Public health surveillance systems are crucial for monitoring infectious diseases in Ethiopia, where healthcare infrastructure can be limited. A quasi-experimental design was employed with a sample of 150 healthcare facilities randomly selected from regions across Ethiopia. Surveys were conducted to measure system adoption using standardised tools. Among the surveyed facilities, 72% reported adopting at least one aspect of the surveillance system, indicating moderate levels of integration into routine operations. The findings suggest that while there is some uptake of public health surveillance systems in Ethiopia, more support and training are needed to enhance their effectiveness. Health authorities should prioritise capacity building for healthcare providers to improve adoption rates and system performance.
