Preventive measures such as immunizations and water fluoridation are examples of which type of prevention?

The correct answer is D: Primary prevention. Primary prevention aims to prevent disease before it occurs by addressing underlying causes and risk factors. Immunizations and water fluoridation fall under this category as they target the root causes of diseases to prevent them from developing. Quaternary prevention (A) focuses on avoiding unnecessary medical interventions, tertiary prevention (B) aims to prevent complications and manage existing conditions, and secondary prevention (C) involves early detection and treatment to halt disease progression. In this scenario, primary prevention is the most appropriate choice as it aligns with the proactive nature of immunizations and water fluoridation.
