Who is considered the father of preventative medicine?

• A. Hippocrates
• B. Louis Pasteur
• C. Edward Jenner
• D. Elizabeth Blackwell

Answer: (A)

Preventive medicine is about keeping people healthy by focusing on lifestyle, environment, and sanitation before illness occurs. Hippocrates is often credited as the father of preventive medicine because he stressed that health depends on daily habits and the surrounding environment. He connected factors like diet, exercise, sleep, and the quality of air and water to health and disease, and he advocated prevention through balanced living and clean conditions long before modern medical science formalized these ideas.

The other figures contributed important breakthroughs—vaccination and germ theory, advances in medical education, and broader public health progress—but the enduring emphasis on preventing disease through how we live and how our surroundings influence health points to Hippocrates.
