Based on the framework of preventive medicine (three levels and five stages), this course includes the following contents. Primary prevention aims for health promotion (e.g., nutrition and exercise, etc.) and specific protection (e.g., vaccination, removing environmental risk factors, preventing occupational and accidental injury). Secondary prevention aims for early diagnosis and proper treatment (e.g., identification of preclinical cases, disease screening, and health checkup). Tertiary prevention aims to restrict disability (e.g., treatment to prevent disease worsening, complications, and development of secondary disease) and rehabilitation (e.g., psychological, physiological, and occupational therapy and long-term care).
