A key purpose of surveillance data besides monitoring health problems is to

• A. Dissemination to inform policy and prevention
• B. Keep data private
• C. Training new staff
• D. Replace clinical care

Answer: (A)

Surveillance data are used not only to track health problems but also to drive policy and prevention actions. When data are shared with policymakers, program planners, and public health officials, they can identify priorities, justify funding, design and target interventions, and monitor how well those actions work over time. In essence, the value of surveillance lies in turning observations into concrete steps that prevent disease and protect the community.

Keeping data private is important for confidentiality, but the question asks about a purposeful use of data beyond monitoring. Training new staff is a useful activity that can rely on data, yet it isn’t the primary aim of surveillance data. Replacing clinical care isn’t appropriate because surveillance supports public health actions and system planning, not direct clinical treatment.
