Key Concepts

Disease Prevention

Disease prevention involves measures to reduce the occurrence and spread of illnesses in populations. This includes vaccination programs, sanitation, and health education to minimize risk factors and protect community health.

Health Promotion

Health promotion focuses on encouraging healthy behaviors and lifestyles through education, policy-making, and community initiatives. It aims to improve overall well-being and prevent chronic diseases by addressing social and environmental determinants.
