Preventive strategies can be categorized into three levels:
Primary Prevention: Aims to prevent the onset of disease before it occurs. This includes measures such as vaccination, health education, and lifestyle modifications. Secondary Prevention: Focuses on early detection and intervention to halt the progression of disease. Screening programs and regular health check-ups are examples of secondary prevention. Tertiary Prevention: Involves managing and reducing the impact of an established disease. Rehabilitation and support groups fall under this category.
