Public health surveillance systems are crucial for monitoring disease prevalence and implementing effective interventions in Ghana. A meta-analysis approach was employed using publicly available data from multiple sources. Panel-data estimation techniques were applied to assess the efficacy and reliability of surveillance systems over time. The analysis identified a significant trend (p < 0. 05) in reduced incidence rates for common communicable diseases across different regions, indicating improved monitoring capabilities. The findings suggest that enhanced data collection methods improve the accuracy of risk assessments and inform targeted public health interventions. Further research should focus on integrating surveillance systems with community feedback mechanisms to enhance coverage and effectiveness. Treatment effect was estimated with logit (pᵢ) =₀+^ Xᵢ, and uncertainty reported using confidence-interval based inference.
