Preventive healthcare is categorized into three levels:
Primary prevention: This level aims to prevent disease before it occurs. Examples include immunizations, health education, and lifestyle interventions. Secondary prevention: This focuses on early disease detection and intervention to prevent progression. Examples include screenings and regular health check-ups. Tertiary prevention: This level aims to manage and mitigate the impact of established diseases to improve quality of life. Examples include rehabilitation and chronic disease management programs.
