Most African health systems are replicas of what was inherited from the colonial era and are therefore unevenly weighted toward privileged elites and Urban centers. Improved health status leads to increased productivity, educational performance, higher life expectancy, savings and investments, and decreased debts and expenditure on health care. Ultimately this would lead to greater equity, economic return, and social and political stability. The health impacts of climate change can occur through a number of direct and indirect causal pathways, and the severity is in part determined by the adaptive capacity of the population. Those groups particularly at risk include poorer countries and communities, those geographically vulnerable to extreme weather events, and those highly dependent on agriculture for their livelihood.The paper examines the impact of public health expenditure, and poverty among the general populace. The trend of the country human development index and public expenditure on health were analyzed using correlation coefficient and regression analysis and simple descriptive analysis. The findings reveal that the variations in the human development index could be traced to the budget estimates
