Do medical spending and income reduce the prevalence of human immunodeficiency virus and tuberculosis? A study on Sub-Saharan Africa

Several countries in sub-Saharan Africa (SSA) suffer from economic hardship and high unemployment rates; furthermore, this region has higher rates of human immunodeficiency virus (HIV) and tuberculosis (TB). This study examined the relationships between HIV and TB, income, and total medical spending and its components, private and public healthcare expenditure, for 41 SSA countries. Random and fixed-effects models were utilized in this study to explore relationships by studying time series and cross-sectional panel data obtained from the World Bank. Results demonstrated that there is a positive relationship between HIV and unemployment and a negative relationship with income and medical spending. We also observed that, when private and public medical expenditures are compared, private medical expenditures alleviate the HIV epidemic. Considering the association with TB, income, total, and its components, private and public medical expenditures are negatively related. Since prevention of such life-threatening diseases as HIV and TB becomes vital to find remedies for, there is a need for more government initiatives, including job creation, increased productivity, and increased income levels, which can be seen as preconditions in fighting and controlling HIV and TB.
