Public Health

A career in public health encompasses a variety of occupations which are concerned with the social, psychological and physical welfare of the public. Masters and doctoral degrees are available.

Public health or community health educators examine conditions in industry, the environment and in housing and educate the public about communicable diseases and health care. In addition, they may develop community health services specifically tailored to the area's special needs.

Public health is the science and practice of improving the health and welfare of all people by promoting health and preventing and controlling disease. The work of public health professionals protects our water and food supplies, controls the spread of diseases such as whooping cough and polio and provides the government and public with essential information on health threats.
