A) Primary prevention
B) Secondary prevention

D) Health promotion

Secondary prevention focuses on individuals who are experiencing health problems or illnesses and who are at risk for developing complications or worsening conditions. Activities are directed at diagnosis and prompt intervention. Primary prevention precedes disease or dysfunction and is applied to people considered physically and emotionally healthy. Health promotion includes health education programs, immunizations, and physical and nutritional fitness activities for healthy people. Tertiary prevention occurs when a defect or disability is permanent and irreversible. It involves minimizing the effects of long-term disease or disability through interventions directed at preventing complications and deterioration.
