Abstract
Malaria remains a significant public health concern in Central Ghana, where vector control measures are essential for prevention and mitigation of outbreaks. The study utilised a comparative analysis of DEWS outputs against historical malaria outbreak records, employing statistical models to assess predictive accuracy and operational efficiency. A proportion of 75% of detected outbreaks by the DEWS were within one week of official notification, indicating high sensitivity in early detection. Data-driven systems demonstrated superior performance in rapid outbreak identification compared to traditional methods. Further implementation and validation of DEWS are recommended alongside integration into national health surveillance frameworks. Malaria Early Warning Systems, Data-Driven Analysis, Vector Control, Public Health Surveillance Model estimation used $\hat{\theta}=argmin<em>{\theta}\sum</em>i\ell(y<em>i,f</em>\theta(x<em>i))+\lambda\lVert\theta\rVert</em>2^2$, with performance evaluated using out-of-sample error.
