Abstract

Universal Health Coverage (UHC) represents a global commitment to ensuring equitable access to quality 
healthcare without financial hardship. This review synthesizes evidence on geographic disparities, system 
resilience, and cross-country progress toward achieving UHC. Despite notable gains, urban–rural inequities 
persist, particularly in low- and middle-income countries, where rural populations remain underserved due to weak 
transport infrastructure, limited facilities, and economic constraints. Sustainability and resilience emerge as critical 
dimensions of UHC, particularly in the context of pandemics, economic shocks, and climate change. Strengthening 
health systems to withstand crises requires robust governance, emergency financing mechanisms, and adaptive 
service delivery frameworks that preserve essential care. Comparative analysis across income groups reveals that 
Nordic and other high-income countries achieved UHC through strong political consensus, equitable public 
financing, and integrated service delivery models. Middle-income countries continue to refine their pathways 
through social protection reforms and mixed financing mechanisms, while low-income countries advance 
incrementally, often constrained by fiscal and institutional limitations. Building resilience into UHC demands 
multisectoral action, climate adaptation strategies, and investment in long-term health system strengthening. The 
review concludes that achieving UHC globally requires sustained political commitment, inclusive policies, 
equitable financing, and adaptive capacity to ensure sustainability, quality, and universal access amid evolving 
global challenges.
