In the epidemiological process, what is the first step?

• A. Identify the problem (assessment)
• B. Gather information
• C. Formulate a theory
• D. Formulate a plan

Answer: (A)

In epidemiology, you start by identifying the problem through assessment. This means clarifying what health issue is occurring, who is affected, where and when it’s happening, and how big the problem is. Defining the problem sets the purpose and scope for all the data you’ll collect next. Gathering information comes after, as you pull together surveillance data, case counts, and exposure histories to describe the magnitude and distribution and to start exploring possible determinants. Formulating a theory or hypotheses is something you move toward once you have data to explain the observed patterns, and planning a response or intervention comes later, after you’ve understood the problem and its context.
