Infectious Disease Specialist

You are the expert in infections – from HIV and TB to malaria, Ebola, and the next pandemic.

What this life looks like

More people in Africa die from infections than from any other cause – and as an Infectious Disease Specialist you dedicate your medical career to diagnosing, treating, and preventing infectious diseases. You are the consultant other doctors call when a patient has a fever of unknown origin, a complex HIV infection, drug-resistant tuberculosis, a tropical disease the general physician has never seen before, or a potential outbreak that needs rapid identification and containment. Infectious disease is one of the most intellectually stimulating specialties in medicine – it requires broad knowledge across microbiology, pharmacology, immunology, and clinical medicine. In Africa it is also one of the most critical. HIV and tuberculosis together kill more than a million Africans every year. Malaria kills hundreds of thousands annually. Meningitis, typhoid, cholera, viral haemorrhagic fevers, and emerging infections including COVID-19 all require specialist expertise for effective management and outbreak response. The infectious disease specialist in Africa is at the frontier of some of the most important medical work in the world.

What she actually does

An Infectious Disease Specialist diagnoses and treats complex infections in hospitalised and outpatient patients, manages HIV care including antiretroviral therapy and the treatment of opportunistic infections, manages drug-resistant tuberculosis, consults on fever of unknown origin, tropical disease presentations, and immunocompromised patients with infections, advises on infection prevention and control in hospitals, contributes to outbreak investigation, and participates in antimicrobial stewardship programmes to reduce inappropriate antibiotic use.

Why it matters in Africa

Africa carries the majority of the global burden of HIV, tuberculosis, and malaria simultaneously. Drug-resistant infections – resistant TB, resistant malaria, resistant bacterial infections – are growing threats that require highly trained specialist management. The risk of emerging infectious diseases including viral haemorrhagic fevers is concentrated in Africa. Antimicrobial resistance, if not managed, threatens to make common bacterial infections untreatable. Infectious disease specialists are essential to all of these challenges.

Your pathway in

Biology, Chemistry, and Mathematics at secondary school. Then MBBS or MBChB over five to six years, followed by housemanship. Internal medicine residency then subspecialty fellowship in infectious diseases and tropical medicine through the West African College of Physicians or equivalent body follows. Some African infectious disease physicians also train in clinical microbiology or tropical medicine. The full pathway takes approximately 12 to 14 years.

Skills you will need

Technical: Microbiological diagnosis, management of HIV and TB including drug-resistant variants, tropical disease diagnosis and treatment, antimicrobial stewardship, infection control, and fever workup. Human: Broad medical knowledge spanning multiple organ systems – infections affect the whole body – systematic thinking for complex diagnostic challenges, and the ability to manage patients with stigmatised conditions like HIV with compassion and without judgment. Digital tools: Microbiology laboratory information systems, HIV and TB patient management databases, infection surveillance systems, and antimicrobial stewardship software.

A woman in this field

Dr. Francine Ntoumi

Republic of Congo

Dr. Ntoumi is a premier molecular biologist and a leader in the fight against malaria. She is the founder and Director General of the Fondation Congolaise pour la Recherche Médicale (FCRM). She has been instrumental in developing health research capacity in Central Africa and was the first African woman to be awarded the Christophe Mérieux Prize. Her work focuses on the molecular epidemiology of malaria and advocating for the increased participation of African scientists in international clinical trials.

Take your first step

Biology and Chemistry are your essential subjects at school. Start by learning about the three diseases that dominate infectious disease practice in Africa – HIV, tuberculosis, and malaria. UNAIDS, the Stop TB Partnership, and the WHO malaria report all publish freely accessible annual data and analyses. If you can access any research papers on African infectious disease – search Google Scholar for free articles – start reading them. The ability to engage with scientific literature is a skill that begins in secondary school and compounds throughout your career.
