Abstract
Malaria remains a significant public health challenge in South Africa's Eastern Cape Province, where vector control strategies have been implemented to reduce disease transmission. A longitudinal study design was employed, analysing changes in health expenditures related to malaria control initiatives using mixed-effects regression models with robust standard errors to account for temporal correlations. There was a notable reduction in healthcare costs associated with malaria cases among the population exposed to LLINs and IRS, indicating an effective long-term strategy. The study confirms that sustained vector control measures are essential for maintaining cost-effective public health outcomes against malaria. Continuation of current vector control programmes is recommended alongside periodic evaluations to ensure optimal resource allocation.
