Top Ten Best Medical Doctors In South Africa (2025)
10. Professor Koleka Mlisana
Professor Koleka Mlisana leads one of South Africa’s most important public health laboratories and has moved from academic medical microbiology into senior leadership at the National Health Laboratory Service. Her career links practical diagnostics with national policy and she has been central to work on tuberculosis diagnostics, antimicrobial resistance and sexually transmitted infections. By steering laboratory networks and quality systems she helps hospitals and provincial services make diagnoses faster and safer, particularly where laboratory capacity determines whether patients get the right medicines quickly.
Her publications and academic roles also inform training for younger clinical microbiologists and lab scientists across the country. That combination of technical excellence and systems level leadership makes her a trusted figure for clinicians who rely on rapid, accurate test results and for policymakers who must translate science into accessible services.
9. Professor Francois Venter
Professor Francois Venter is a clinician researcher who has been a steady voice in South Africa’s HIV response for decades. He heads Ezintsha, a Wits based research unit that focuses on practical solutions to HIV treatment scale up and prevention. His writing and public commentary often push for strong implementation of testing and treatment programmes that reach rural and urban communities alike.
He is known for combining clinical insight with programmatic thinking so that scientific advances translate into better patient access. That emphasis on implementation makes him a go to expert for hospitals, nongovernmental programmes and funders looking for interventions that will work at scale. His work helps keep treatment programmes resilient and evidence based as new prevention and treatment options emerge.
8. Professor Marietjie Venter
Professor Marietjie Venter is a leading virologist who has built research programmes focused on zoonotic and emerging viral threats. Her work spans viral surveillance, One Health approaches and building laboratory networks for rapid detection of new pathogens.
In a world where identifying a virus early can change the course of an outbreak, her teams’ genomic and field work have strengthened South Africa’s ability to spot and characterise viral threats quickly. She also contributes to international advisory groups and training programmes that bring global standards into local practice. For provinces and research consortia seeking expertise in virus detection, surveillance and public health response, her lab and her leadership are core assets.
7. Professor Tulio de Oliveira
Professor Tulio de Oliveira is a genomics and infectious disease scientist who helped build one of Africa’s most advanced pathogen sequencing centres. His teams were instrumental in identifying important SARS CoV 2 variants and in expanding genomic surveillance capacity across the continent. That work has not only informed immediate pandemic response but also left a lasting infrastructure used for tuberculosis, HIV and other infectious disease research. His focus on rapid sequencing, data sharing and local training has made South Africa a regional hub for genomic epidemiology and for partners seeking technical collaborations on surveillance, vaccine response and outbreak investigation.
6. Professor Glenda Gray
Professor Glenda Gray is a paediatrician and a senior research leader who has spent her career on child health and HIV related research. As a former head of South Africa’s medical research council and a founder of major perinatal research units, she has shaped national policy on maternal and child health and on clinical trials. Her clinical and research experience sits at the interface of bedside care and large scale studies, so the evidence generated by her teams has guided vaccine policies and maternal health interventions. Health institutions consult her for direction on ethical clinical trial conduct as well as for pragmatic research that improves services for mothers and children.
5. Professor Shabir Madhi
Professor Shabir Madhi is a leading vaccinologist and paediatrician whose work has underpinned vaccine policy for children and pregnant women. He directs major vaccine research units at a top university and has led trials that informed global recommendations for pneumococcal and rotavirus vaccines. During the recent pandemic his leadership in vaccine trials and in building clinical trial networks strengthened local capacity to run large scale studies under real world conditions. That experience continues to attract collaborations for new vaccine candidates and implementation research that directly benefits South African patients and health services.
4. Professor Helen Rees
Professor Helen Rees has been a cornerstone of public health practice in South Africa for many years. Her leadership in vaccinology, sexual and reproductive health and pandemic preparedness has combined academic rigour with long term policy advising for the national department of health. She leads and advises institutions working on vaccine deployment and health system readiness and her work has influenced public health decision making across the region. Hospitals, health agencies and international partners draw on her experience when planning vaccination campaigns and preparing for health emergencies.
3 — Professor Dan J Stein
Professor Dan J Stein is one of South Africa’s most cited mental health researchers and a senior academic clinician in psychiatry. His work spans clinical practice, neuroscience research and the development of mental health services adapted for low and middle income settings. He helped to build national research capacity in psychiatry and has been involved in large collaborative projects across several African countries. Clinicians and medical schools look to his publications and training programmes when developing services that integrate mental health care into general practice, which in turn broadens access for patients who historically had poor access to specialist care.
2 — Professor Linda Gail Bekker
Professor Linda Gail Bekker is a physician scientist and an influential leader in HIV and TB research. She directs the Desmond Tutu HIV Centre and leads work on prevention, adolescent health and large scale clinical trials. Her teams translate research into community facing programmes that improve access to testing, prevention and treatment for the most vulnerable populations. She has also played a leading role in major multicentre trials and in shaping how new prevention tools are rolled out across clinics. For organisations looking to reach young people with pragmatic, evidence based HIV services, her centre is a primary partner.
1. Professor Salim S Abdool Karim
Professor Salim Abdool Karim is widely recognised for decades of leadership in infectious disease epidemiology. His research on HIV prevention and treatment helped position South Africa at the forefront of epidemic science and his public health advice has guided national responses to major outbreaks. He has served on global advisory bodies and continues to contribute to policy and research that affect patient care, public health planning and international collaborations. That combination of rigorous epidemiology, practical policy advice and mentoring of younger researchers is why many clinicians and health leaders look to his work when designing prevention programmes and research platforms.
