  • Population-level viremia predicts HIV incidence at the community level across the Universal Testing and Treatment Trials in eastern and southern Africa

    Open AccessJoseph Larmarange, Pamela Bachanas et al.ARTICLEPLOS Global Public Health2023

    Universal HIV testing and treatment (UTT) strategies aim to optimize population-level benefits of antiretroviral treatment. Between 2012 and 2018, four large community randomized trials were conducted in eastern and southern Africa. While their results were broadly consistent showing decreased population-level viremia reduces HIV incidence, it remains unclear how much HIV incidence can be reduced by increasing suppression among people living with…

  • The Impact of Drought on HIV Care in Rural South Africa

    Open AccessCollins Iwuji, Collins C Iwuji et al.ARTICLEEcoHealth2023

    This analysis investigates the relationship between drought and antiretroviral treatment (ART) adherence and retention in HIV care in the Hlabisa sub-district, KwaZulu-Natal, South Africa. Data on drought and ART adherence and retention were collated for the study period 2010–2019. Drought was quantified using the 3-month Standard Precipitation Evapotranspiration Index (SPEI) and Standard Precipitation Index (SPI) from station data. Adherence, pr…

  • Investigation of post-trial access views among study participants and stakeholders using photovoice and semistructured interviews

    Open AccessNothando Ngwenya, Collins Iwuji et al.ARTICLEJournal of Medical Ethics2022

    PURPOSE: We examine the levels of post-trial responsibility ascribed to different stakeholders, following a community-based clinical trial and how the 'responsibility' is understood. METHODS: We employed photovoice, unstructured observations and key informant interviews to gain insights into contexts of access to care following transition to the public health system post trial. We used an inductive narrative analysis to explore experiences and un…

  • Costs and economies of scale in repeated home-based HIV counselling and testing

    Open AccessMarwân-Al-Qays Bousmah, Collins Iwuji et al.ARTICLESocial Science & Medicine2022Referencias: 29

    Universal HIV testing is now recommended in generalised HIV epidemic settings. Although home-based HIV counselling and testing (HB-HCT) has been shown to be effective in achieving high levels of HIV status awareness, little is still known about the cost implications of universal and repeated HB-HCT. We estimated the costs of repeated HB-HCT and the scale economies that can be obtained when increasing the population coverage of the intervention. W…

  • Institutional Responses to Drought in a High HIV Prevalence Setting in Rural South Africa

    Open AccessKingsley Stephen Orievulu, Collins IwujiARTICLEInternational Journal of…2021

    In 2015, South Africa experienced one of the worst (El Niño-induced) droughts in 35 years. This affected economic activities, individual and community livelihoods and wellbeing especially in rural communities in northern KwaZulu-Natal. Drought's direct and indirect impacts on public health require urgent institutional responses, especially in South Africa's stride to eliminate HIV as a public health threat by 2030 in line with the UNAIDS goals. T…

  • Early ART Initiation Improves HIV Status Disclosure and Social Support in People Living with HIV, Linked to Care Within a Universal Test and Treat Program in Rural South Africa (ANRS 12249 TasP Trial)

  • Factors associated with antiretroviral treatment initiation amongst HIV-positive individuals linked to care within a universal test and treat programme

    Open AccessSimon Boyer, Collins Iwuji et al.ARTICLEAIDS Care2016

    Prompt uptake of antiretroviral treatment (ART) is essential to ensure the success of universal test and treat (UTT) strategies to prevent HIV transmission in high-prevalence settings. We describe ART initiation rates and associated factors within an ongoing UTT cluster-randomized trial in rural South Africa. HIV-positive individuals were offered immediate ART in the intervention arm vs. national guidelines recommended initiation (CD4≤350 cells/m…

  • Community perceptions of repeat HIV-testing

    Open AccessJoanna Orne-Gliemann, Thembelihle Zuma et al.ARTICLEAIDS Care2016

    In the context of the ANRS 12249 Treatment as Prevention (TasP) trial, we investigated perceptions of regular and repeat HIV-testing in rural KwaZulu-Natal (South Africa), an area of very high HIV prevalence and incidence. We conducted two qualitative studies, before (2010) and during the early implementation stages of the trial (2013-2014), to appreciate the evolution in community perceptions of repeat HIV-testing over this period of rapid chang…

  • “It is better to die”

    Open AccessMosa Moshabela, Thembelihle Zuma et al.ARTICLEAIDS Care2016

    The ANRS 12249 Treatment-as-Prevention (TasP) cluster-randomized trial in rural South Africa uses a "test and treat" approach. Home-based testing services and antiretroviral treatment initiation satellite clinics were implemented in every cluster as part of the trial. A social science research agenda was nested within TasP with the aim of understanding the social, economic and contextual factors that affect individuals, households, communities an…

  • Addressing social issues in a universal HIV test and treat intervention trial (ANRS 12249 TasP) in South Africa

  • Older HIV-infected individuals present late and have a higher mortality

    Open AccessCollins Iwuji, Collins C Iwuji et al.ARTICLEBMC Public Health2013

    Older adults were more likely to present late and had a higher mortality. Initiatives to expand HIV testing in clinical and community setting should not neglect individuals aged over 50
