Persisting absence of human rights, widening inequality, and social justice in healthcare delivery systems within and between countries present significant challenges to the focus and practice of contemporary public health. This chapter compares how cases of human rights, equity, and social justice are integrated in America's and Nigeria's healthcare policies. Qualitative research and case study design were adopted. Data were collected from secondary sources, such as reviewed literature, textbooks, journal articles, government reports, and internet. Content and critical case studies analysis methods were utilized to analyze, explain, and compare America's and Nigeria's health policies. Findings reveal absence of human rights, equity, and social justice among sub-groups in healthcare service delivery in America and Nigeria. The chapter concludes by suggesting that human rights, equity, and social justice should be integrated into health policies of America and Nigeria in order to make access to healthcare service delivery a right for citizens.
