How are prevention and screening related in health practice?

• A. Screening prevents disease through vaccination.
• B. Prevention aims to reduce disease incidence; screening detects disease early in asymptomatic individuals as part of prevention.
• C. Prevention only involves health education and has no role in disease incidence.
• D. Screening is unrelated to prevention.

Answer: (B)

The main idea is that prevention covers actions that reduce disease burden, and screening is a preventive activity that looks for disease in people without symptoms so that early intervention can occur. By detecting conditions early, treatment can start sooner, reducing complications, morbidity, and often mortality, which fits preventive aims. Screening isn’t vaccination and doesn’t by itself stop a disease, but it enables timely steps that prevent progression and harm, making it a key part of prevention. The other statements either confuse screening with a preventive measure that directly blocks disease (like vaccination), limit prevention to education, or say screening has no preventive role, which misses how early detection changes outcomes.
