Trends in government and donor funding for vertical and horizontal community health worker programmes in sub-Saharan Africa.
Community health worker (CHW) programmes are central to primary healthcare (PHC) in sub-Saharan Africa (SSA). Yet who pays for them, how much, and whether funds favour vertical (single-disease) or horizontal (broader-focus) programmes remains unclear. This study examined trends in donor and government financing for CHW programmes across SSA.
We conducted a secondary analysis of publicly available data. Organisation for Economic Co-operation and Development Creditor Reporting System (2002-2022) projects were screened and classified as vertical or horizontal through standard definitions and manual review. Government spending in 37 SSA countries (using WHO Global Health Expenditure Database (2016-2022) was estimated by applying maturity-based allocation percentages to preventive and outpatient curative functions. We described trends, donor composition, vertical-horizontal shares and the annual financing gap against published cost benchmarks.
Between 2002 and 2022, global external assistance for CHW programmes totalled US$14.4 billion, SSA receiving 76% (US$11.0 billion). Of donor funds to SSA, 76.4% supported vertical programmes, although these made up fewer than 20% of projects; horizontal programmes received just 14.7%. Annual external assistance rose from ~US$0.28 billion (2016-2019) to ~US$1.83 billion (2020-2022), with over 90% directed to vertical or COVID-19-related efforts. Government spending across 37 SSA countries totalled ~US$1.4 billion (2016-2022). This represented less than 20% of total CHW funding but a greater share directed to horizontal services (54.6%). The annual financing gap remained between US$4.7 billion and US$4.3 billion.
CHW financing in SSA is donor-dominant and vertically oriented; domestic allocations are limited but relatively more horizontal. Closing the funding gap will require larger, predictable government budgets for CHWs, better-aligned partner support and stronger expenditure tracking to sustain PHC and advance universal health coverage.
