Public health surveillance is primarily used to do which of the following?

• A. Punish unhealthy behaviors.
• B. Systematically monitor health status to plan, implement, and evaluate PBH actions.
• C. Replace clinical diagnoses.
• D. Forecast individual patient outcomes.

Answer: (B)

Public health surveillance is the ongoing, systematic collection, analysis, and interpretation of health data to monitor the health status of a population over time. This information guides decisions about planning, implementing, and evaluating actions to protect and improve community health. It helps identify trends, detect outbreaks, and assess the impact of programs and policies, enabling better resource allocation and priority setting. It’s not about punishing individuals for unhealthy behaviors, and it doesn’t replace clinical diagnoses, which are made for individuals. Nor does it forecast outcomes for specific patients; instead, it provides population-level insights to shape public health actions.
