What is the ongoing systematic collection, analysis, and dissemination of health-related data to monitor health problems to facilitate their prevention or control?

• A. Public health monitoring
• B. Health surveillance system
• C. Epidemiology
• D. Surveillance

Answer: (D)

Surveillance is the ongoing, systematic collection of health data, its analysis, interpretation, and timely dissemination to those who can act on it, with the goal of monitoring health problems and guiding prevention or control efforts. This continuous cycle brings data from multiple sources, turns it into actionable insights, and shares findings through reports, alerts, or dashboards so interventions can be timely and targeted. It’s what lets public health officials detect outbreaks early, observe trends over time, allocate resources, and evaluate whether policies and programs are making a difference. The other terms describe parts or related ideas—the infrastructure that makes surveillance possible (a health surveillance system), a broader or differently framed activity (public health monitoring), or the scientific study of disease patterns and determinants (epidemiology)—but the described ongoing process of data collection, analysis, and dissemination for prevention and control is surveillance.
