What Are the Key Strategies for Disease Prevention?
Disease prevention in public health can be categorized into three levels: primary, secondary, and tertiary prevention.
Primary prevention aims to prevent disease before it occurs. This includes measures like vaccination, health education, and lifestyle modifications. Secondary prevention focuses on early detection and treatment of diseases to halt their progression. Screening programs for conditions like cancer and hypertension are examples. Tertiary prevention aims to reduce the impact of an already established disease by restoring function and reducing disease-related complications.
