Epidemiology studies the distribution and determinants of health-related states in populations.
Levels of Prevention
- Primary Prevention: Preventing disease onset (e.g., immunizations, health education, sanitation).
- Secondary Prevention: Early detection and prompt treatment (e.g., screening tests, mammograms, PAP smears).
- Tertiary Prevention: Rehabilitation and minimizing disability (e.g., physical therapy post-stroke, diabetic foot care).
