Preventive medicine focuses on preventing disease and keeping patients healthy. There are 3 levels of prevention: 1.Primary prevention: preventing disease before it occurs (eg, immunization to prevent disease, use of condoms to prevent sexually transmitted diseases); 2.Secondary prevention: detecting preclinical disease to start early treatment for better outcomes (eg, cancer screening, treating hypertension to prevent cardiovascular disease); and 3. Tertiary prevention: improving outcomes (quality of life, disease progression) in known disease (eg, use of aspirin after myocardial infarction to decrease recurrence, rehabilitation after a stroke).
