There are three main types of prevention in epidemiology:
1. [Primary Prevention](href): This aims to prevent the disease before it occurs. It involves interventions like vaccinations, health education, and lifestyle modifications. 2. [Secondary Prevention](href): This focuses on early detection and prompt treatment to halt the progression of a disease. Screening programs and early diagnosis are key components. 3. [Tertiary Prevention](href): This aims to reduce the impact of an already established disease by restoring function and reducing disease-related complications. Rehabilitation programs and chronic disease management fall under this category.
