What is Public Health?
Share |


“The science and art of preventing disease, prolonging life, and promoting health through the organized efforts and informed choices of society, organizations, public and private communities, and individuals.” CEA Winslow, Founder, Yale School of Public Health

Promoting and protecting the health of people in the communities where they live, learn, work, and play is what public health is all about. The practice of public health is wide-ranging. The core public health disciplines are health policy and management, biostatistics, environmental health sciences, epidemiology, and social and behavioral sciences.

Public health touches every aspect of our lives and addresses:

  • Racial and ethnic health disparities
  • Infectious and chronic disease prevention
  • Injury and violence prevention
  • Nutrition and safety standards for food
  • Sanitation
  • Oral health
  • Environmental health, including clean air and water
  • Addiction prevention
  • Workers’ health

The work of public health is accomplished by community health workers, healthcare providers, lawyers, researchers, legislators, policy advocates, public health and safety agency administrators, and educators, among many others.


CPHA brings together people in all these disciplines to work for the public health of Connecticut’s residents.
