Community Health Workers: The Backbone of Rural Healthcare

 

In many rural villages, the nearest clinic is hours away, and the nearest doctor is farther still. What these communities often have instead is a neighbor who has been trained to check a feverish child, visit a new mother, spot a malnourished toddler, and know when to refer someone to a health facility. These are community health workers (CHWs), and for millions of people they are the health system.

Who Are Community Health Workers?

Community health workers are frontline health cadres who live in the communities they serve. Africa CDC and partners describe them as the lowest-level health cadre, working within communities to promote health, prevent and control disease, and act as a bridge between households and the formal primary health care system, especially in underserved and hard-to-reach areas. Their roles vary by country but typically include health education, maternal and newborn home visits, immunization follow-up, screening for malnutrition, treatment of common childhood illnesses, disease surveillance, and referral.

The Global Picture: A Workforce Gap

The case for CHWs starts with a shortage. WHO projects a global shortfall of 11.1 million health workers by 2030, mostly in low- and lower-middle-income countries, with the biggest gaps in the African and Eastern Mediterranean regions. WHO has also warned that cuts in official development assistance could add about 600,000 to the projected health and care workforce shortage in Africa by 2030 compared with earlier estimates.

CHWs are one of the most practical ways to close part of that gap quickly. WHO's summary of the evidence, as cited by implementing organizations, is that CHWs delivering community-based care for infants and children in resource-limited settings can reduce neonatal, infant, and child mortality and illness from conditions such as malaria, pneumonia, and diarrhoea. The evidence also supports their role in maternal and newborn health, infectious diseases, noncommunicable diseases, and mental health.

WHO's guidance is clear that CHWs only deliver this when they are supported properly. Its 2018 guideline on optimizing CHW programmes, its policy guide on integrating CHWs into health systems, and its Global Curriculum Guide for CHWs (published 31 December 2025) all point to the same ingredients: structured training, supervision, fair and predictable payment, and full integration into primary health care.

Africa: Fast Growth, Unfinished Business

Africa shows both the promise and the problem. According to WHO's State of the Health Workforce in Africa 2026 report, there were an estimated 1.15 million CHWs in the region in 2024. They made up about 20% of all reported health workers and were the largest single occupation group among the tracer occupations. Of the total net increase in health workers between 2022 and 2024, about 45% (roughly 299,000) were CHWs, meaning they are driving the expansion of the workforce. Overall, the region's health workforce grew from 1.6 million in 2013 to 5.72 million in 2024, including those 1.15 million CHWs.

Yet the need remains very large:

• Disease burden vs workforce: Africa carries more than a quarter of the global disease burden but has only a small share of the world's health workers. WHO's Regional Director for Africa has cited a projected shortfall of more than 6 million health workers by 2030. 

• The two-million target: In February 2026, African Union health and finance ministers committed to building a two-million-strong CHW workforce by 2030 and called for urgent, sustained investment, in a communique adopted in Addis Ababa on 13 February 2026. Africa CDC estimates that this expansion would cost about $5.4 billion a year.

•   A modelled payoff: Africa CDC and partners estimate that scaling up CHW programmers could save up to 151 million lives by 2030, mainly by reducing newborn and under-five deaths, and that CHWs can deliver up to US$10 in return for every US$1 invested. These are modelled estimates, not observed results, but they show the scale of the potential.

• Country commitments: Nigeria's Minister of Health announced a goal of deploying 100,000 salaried CHWs, integrated into state health systems, by 2027.

How CHWs Are Employed Matters

One of the most useful findings comes from a 2025 analysis of CHW requirements in Africa. Using a threshold of 25.2 CHWs per 10,000 people, the researchers estimated a gap of 1.46 million CHWs in 2022. But if all existing CHWs worked full time, the needs-based shortage would shrink to about 210,000. The researchers stress that these densities are not planning targets and that each country should use WHO tools to estimate its own needs. The message is still important: part-time, unpaid, or poorly supported CHW roles hide a large amount of unused capacity.

This matches the direction of African policy. WHO's proposed Africa Health Workforce Agenda 2026–2035 calls on countries to progressively integrate CHWs, with CHW programmes based on health system needs, an integrated care approach, and clear selection criteria. The WHO Africa Region's CHW framework emphasizes structured training, effective supervision, predictable remuneration, and full integration into national primary health care. A convening of 21 countries in Addis Ababa in February 2026 likewise urged governments to commit to predictable remuneration for CHWs under government oversight, noting that average domestic health spending in the region remains below the 15% Abuja Declaration target.

Somalia: One National System, Built on Local Lessons

Somalia is a good example of both the opportunity and the difficulty.

 A new national strategy

On 6 April 2026, the Federal Government of Somalia launched the Somalia Community Health Strategy 2025–2029, led by the Federal Ministry of Health and Human Services and developed with UNICEF, WHO, the World Bank, the Global Fund, Africa CDC, civil society, and community representatives. The strategy aims to create one harmonized national community health system under one national plan and one leadership. The Minister described the problem it addresses: community health in Somalia has long been fragmented, with different partners, different cadres, and different training.

The national cadre at the centre of this is the Female Health Worker, delivered through the Marwo Caafimaad programme under the Ministry of Health. Rollout has reached some federal member states, but not all.

CHWs in emergencies

CHWs have already proved their value in crises. WHO Somalia and the Federal Ministry of Health deployed 1,538 CHWs, supported by 171 district rapid response teams, for COVID-19 surveillance and community awareness, and then expanded the programme with another 626 CHWs recruited through state-level partners. 

Supportive supervision through the rapid response teams provided accountability for community-based surveillance, including in camps for displaced people.

What a rural programme learned

A programme run by the International Rescue Committee within the EQUAL Research Consortium (with SORDI and the Johns Hopkins Center for Humanitarian Health), in eight villages 20 to 65 km from the nearest town of Dhusamareb, offers practical lessons. As summarised in a policy brief, 34 trained female CHWs were recruited from the same villages as their clients, in places with no previous health workers:

- CHW competency scores exceeded the 80% benchmark from the third assessment onward and stayed there.

- Retention was 98% over 24 months.

- Community-based care complemented, rather than replaced, women's use of health facilities.

The lessons the programme drew for the national strategy were: recruit locally, because shared language, religion, and social ties make home visits acceptable; use lower caseloads in rural areas (the programme used 1 CHW per 50 households, compared with a national standard of 1 per 150 designed for denser areas, and in one village households were 8 to 15 km apart); pay CHWs fairly and reliably (the programme paid $100 a month, while the government rate is $120, and many CHWs in other programmes go unpaid); and invest in supervision.

A 2026 qualitative study of CHWs delivering maternal and newborn care in rural Somalia (a preprint, not yet peer reviewed) adds an important caution. It found that CHW effectiveness depends not only on technical skill but on social embeddedness, informal financial obligations, and gendered household power dynamics. Its authors warn that, as the national programme scales up, it risks burdening already marginalized women with uncompensated social labor unless these realities are built into programme design.

What This Means for Public Health Practitioners

1. CHWs extend the reach of every programme we run. Malaria case management, immunization follow-up, nutrition screening, hygiene promotion, and cholera response all depend on someone in the community who is trusted and trained.
2. They are the eyes of community-based surveillance. Somalia's experience shows that trained CHWs, supported by rapid response teams, can detect and report alerts early, in places formal facilities rarely reach.
3. Pay, supervision, and integration decide results.  Across WHO guidance, African Union commitments, and the Somali field experience, the same message appears: unpaid, unsupervised volunteers are not a workforce.
4. Design for the local context. Caseloads, travel time, security, and gender norms differ widely, so national standards need to be adapted to rural and displaced settings.
5. CHWs are not a substitute for the health system. Their effectiveness depends on referral links, medicines and supplies, and facilities that can receive the patients they send.

The Bottom Line

Community health workers are not a cheap shortcut; they are a core part of a functioning health system. Africa now has more than a million of them and a political commitment to double that number by 2030. Somalia has a national strategy to turn a fragmented set of programmes into one system. Whether these commitments change lives will depend on the unglamorous basics: fair pay, steady supervision, reliable supplies, and a clear place for CHWs in national health plans and budgets. Where those basics are in place, the evidence suggests a trained neighbour can be the difference between a child reaching care in time and not reaching it at all.
