This document discusses strategies for preventing rheumatic heart disease. It outlines four levels of prevention: primordial, primary, secondary, and tertiary. Primordial prevention focuses on societal interventions to improve living standards and access to healthcare. Primary prevention aims to treat streptococcal pharyngitis with penicillin. Secondary prevention, the most commonly used strategy, provides ongoing treatment to those diagnosed with rheumatic fever to prevent recurrences. Tertiary prevention seeks to improve symptoms, prevent complications like heart failure, and provide interventions for issues like atrial fibrillation.
