with the HIV-positive partner taking virally suppressive antiretroviral therapy (ART) is limited compared with the evidence available for transmission risk in heterosexual couples. The aim of the second phase of the PARTNER study (PARTNER2) was to provide precise estimates of transmission risk in gay serodifferent partnerships. METHODS:…
Changes in chemsex and sexual behaviour over time, among a cohort of MSM in London and Brighton
Chemsex and use of two individual chemsex drugs (mephedrone and GHB/GBL) significantly declined over time among individuals in the study, alongside most measures of sexual behaviour with the exception of those related to CLAI. Focusing health promotion and HIV prevention, such as awareness of post-exposure prophylaxis (PEP) and access to pre-exposure prophylaxis (PrEP), on MSM that report chemsex, and in particular problematic chemsex, would be h…
Sexual Activity Without Condoms and Risk of HIV Transmission in Serodifferent Couples When the HIV-Positive Partner Is Using Suppressive Antiretroviral Therapy
IMPORTANCE: A key factor in assessing the effectiveness and cost-effectiveness of antiretroviral therapy (ART) as a prevention strategy is the absolute risk of HIV transmission through condomless sex with suppressed HIV-1 RNA viral load for both anal and vaginal sex. OBJECTIVE: To evaluate the rate of within-couple HIV transmission (heterosexual and men who have sex with men [MSM]) during periods of sex without condoms and when the HIV-positive p…
Modelling the Potential Population Impact and Cost-Effectiveness of Self-Testing for HIV
HIV testing uptake has increased dramatically in recent years in resource limited settings. Nevertheless, over 50% of the people living with HIV are still unaware of their status. HIV self-testing (HIVST) is a potential new approach to facilitate further uptake of testing which requires consideration, taking into account economic factors. Mathematical models and associated economic analysis can provide useful assistance in decision-making process…
