The following information was gathered from a variety of sources including the www.whatispublichealth.org website, the Bureau of Labor Statistics, and interviewing professionals in the field of public health.

Public health is the science of protecting and improving the health of communities through education, promotion of healthy lifestyles, and 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.

Public health focuses on protecting entire communities or populations, rather than the individual. These communities can be small or large. This science field has a focus on improving the health of populations through education or sharing information, researching disease and injury prevention, and through encouraging healthy lifestyles. Developing methods to prevent the reoccurrence of health issues through implementing policies and educational programs is a main focus of the public health field. This is different than the traditional field of medicine that typically addresses patients after they become injured or sick.

Educational Requirements for Public Health Jobs

Professionals in the public health field can work for both private and public organizations. Within the public sector, there are federal, state and local organizations. Examples of federal or government organizations include the Centers for Disease Control and Prevention, the American Medical Association, the Food and Drug Administration, and the National Institute for Health. Examples of local health groups include any non-profit organizations, colleges, research and development institutes, and even hospitals. Examples of non-profit organizations would include the American Cancer Society or the Red Cross. In the private sector there are positions available such as working in control trials for health insurance or pharmaceutical companies. 

Public health degree programs

Since public health is so broad there are a variety of bachelor’s degrees one can obtain to pursue this field. Some chose to earn their bachelor’s in public health and others may chose a degree that relates to the specific area of public health they’re interested in. For example, for a person who wants to pursue a job in biostatistics or epidemiology, a degree in math or biology may be appropriate. A nutrition or dietetics degree is suitable for those who want to pursue the nutrition field within public health. For those interested in health services administration, a marketing or business degree is an excellent fit. A psychology, sociology, or anthropology degree would fit well for someone interested in a behavioral science or global health career. For those who want to be involved in health education, an educational degree would be an appropriate match.

The Bachelor of Science and the Master of Public Health degree incorporates the complexities of the health care system, health care law, information systems, financial management, and human resources management. Recurrent changes within the health care system, such as with the HIPAA privacy laws and new regulations regarding the adoption of electronic health record systems, have not only made the public health care arena an interesting place in which to work, but also a complex one that requires professionals who are knowledgeable in all areas of health care.

Training for public health jobs

Most programs require internships so students are able to gain hands on experience in this field. The types of internships vary based on the program and the area of emphasis in public health an individual is pursuing. Internship experiences usually vary from six to nine months in duration. Oftentimes several shorter (perhaps two to three month) internships are required so students can get experience working in a variety of settings. Settings may include local or state health departments as well as hospitals.
