Q

This is a primary use of data-driven public health decision-making. The continuous, systematic collection, analysis and interpretation of health-related data is needed to plan, implement, and evaluate public health initiatives.
● Data allows public health officials to detect trends, outbreaks, and patterns of diseases in real time. Timely and accurate surveillance allows for rapid responses to potential health threats, preventing further spread and minimizing their impact on communities.

Q

Through data-driven decision-making, public health interventions can be continuously assessed and evaluated for their effectiveness. Data provides concrete evidence of what works and what may not, allowing policymakers to make informed adjustments to improve outcomes and allocate resources more efficiently.
