This study delves into the relationship between progressive health spending and malaria outcomes in Nigeria, aiming to uncover the impact of financial investments on disease management. Malaria remains a significant public health challenge in Nigeria, with substantial resources allocated to combat the disease annually. However, the effectiveness of health spending in curbing malaria incidence and mortality rates remains unclear. Through a comprehensive analysis of healthcare expenditure trends and malaria outcomes, this research seeks to elucidate the extent to which progressive health spending influences malaria prevention, treatment, and control measures. Drawing upon national health expenditure data and malaria surveillance statistics, the study employs quantitative methods to examine the association between health expenditure patterns and malaria incidence and mortality rates over time. The findings shed light on the effectiveness of financial investments in mitigating the burden of malaria and inform evidence-based policy decisions aimed at improving disease management strategies in Nigeria.
