Professor Jean-Jacques Muyembe-Tamfum has spent more than half a century at the intersection of scientific discovery and outbreak response in Africa. The Congolese virologist helped shape how the world understands and reacts to emerging infectious diseases. Beyond his contributions to Ebola research, his career reflects a broader commitment to building scientific institutions, expertise, and partnerships that enable African countries to respond to health threats on their own terms.
From discovery to treatment
Muyembe was born in 1942 in the Democratic Republic of the Congo. He initially studied medicine at the University of Lovanium, now the University of Kinshasa, where a lab sparked an interest in infectious diseases like typhoid fever and diphtheria. He graduated in 1969 and completed a PhD in virology in Belgium in 1973.
Early research in DRC faced serious limitations. Laboratory infrastructure and equipment were scarce, so he adapted by becoming a field epidemiologist. In 1974, he investigated a cholera outbreak in Matadi, followed by a meningitis outbreak among soldiers in 1975. These experiences prepared him for the assignment that would define his place in global health history.
In 1976, Muyembe was sent to Yambuku to investigate a mysterious illness causing severe disease and deaths. He collected blood samples and sent them to the Institute of Tropical Medicine in Antwerp. There, scientists including Peter Piot and Guido van der Groen isolated the previously unknown virus. Further investigations in the United Kingdom and the United States confirmed it as a new virus, later named Ebola.
At the time, no diagnostic tests, vaccines, or treatments existed. Investigators relied on basic infection prevention and careful observation. Muyembe noted that understanding transmission allowed the team to break the chain. He believes effective response requires engaging communities and adapting interventions to local realities, a lesson reinforced during the 1995 Ebola outbreak in Kikwit.
His team also explored blood transfusions from survivors, a line of research that eventually informed the development of mAb114, a monoclonal antibody treatment derived from a survivor of the Kikwit outbreak. In 2026, five decades after the first recognized outbreak, Muyembe and Piot received the Virchow Prize for their contributions to Ebola research and epidemic preparedness.
Building local capacity
Muyembe has led the National Institute of Biomedical Research (INRB) as Director General since 1998. The institute, established in 1984, has grown into a major center for biomedical research, disease surveillance, diagnostics, and training in the DRC.
He illustrated progress in local diagnostic capacity by recalling that before 2008, DRC had to send Ebola samples to the CDC in Atlanta and wait two weeks for results. Now, the institute performs PCR, ELISA tests, and metagenomic sequencing locally. The scientific workforce has also expanded; when he started as director, he was the only PhD, but today there are fifty.
He stresses that retaining skilled researchers requires sustained investment in working conditions. “We must build good infrastructure and improve salaries and working conditions to prevent a brain drain of researchers leaving for better opportunities abroad,” he said.
His training strategy balances field experience with advanced scientific training. Scientists must first go into the field to learn how to investigate outbreaks in difficult conditions. After two or three years, they travel to leading institutions in Japan, Europe, or the United States. They return with a combination of on-the-ground experience and advanced knowledge, which he believes is essential for strengthening pandemic preparedness.
Global implications
Muyembe challenged the idea that diseases are distant until they cross borders. He noted that the 2022 mpox outbreak in Europe showed that infectious threats are shared. He said, “The world is a village; what happens in Kinshasa or Ibadan can also happen in Brussels or Paris.” This perspective highlights that health security is interconnected.
