Donor Funding Volatility and the Sustainability of HIV/AIDS Programmes in Sub-Saharan Africa: A Secondary Data Analysis and Policy Review

Abstract Background International development assistance has enabled major gains in HIV treatment, prevention, laboratory systems and community outreach across Sub-Saharan Africa. Yet aid volatility, fiscal pressure in donor countries and changing global priorities have exposed a structural weakness in health systems where recurrent HIV programme costs remain substantially externally financed. This study examined how reductions or uncertainty in USAID-supported and broader donor health funding influence health financing priorities and opportunities for health systems strengthening in Sub-Saharan Africa. Methods The manuscript was developed from an unpublished master’s dissertation and an expanded article draft. A qualitative-dominant secondary-data design was used. Quantitative information on aid trends, selected country dependence, public health expenditure and health indicators was synthesized descriptively. Qualitative evidence from institutional reports, peer-reviewed literature and policy documents was analyzed thematically using health financing, donor dependency and health system resilience. Results The analysis identified HIV/AIDS treatment, medicines and supply chains, community outreach, maternal health, vaccination and health workforce functions as the most exposed areas when external funding falls abruptly. Countries with broader tax capacity, established insurance pools, stronger public financial management and integrated primary healthcare platforms appear better positioned to absorb funding shocks. Conversely, settings with high external-aid shares, fragmented procurement systems and weak fiscal space face elevated risks of stock-outs, staff attrition, service interruption and widening inequities. Conclusion Donor transition should be planned as a staged health-system reform rather than a short-term budget exercise. Sustainable transition requires predictable multi-year funding pathways, domestic resource mobilization, pooled procurement, integration of HIV services into primary healthcare, protection of community systems and stronger accountability for public health expenditure.
