Answer (a) — incorrect: The disease process would have already been initiated among the individuals identified by the screening program. Primary prevention is characterized by individual or community efforts to stop the disease process from initiating (Aschengrau & Seage p. 413-14).

Answer (b) — correct: The rationale for the screening program is that it will identify asymptomatic persons with Susser Syndrome and provide early treatment so that the expression of the disease will be less severe, which is characteristic of secondary prevention (Aschengrau & Seage p. 414-15).

Answer (c) — incorrect: A tertiary prevention program is implemented after a clinical diagnosis has been confirmed to alleviate suffering and minimize complications of the disease. The screening program you hope to design for Susser Syndrome will identify persons who are asymptomatic and have not yet been diagnosed.
