The World Health Report provides research for universal health coverage and it focuses on the importance of this research in making progress towards universal health coverage. In addition,it uses case studies from around the world to identify the benefits of increased investment in health research by low-income and middle-income countries. It also proposes ways to further strengthen this type of research. This report explains how the resolution adopted by all World Health Organization (WHO) Member States embraces the two facets of universal health coverage: the provision of and access to high-quality health services,and financial risk protection for people who need to use these services. “Health services” in this report means methods for promotion,prevention,treatment,rehabilitation and palliation,encompassing health care in communities,health centers,and hospitals. The term includes ways of taking action on social and environmental determinants both within and beyond the health sector. Financial risk protection is part of the package of measures that provides overall social protection.
