What is Public Health?

C. E. A. WinslowIn 1920, C.E.A. Winslow developed an appropriate definition of Public Health: “The science and art of preventing disease and promoting health and efficiency through organized community effort.”

Public health is about each one of us taking the responsibility for improving the health of the public, our community’s health. Doctors treat individual patients for a specific disease or injury. Public health professionals monitor and diagnose the health concerns of entire communities and promote healthy practices and behaviors to assure that populations stay healthy.

Public health is a field comprised of many professional disciplines such as medicine, dentistry, nursing, optometry, nutrition, social work, environmental sciences, health education, health services administration, and the behavioral sciences.

The year 1996 marked the 200th anniversary of Edward Lister’s discoveries which resulted in the global eradication of smallpox.

The Centers for Disease Control and Prevention, a world renowned public health organization, celebrated its 50th anniversary in 1996.

The four major eras in the United States public health history are:

  1. Prior to 1850 – Epidemics: avoidance and acceptance
  2. 1850 to 1949 – Sanitary reform through state and local infrastructure
  3. 1950 to present – Gaps in medical care and the expanding agenda
  4. 2001 to present - Terrorism - biological and chemical; intentional injury
    Chronic disease prevention and management
