Which of the following is an annual use of surveillance information?

• A. Describing natural history of diseases
• B. Setting research priorities
• C. Archival research describing disease distribution
• D. Testing hypotheses

Answer: (B)

Annual use of surveillance information centers on turning current data into plans for the coming year. Surveillance keeps a pulse on how diseases and health events are occurring now—who is affected, where, and how these patterns are changing. Public health leaders use that timely information to set priorities for research, prevention, and resource allocation for the next year. That’s why selecting research priorities fits best: it directly translates up-to-date surveillance findings into a strategic agenda and funding focus for the year ahead.

Describing natural history concentrates on how a disease progresses within individuals, which is more about understanding illness trajectories than yearly planning. Archival research describing disease distribution looks at past patterns rather than current-year needs. Testing hypotheses is a research activity that can occur at various times and isn’t inherently tied to yearly planning based on surveillance data.
