Wits RHI is a research and implementation Institute that is dynamic, progressive, and responsive to global and local health emergencies. We pioneer cutting-edge science and innovation in the fields of infectious and vaccine preventable diseases; maternal and family health; antimicrobial resistance, climate change and emerging crises.
Our strength lies in our multi-disciplinary and holistic approach to improving health outcomes at a local and global level through research, technical assistance, advocacy, policy development, implementation science and health systems strengthening. We identify health problems through sound epidemiological methods and qualitative research, and use a range of analytic and research methods to generate evidence and test and evaluate interventions in a real word setting.
We are a part of the Faculty of Health Sciences at the University of the Witwatersrand, a world class African University, and its largest Institute.
We are a Joint United Nations Programme on AIDS (UNAIDS) and South African Medical Research Council (SAMRC) collaborating centre and a strategic partner to the United Nations Population Fund (UNFPA).
Our work is focused on populations that are most in need, marginalised, or hard to reach. These include:
Abstract
There has been significant progress in the rollout of oral pre-exposure prophylaxis (PrEP) for the prevention of HIV. The introduction of long-acting prevention methods holds the potential to improve HIV prevention uptake and use, however, presents unique complexities regarding HIV diagnosis and potential for resistance. Quantifying and understanding the scenarios within which seroconversions occur may help to inform approaches to identifying acute HIV in programmes delivering PrEP at scale.
