TOWARD SUSTAINABLE HEALTH SYSTEMS: IMPROVING INFRASTRUCTURE IN UNDERDEVELOPED REGIONS

Global health disparities remain a pressing challenge, with stark contrasts between high-income countries and low-resource settings. For example, in 2003, life expectancy at birth in Japan was 85 years with a per capita health expenditure of $550, whereas in Sierra Leone it was only 36 years, with just $3 spent per capita. Despite international commitments such as the 2000 UN Millennium Summit, many low-income countries continue to struggle with insufficient healthcare infrastructure, inadequate personnel, and limited resources. Africa, bearing 85% of the global disease burden, accounts for only 11% of global health expenditure and faces a severe health workforce deficit exceeding 4.3 million in 27 countries across Africa and Asia. This shortage exacerbates poor health outcomes, contributing to high infant mortality and limited access to essential services. Additionally, out-of-pocket health expenses frequently drive millions into poverty, further deepening inequities. Addressing these challenges requires resilient, efficient health systems in under-resourced regions, improved access to skilled personnel, expanded infrastructure, and reduced financial barriers. Health-related migration underscores the global dimension of healthcare disparities. This study highlights persistent global health inequalities and advocates for coordinated efforts to strengthen health systems and close the equity gap in low-income countries.
