  • Managing the move

    Maria F Nardell, Joo-Mi Lee et al.ARTICLEAIDS Care2026

    Men in South Africa are disproportionately underrepresented in HIV care, and men who migrate face challenges using HIV services. Positive coping skills are critical for effective healthcare decision-making, yet little is known how men’s HIV status and mobility-related stressors affect their coping strategies. Johannesburg is home to ∼5 million people who have relocated from elsewhere, mostly men. From February-April 2024, we conducted a cross-sec…

  • Understanding HIV Vaccine Misinformation and Vaccine Intentions Among Young Women in South Africa

    Open AccessBrendan Maughan-Brown, Teniola I Egbe et al.ARTICLEAIDS and Behavior2026

    An effective HIV vaccine could significantly reduce HIV incidence, but demand for future HIV vaccines will be affected by misinformation. We conducted an online survey (March-April 2024) to identify the misinformation claims most likely to deter young women in South Africa (n = 188) from receiving an HIV vaccine. Participants rated HIV-vaccine misinformation as most concerning (i.e. would make them not want to get vaccinated) and least concerning…

  • Using sputum and tongue swab specimens for in-home point-of-care targeted universal testing for tuberculosis of household contacts

    Open AccessCharl Bezuidenhout, Lawrence Long et al.ARTICLEBMJ Global Health2025

    INTRODUCTION: Effective strategies are essential for early tuberculosis (TB) detection. Reliance on passive case detection, symptom screening and collection of sputum results in delayed or undiagnosed TB, contributing to on-going TB transmission. This study assessed the acceptability of in-home targeted universal TB testing (TUTT) using GeneXpert MTB/RIF Ultra at point-of-care (POC) during household contact investigations (HCIs) and the feasibili…

  • Behaviourally-Informed Two-Way Text Messaging to Improve Return to HIV Care in South Africa

    Open AccessChristine Njuguna, Preethi Mistri et al.ARTICLEAIDS and Behavior2025

    One-way text messaging to re-engage people in HIV care has shown promise, but little is known about two-way messaging. We evaluated a behaviourally-informed two-way text messaging intervention to increase re-engagement in care following missed visits. We conducted an individual-level randomised controlled trial between February and March 2023 in Capricorn District, South Africa. Adults aged ≥ 18 years who had missed an ART visit by > 28 days were…

  • HIV Care for Men on the Move

    Open AccessMaria F Nardell, Caroline Govathson et al.ARTICLEAIDS and Behavior2025

  • Applying behavioural economics principles to increase demand for free HIV testing services at private doctor-led clinics in Johannesburg, South Africa

    Open AccessSimamkele Bokolo, Suzanne Mabaso et al.ARTICLEPLOS Global Public Health2024

    Expanding free HIV testing service (HTS) access to include private clinics could increase testing rates. A donor funded programme, GP Care Cell, offered free HIV testing at selected private doctor-led clinics but uptake was low. We investigated whether HTS demand creation materials that used behavioural economics principles could increase demand for HIV testing at these clinics. We conducted a randomised controlled trial in Johannesburg, South Af…

  • Migrant men and HIV care engagement in Johannesburg, South Africa

    Open AccessMaria F Nardell, Caroline Govathson et al.ARTICLEBMC Public Health2024

    Our study revealed a high proportion of migrants within our community-based sample of men and demonstrated a need for HIV and other healthcare services that effectively reach migrants in Johannesburg. Future research is warranted to further disaggregate this heterogenous population by different dimensions of mobility and to understand how to design HIV programs in ways that will address migrants' challenges

  • Quasi-experimental evaluation of a financial incentive for first-dose Covid-19 vaccination among adults aged ≥60 years in South Africa

    Open AccessCandice Chetty-Makkan, Harsha Thirumurthy et al.ARTICLEBMJ Global Health2022

    INTRODUCTION: COVID-19 vaccination coverage in South Africa (RSA) remains low despite increased access to vaccines. On 1 November 2021, RSA introduced the Vooma Voucher programme which provided a small guaranteed financial incentive, a Vooma Voucher redeemable at grocery stores, for COVID-19 vaccination among older adults, a population most vulnerable to serious illness, hospitalisation and death. However, the association of financial incentives …

  • Reduction in initiations of drug-sensitive tuberculosis treatment in South Africa during the Covid-19 pandemic

    Open AccessMariet Benade, Lawrence Long et al.ARTICLEPLOS Global Public Health2022

    In response to the global pandemic of COVID-19, South Africa implemented a strict lockdown in March 2020 before its first COVID-19 wave started, gradually lifted restrictions between May and September 2020, and then re-imposed restrictions in December 2020 in response to its second wave. There is concern that COVID-19-related morbidity and mortality, the deprioritization of TB activities, fear of transmission, and societal restrictions led to a r…

  • The early-stage comprehensive costs of routine PrEP implementation and scale-up in Zambia

    Open AccessCheryl Hendrickson, Lawrence Long et al.ARTICLEPLOS Global Public Health2022

    Pre-exposure prophylaxis (PrEP) is an effective HIV prevention option, but cost-effectiveness is sensitive to implementation and program costs. Studies indicate that, in addition to direct delivery cost, PrEP provision requires substantial demand creation and client support to encourage PrEP initiation and persistence. We estimated the cost of providing PrEP in Zambia through different PrEP delivery models. Taking a guidelines-based approach for …

  • Primary healthcare seeking behaviour of low-income patients across the public and private health sectors in South Africa

    Open AccessK Govender, Sarah Girdwood et al.ARTICLEBMC Public Health2021

    It is imperative to understand the potential impact on where PHC services are accessed once affordability is mitigated through the NHI as this has implications on planning and contracting of services under the NHI

  • “Even if you’re HIV-positive there’s life after if you take your medication”

    Cheryl Hendrickson, Aneesa Moolla et al.ARTICLEAIDS Care2019

    South Africa's national antiretroviral treatment (ART) programme, initiated in 2004, is the largest HIV treatment programme in the world with an estimated 4.2 million people on ART. Today, an HIV diagnosis is no longer associated with certain death, but is rather a manageable chronic disease, with all HIV-positive patients now eligible to receive treatment. In this study, we explore patient experiences at the onset of the ART programme, including…

  • Effective public-private partnerships for sustainable antiretroviral therapy

    Open AccessIdah Mokhele, Sello Mashamaite et al.ARTICLEBMC Public Health2019

    Our results show that private-GPs can contribute to caring for stabilized public sector HIV patients on life-long ART. However, they require special efforts to improve retention in care

  • Treatment outcomes among children, adolescents, and adults on treatment for tuberculosis in two metropolitan municipalities in Gauteng Province, South Africa

    Open AccessKaitlyn M Berry, Carly A Rodriguez et al.ARTICLEBMC Public Health2019

    Young adults in urban areas of Gauteng Province experience a disproportionate burden of LTFU and low coverage of ART among co-infected patients. This group should be targeted for interventions aimed at improving clinical outcomes and retention in both TB and HIV care

  • Data quality of drug-resistant tuberculosis and antiretroviral therapy electronic registers in South Africa

    Open AccessLise Jamieson, Denise Evans et al.ARTICLEBMC Public Health2019

    The underreporting of death and the lack of ART or TB status in the electronic DR-TB and ART registers could negatively impact monitoring efforts by downplaying the state of the TB/HIV epidemic. Improved recording of these data sources, and data integration across systems, could improve the accuracy of reporting for the national HIV/ART and TB programs

  • Dietary intake among paediatric HIV-positive patients initiating antiretroviral therapy in Johannesburg, South Africa

    Open AccessNozipho Musakwa, Alison Feeley et al.ARTICLEVulnerable Children and Youth…2019References: 1

    In South Africa, prevention of mother to child transmission (PMTCT) has reduced MTCT from 3.6% in 2011 to 1.3% in 2017. However, there are challenges in reaching vulnerable HIV-positive children; those at increased risk of malnutrition or present late with advanced disease. Macro – and micronutrient deficiencies, common in HIV, may accelerate disease progression. This was a prospective cohort study of paediatric patients (aged 1–10 years) initiat…

  • Acceptability and feasibility of a financial incentive intervention to improve retention in HIV care among pregnant women in Johannesburg, South Africa

    Kate Clouse, Constance Mongwenyana et al.ARTICLEAIDS Care2018

    Women initiating antiretroviral therapy during pregnancy are at high risk of dropping out of HIV care after delivery. We assessed the acceptability and feasibility of a financial incentive - a one-time R50 (∼USD4) supermarket voucher for completing one postpartum visit ≤10 weeks of delivery - to improve postpartum retention. We enrolled 100 pregnant, HIV-positive women at a primary health clinic in Johannesburg, South Africa. Participants were in…

  • Retention in care, resource utilization, and costs for adults receiving antiretroviral therapy in Zambia

    Open AccessCallie A Scott, Hari S Iyer et al.ARTICLEBMC Public Health2014

    Patients initiate ART late in the course of disease progression and a large proportion drop out of care after initiation. The quantity of resources utilized and costs vary widely by site, and patients utilize a different mix of resources under routine clinical conditions than if they were receiving fully guideline-concordant care. Improving retention in care and guideline concordance, including increasing the use of tenofovir in first-line ART re…
