Public Health Intervention

Meaning

A Public Health Intervention is any planned, systematic action or program implemented at a population level, rather than an individual clinical level, with the explicit goal of protecting, promoting, or restoring health and preventing disease and disability. These interventions are evidence-based, guided by epidemiological data, and can range from large-scale vaccination campaigns and mandatory food safety regulations to community-based health education programs aimed at improving lifestyle behaviors. Their efficacy is measured by their impact on population-level health metrics and the reduction of health disparities.
