Which is an example of primary prevention?

• A. Screening for early disease detection
• B. Rehabilitation after illness
• C. Immunization programs
• D. Management of chronic diseases

Answer: (C)

Preventing disease before it happens is the goal of primary prevention. Immunization programs fit this because vaccines stimulate the body’s immune system to recognize and fight specific pathogens, so people do not get the disease in the first place. By preventing the illness from occurring, vaccines reduce disease incidence across the population. In contrast, screening for early disease detection aims to find illness early in people who may not have symptoms (secondary prevention). Rehabilitation after illness focuses on restoring function and preventing further disability (tertiary prevention), and managing chronic diseases centers on controlling the condition and preventing complications (also typically considered a form of tertiary prevention).
