The public health field has been recognized in the United States since the 1900s. In the period of 1900–1945, public health had a narrower interest. During the 1900s, public health was interested in measuring communicable diseases, educating the community about selected illnesses, handling food and water, recording vital statistics, and treating diseases. To pursue a profession in the field of health education and promotion, more than just acquiring credentials is required. The core responsibilities, competencies, and sub-competencies provide a comprehensive description of the profession, illustrating the skills necessary to perform the daily tasks as a public health educator or health education specialist. Professional public health associations ensure that public health educators maintain their professional credibility by addressing the multiple needs or matters that public health educators experience in their professional work. The federal government assumes an extensive job in the general well-being framework of the nation.
