Abstract
Public health surveillance systems in Ethiopia aim to monitor and respond to infectious diseases effectively. However, their reliability and efficiency vary over time. Bayesian Hierarchical Models were applied longitudinally across multiple surveillance sites in Ethiopia to assess variability and effectiveness of reporting metrics. The model revealed a significant decline (p < 0.05) in under-reporting rates from baseline to follow-up periods, indicating improved system performance over time. Bayesian hierarchical models provided robust insights into the dynamics of public health surveillance systems in Ethiopia, enhancing their reliability and responsiveness. Continued use of Bayesian methods for monitoring should be supported with further research on model validation and practical implementation.
