About Public Health

According to the Association of Schools of Public Health, Public Health is the science of protecting and improving the health of communities through:
  • Education
  • Promotion of healthy lifestyles
  • Research for disease and injury prevention
Public health professionals analyze the effect on health of genetics, personal choice and the environment in order to develop programs that protect the health of your family and community. For more information visit the Association of Schools of Public Health website.
