The Great Health Worker Exodus: Why Africa Keeps Losing the Doctors and Nurses It Trains
Africa is training more health workers than at any point in its history.
Medical school enrollment is climbing, nursing programs are multiplying, and by nearly every measure the continent's health workforce pipeline is fuller than it was a decade ago. And yet walk into a public hospital in Lagos, Accra, Harare, Lusaka, or Kampala and you're still likely to find wards stretched thin, understaffed night shifts, and patients waiting far longer than they should for a nurse or doctor to reach them.
That contradiction — more graduates, fewer hands on deck — is the story of Africa's health worker exodus. It isn't a training failure. It's a retention failure. Every year, tens of thousands of the continent's most qualified doctors, nurses, and midwives pack up for London, Toronto, Riyadh, or Berlin, chasing salaries, working conditions, and career paths their home systems can't yet offer.
The WHO's State of the Health Workforce in Africa 2026 report puts the underlying tension plainly: the region's workforce is growing, but unemployment, poor distribution, and migration are eating into that progress faster than training programs can outpace them. Africa's problem in 2026 isn't producing health workers. It's keeping them.
This isn't a Nigeria story, or a Ghana story, or a Zimbabwe story, even though those three countries dominate the headlines. It's a continental pattern that now touches nearly every health system in Sub-Saharan Africa and North Africa alike, from long-established migration corridors in West Africa to newer, faster-growing ones in East and Southern Africa.
A Workforce That's Growing — and Still Falling Behind
Between 2018 and 2024, the WHO African Region saw its number of doctors grow by roughly 26–27%, nurses by about 31%, and midwives by a striking 81%. On paper, that's exactly the kind of expansion the continent needs.
But population growth and rising healthcare demand are outpacing it. WHO estimated the region's needs-based shortage at around 5.6 million workers in 2022, a gap it projects could widen to 6.1 million by 2030 without a serious acceleration in training and — critically — retention.
The math only makes sense once you see that Africa's crisis has four separate ingredients tangled together: shortage, unemployment, maldistribution, and migration. A country can be short-staffed in its rural clinics while simultaneously having newly qualified nurses who can't find a paying job, and losing its most experienced specialists to a hospital in Manchester — all at the same time. None of those problems cancels the others out. They compound.
Layered on top of all this is a demographic squeeze happening in the destination countries themselves. The UK, Germany, Canada, Australia, and much of Western Europe have aging populations and aging health workforces of their own. Their demand for imported labor isn't a temporary post-pandemic blip — it's structural, and it's not going away. That means the pull factor drawing African health workers abroad is likely to remain strong for decades, regardless of what individual visa policies do in any given year.
Following the Money — and the Visa Rules
There's no single country African health workers are migrating to; the routes differ by language, colonial history, licensing systems, and plain economic opportunity.
The United Kingdom built the clearest recent case study in how fast a migration corridor can open — and how quickly it can be throttled by policy. After the UK's Health and Care Worker visa launched and international recruitment surged post-pandemic, applications peaked at 145,823 in the year ending December 2023, with Nigerian, Ghanaian, and Zimbabwean nationals forming a major share. Then the UK tightened its immigration rules, and the pipeline nearly collapsed: nursing visas under that route fell 73% to just 1,777 by the year ending December 2025. The workforce that arrived during the boom largely stayed, though — the UK's Nursing and Midwifery Council recorded Nigeria as the second-largest source of newly registered international nurses and midwives in 2025–26 (1,614 joiners), with Ghana third (1,391).
The United States remains the largest single market for foreign-trained doctors and nurses in the world, though its licensing exams and state-by-state credentialing make the path slower than in the UK or Gulf states. Together with the UK and Germany, the US absorbs 58% of all foreign-trained doctors and 61% of foreign-trained nurses working across OECD countries. Nigeria alone supplied an estimated 17,060 doctors and 54,480 nurses to OECD countries as of 2020–21 — making it the fourth-largest source of migrant nurses in the entire OECD.
Canada sells something the others don't always offer as cleanly: a path to permanent residency, not just a work contract. For a mid-career nurse or doctor weighing options, that changes the calculation from "where can I earn more" to "where can I actually settle and raise a family long-term."
Australia and New Zealand compete on quality of life and chronic shortages outside their major cities, drawing steadily from the same pool, with South African-trained doctors and nurses forming a particularly large and long-established presence in both countries.
Germany and France round out the European picture, with France carrying particular weight for Francophone Africa — doctors born in African countries make up 49.4% of all migrant doctors practicing in France, a legacy of colonial-era language and education ties that still shapes migration decades later. Belgium plays a similar, smaller role for health workers from the Democratic Republic of Congo, Rwanda, and Burundi, where French remains the language of medical training.
The Gulf states — Saudi Arabia, the UAE, Qatar, Kuwait, Bahrain, Oman — round out the map with a different pitch entirely: tax-free salaries, modern hospitals, and international experience without necessarily committing to permanent emigration. Foreign-born workers make up 50% or more of the healthcare workforce in several Gulf countries, making the region one of the most internationalized health labor markets anywhere. For health workers from Sudan, Egypt, and East Africa in particular, the Gulf is often a closer and culturally more familiar first stop than Europe or North America.
It's also worth noting that migration isn't only an Africa-to-the-West story. There is a significant, less-discussed pattern of intra-African migration, where health workers from lower-income countries move to relatively better-resourced regional hubs. South Africa, Botswana, Namibia, and Kenya have all, at different points, drawn doctors and nurses from neighboring countries — meaning some African nations are simultaneously losing workers to Europe and the Gulf while gaining workers from their immediate neighbors. That dynamic complicates any simple story of Africa as a single, uniform "source" region.
Country Snapshots: A Continent-Wide Pattern
Nigeria
Nigeria anchors the entire debate. Nigerian-trained doctors and nurses appear near the top of nearly every OECD migration list. A 2025 UK government report, citing Nigerian figures, put the country's registered doctors at roughly 85,000–90,000 — with only about 55,000 estimated to still be practicing inside Nigeria as of 2024. The gap between those two numbers is the entire brain drain debate in miniature. The phenomenon is common enough in Nigeria to have its own slang term, "japa," used broadly to describe skilled professionals — not just health workers — leaving the country for better opportunities abroad.
Ghana
Ghana shows how contradictory the crisis can look up close. Health worker density more than doubled over two decades (from 16.56 to 41.92 per 10,000 people), yet WHO recorded over 3,000 Ghanaian nurses and midwives migrating in 2022 alone, mostly to the UK, US, Ireland, and Canada — even as some newly qualified nurses at home struggled to find employment. Ghana's Ministry of Health has periodically introduced bonding schemes requiring newly trained doctors to work domestically for a set number of years before being cleared to emigrate, an approach with mixed and contested results.
Zimbabwe
Zimbabwe may be the starkest case on the continent. In 2021, 2,080 Zimbabwean nurses requested the verification letters typically needed to register or work abroad. WHO estimates roughly one in five Zimbabwean-trained doctors and nurses is now employed by the UK's National Health Service. In the OECD's rankings of nurse-origin countries, Zimbabwe jumped from 38th place in 2000–01 to 11th around 2020–21 — one of the fastest climbs on record. Zimbabwe's economic instability over the past two decades has made the pull of stable overseas salaries especially powerful, and the country now has generations of nursing families with relatives already established in the UK, further reinforcing the pipeline.
Kenya
Kenya has climbed steadily as a nurse-origin country, rising from 45th to 20th in the OECD's rankings between 2000–01 and around 2020–21. Kenya has also become a notable exporter of health workers to the Gulf states, alongside its more traditional migration ties to the UK. At the same time, Kenya functions as a regional training hub, with its medical and nursing schools drawing students from across East Africa — meaning it plays a dual role as both a significant source of outward migration and a producer of health workers who go on to serve elsewhere on the continent.
Cameroon
Cameroon posted one of the largest jumps in nurse emigration rate of any country the OECD tracked, up 53 percentage points over the period analyzed. As a bilingual country with both Anglophone and Francophone health training systems, Cameroon has migration pathways open to it that many single-language countries don't — its nurses and doctors can plausibly target the UK, Canada, and the US on one side, and France, Belgium, and Switzerland on the other.
South Africa
South Africa occupies a uniquely complicated position in this story. It is simultaneously one of the continent's most significant sources of emigrating doctors and nurses — with long, well-established migration corridors to the UK, Australia, Canada, and New Zealand dating back decades — and one of the continent's most significant destination countries for health workers from poorer neighboring states, including Zimbabwe, Malawi, and the Democratic Republic of Congo. South Africa's relatively well-resourced private healthcare sector also draws talent away from its own public hospitals internally, creating a domestic version of the same maldistribution problem seen at the continental level. In effect, South Africa both drains and receives — often for the same underlying reasons of pay and working conditions that drive every other country in this story.
Egypt, Morocco, and Tunisia
North Africa's health worker migration has followed a somewhat different track, shaped heavily by proximity to Europe and, for Francophone Morocco and Tunisia, historic ties to France. Egyptian doctors have long featured prominently among migrant physicians in the Gulf states and, increasingly, in the UK and North America. Morocco and Tunisia have seen persistent emigration of doctors and nurses toward France, Belgium, and increasingly Germany, which has stepped up active recruitment across the Maghreb as it works to fill its own workforce gaps. Tunisia in particular has faced repeated public debate over the loss of newly trained specialist doctors, a significant fraction of whom reportedly leave within a few years of completing their residencies.
Ethiopia, Uganda, and Tanzania
East Africa's larger economies — Ethiopia, Uganda, and Tanzania — have all expanded medical and nursing training substantially over the past fifteen years, part of a broader regional push to reduce dependence on foreign-trained staff. But all three continue to see meaningful outflows of qualified professionals, particularly specialists such as anesthesiologists, radiologists, and surgeons, whose skills are in chronically short supply both at home and abroad, making them especially attractive to international recruiters. Uganda, notably, also trains a significant number of health professionals from other African countries at its regional medical schools, adding another layer to the intra-African flows described above.
Zambia and Malawi
Zambia and Malawi illustrate how severe the workforce crunch can get in smaller, lower-income health systems. Both countries have historically had among the lowest doctor-to-population ratios in the world, and both have struggled for years with the same paradox seen in Ghana: newly trained nurses unable to secure public-sector jobs at home even as rural clinics go chronically understaffed. Malawi in particular has drawn international attention for aggressive UK- and Ireland-based nurse recruitment campaigns targeting its graduates, prompting periodic government appeals for more ethical, managed recruitment arrangements.
Sierra Leone and Liberia
Sierra Leone and Liberia, still rebuilding health systems that were severely strained by the 2014–2016 Ebola outbreak and, in Liberia's case, prior civil conflict, have some of the thinnest health workforces on the continent relative to population. Even modest numbers of departing doctors or specialist nurses can have an outsized effect on care availability in these smaller systems, making workforce retention here less a matter of scale than of sheer fragility.
Sudan and the Democratic Republic of Congo
Conflict adds an entirely different migration driver in countries like Sudan and the Democratic Republic of Congo, where displacement, insecurity, and the collapse of parts of the health system push doctors and nurses to leave — sometimes as refugees or asylum seekers rather than through the more orderly visa pathways seen elsewhere on this list. Sudanese doctors have a particularly long-established presence in Gulf states and the UK, a pattern that predates the country's more recent conflict but has likely intensified because of it.
Rwanda
Rwanda stands out as something of a partial counterexample. Following a deliberate, government-led push to rebuild its health system after the 1994 genocide, Rwanda has invested heavily in domestic medical education, task-shifting programs that expand what nurses and community health workers are authorized to do, and performance-based financing for health facilities. While Rwanda is not immune to health worker emigration, its retention outcomes are frequently cited by health policy researchers as relatively stronger than those of several of its regional peers — evidence that deliberate domestic investment can meaningfully shift the retention equation, even without matching Western salary levels.
Why People Actually Leave
It's tempting to file this all under "better pay abroad," and salary is a real driver — a professional who can multiply their income several times over by relocating has an obvious incentive. But narrowing the story to money misses most of what's actually going on.
Salary. International pay can allow health workers to support extended family, buy property, pay down debt, and save for retirement in ways that domestic public-sector salaries across much of the continent simply cannot match. For a nurse supporting siblings' school fees or aging parents, this isn't an abstract calculation — it's often the deciding factor.
Working conditions. Chronic understaffing, unsafe facilities, and equipment shortages wear people down faster than low pay alone ever would. A nurse routinely responsible for two or three times the patient load considered safe elsewhere may eventually decide no salary increase at home is worth the toll.
Career development. Larger foreign hospitals offer specializations — critical care, oncology, cardiology, emergency medicine — that many home systems simply can't support yet, both because of limited equipment and because there may not be enough specialist positions to justify the training pipeline domestically.
Infrastructure. A doctor trained to deliver modern care but working without the equipment to do it experiences a specific, demoralizing kind of professional frustration — knowing exactly what a patient needs and being unable to provide it.
Political and economic stability. Currency instability, inflation, corruption, and general uncertainty about the future all push people toward systems that feel more predictable, independent of the health sector specifically.
Family and networks. Migration is rarely an individual decision. Once a handful of colleagues have successfully relocated, the path becomes easier for everyone who follows — recruitment agencies, diaspora communities, and word-of-mouth all lower the barrier to the next person's move. The UK's Migration Observatory found that Indian, Nigerian, and Zimbabwean nationals together accounted for nearly 63% of admissions under the UK's Health and Care visa route between 2021 and 2024 — a sign of exactly how self-reinforcing these corridors become once established. A prospective migrant nurse in Harare today doesn't need to figure out the UK registration process from scratch; a former classmate who did it three years ago can walk them through it directly.
Is This Actually Bad? It's Complicated.
"Brain drain" is a loaded phrase, and it flattens a situation that has real winners at multiple levels. The individual professional often benefits enormously — better pay, better training, a better life for their family. The destination country fills a workforce gap it may not be able to solve domestically. And the source country isn't left with nothing: remittances flow back, diaspora professionals mentor and fund projects from abroad, and some migrants eventually return with new skills and capital.
But those benefits sit at different levels of the system, and they don't cancel out the loss. A family in Kumasi might be receiving steady remittances from a daughter nursing in Leeds while the local district hospital operates with half the nursing staff it needs. Both things are true simultaneously. Money sent home doesn't automatically become staffing at a rural clinic.
There's also a harder economic question underneath all of this: who actually pays for the world's healthcare workforce? Training a doctor costs years of public investment — university funding, clinical infrastructure, teaching hospitals, subsidized tuition. When that doctor emigrates permanently, the country that receives them inherits a fully trained professional without having borne much of the cost of producing them. It's a real transfer of value from poorer health systems to richer ones, even when every individual choice along the way was completely legitimate.
WHO has tried to formalize some guardrails around this through its Global Code of Practice on the International Recruitment of Health Personnel, along with a Health Workforce Support and Safeguards List that flags countries facing the most severe shortages, discouraging active recruitment from them without compensating measures. The scale involved is enormous: the OECD estimates roughly 89,000 doctors and 257,000 nurses currently working in OECD countries originated from safeguards-list countries, with Nigeria the largest African source of doctors and Nigeria, Ghana, Zimbabwe, and Cameroon among the top African sources of nurses. Several of the smaller countries discussed above — including Sierra Leone, Liberia, Malawi, and Zambia — also appear on or near that safeguards list, meaning international recruiters are, in principle, supposed to exercise particular caution when hiring from them.
The Remittance Effect — and Its Limits
One of the most frequently cited benefits of migration is money sent home. African health workers living overseas send meaningful sums to relatives, supporting housing, education, healthcare costs, small businesses, and everyday household expenses. For individual families, this can be genuinely transformative — funding a home renovation, covering a sibling's university fees, or providing a financial cushion that simply wasn't available before.
But remittances flow to households, not to health systems. A family may be considerably better off financially while their local hospital becomes increasingly understaffed. This is one reason brain drain resists being reduced to a simple economic calculation: the benefits and the costs occur at entirely different levels of society.
The individual professional may gain. The family may gain. The destination country may gain. The source health system may lose. All four of those statements can be true in the same country, about the same person, at the same time. The policy challenge is finding ways to grow the gains without letting the losses become unsustainable for the health system left behind.
The Part That Gets Overlooked: Unemployed Workers, Understaffed Wards
One of the strangest features of this crisis is that some African countries have both unfilled hospital positions and unemployed, fully qualified health workers — at the same time. It sounds like a contradiction. It isn't.
The disconnect is usually financing, not people. Governments frequently can't afford to hire every graduate their training pipeline produces, even while facilities elsewhere are dangerously short-staffed. A newly qualified nurse who can't get a public-sector job at home has every reason to look abroad — turning domestic unemployment into an unintended feeder system for other countries' hospitals. That's a policy failure as much as a workforce one, and it's arguably more fixable than the salary gap, since it's about budget allocation and hiring pipelines rather than matching international pay scales dollar for dollar.
Rural areas absorb the worst of it. Health workers concentrate in capitals and major cities even before any of them consider emigrating; once international migration pulls further from that already-thin urban layer, remote clinics can be left with almost no experienced staff at all. Zambia, Malawi, Sierra Leone, and parts of Tanzania and Ethiopia all illustrate this same pattern at different scales — distribution, not just headcount, is a large part of what needs fixing.
What Actually Moves the Needle
There's no silver bullet here, but a few levers show up consistently in the policy literature, and Rwanda's relative success suggests they're not purely theoretical:
Link training expansion to actual hiring. More nursing graduates only helps if there are budgeted positions waiting for them — otherwise the pipeline just feeds emigration, as seen in Ghana and Zambia.
Fix retention basics. Competitive pay, safer staffing ratios, and functioning equipment address a large share of why people leave, independent of the salary gap with wealthier countries.
Make international recruitment ethical rather than extractive. Bilateral agreements that pair recruitment with investment in the source country's training system turn a one-way transfer into something closer to a partnership. Some destination countries have begun experimenting with exactly this — funding scholarships or training capacity in source countries as part of formal recruitment agreements.
Build genuine return pathways. Diaspora professionals who eventually want to come home need functioning systems to return to — recognized credentials, hiring pipelines, and competitive-enough pay to make the return worth it.
Treat the diaspora as an asset, not a loss. Remote mentorship, telemedicine collaborations, research partnerships, and diaspora-funded projects can put expatriate expertise to work without requiring anyone to physically relocate back.
Invest in task-shifting and mid-level cadres. Rwanda's expansion of what nurses and community health workers are authorized to do — reducing sole reliance on physicians for tasks that don't strictly require one — offers a template other lower-income systems have started to explore.
Address bonding schemes carefully. Several countries, including Ghana, have experimented with requiring newly trained doctors to serve domestically for a fixed period before becoming eligible to emigrate. These policies are controversial — critics argue they restrict individual freedom and can be circumvented — but they represent one of the few direct levers governments have pulled so far.
Brain Drain or Brain Circulation?
There's a more optimistic frame available here, and it's worth naming directly: the fact that African-trained doctors and nurses are this competitive on the global market is itself evidence of how strong the training is. Nobody recruits weak candidates internationally at this scale. The professionals leaving Nigeria, Ghana, Zimbabwe, Kenya, South Africa, Cameroon, and dozens of other African countries aren't leaving because they lack skill — they're leaving because their skill is valuable, and currently rewarded more generously somewhere else.
That reframes the policy question. It's not "how do we stop people from leaving" — that fight is close to unwinnable against the scale of the salary gap and the strength of existing migration networks. It's "how do we make staying, or eventually returning, a genuinely competitive option." Countries that manage to do that don't eliminate migration; they turn it into circulation — professionals leaving, gaining experience and capital abroad, and bringing some of it back, rather than a permanent one-way drain.
Africa isn't short on talent. It's short on the conditions that let that talent build a full career at home. Closing that gap — not closing the border — is the actual work ahead, and it will look different in Kigali than it does in Lagos, Freetown, or Cairo. There is no single continental fix, because there is no single African health system. There are dozens of them, each with its own combination of financing constraints, training capacity, political stability, and migration history — and each will need its own version of the same basic answer: give people a real reason to stay, and enough of them will.
