What is Public Health?


The CDC Foundation defines public health as the “science of protecting and improving the health of families and communities through promotion of healthy lifestyles, research for disease and injury prevention, and detection and control of infectious diseases.”

With such an all-encompassing scope, it’s easy to see why public health is a field that features a variety of careers at all levels that focus on healthcare. And because public health is concerned with neighborhoods and entire nations your goal will be to educate and implement policy and research on a wider scale than on the welfare of the individual. So whether you want to track down the causes of disease as an epidemiologist or teach the public how to avoid getting sick as a health educator, there is a public health career that will fit your unique skill set.

What You Can Do with a Public Health Degree


Because public health is such a broad field it’s likely you’ll find an area that fits your interests. Whether you want to further medical advances by doing research, or creating public policy for your city, here are the major areas you can enter once you earn a degree in public health.

  • Biostatistics and Health Informatics
  • Community Health
  • Epidemiology
  • Environmental Health
  • Global Health
  • Policy and Health Management
  • Health Communications and Public Relations
  • Pediatric Health
  • Social and Behavioral Health
  • Minority Health
  • Nutritional Health

The job you’ll do in these fields is generally informed by where you’ll work. There are four common settings for those who desire to enter into a public health career:

  • Public facing careers include government jobs such as health administration and public nursing.
  • Non-profit careers focus on a particular population or health concern.
  • Academic focused public health careers include research and teaching.
  • Private settings mean careers in the private sector, such as insurance companies, pharmaceuticals or healthcare institutions such as hospitals or nursing care homes.


History of Public Health

Basically public health has evolved as people and society have evolved. If there is no pollution for example, pollution-related disease would not be an issue. But as humans evolve both for good and not, and industry and technology inform the issues that affect them, their environment and their quality of life, change and develop too.

In the early 1900s health threats were driven by poor hygiene, sanitation and nutrition as well as limited healthcare for infants and a preponderance of workplace related injury where no regulations were in place. Early progress in public health consisted of making vaccines and antibiotics available to the masses, as well as identifying the risk factors that drove mortality rates. These advances laid the stepping stones to epidemiology studies and created changes in public health training and programs.

As federal, state and local public health expanded in the early part of the century, the government’s input increased and it assumed more and more responsibility for health research and programs. Private sector organizations also expanded their efforts in public health awareness, with projects focusing on specific diseases, such as hookworm and tuberculosis.

State health departments and associations began to develop and lobby for safer foods and drugs. The American Dental Association endorsed water fluoridation and labor unions pushed for workplace laws to keep workers safe.

In 1930, Congress established the NIH and the Food and Drug Administration, while the Center for Disease Control (CDC) was established in 1946. Today the public health infrastructure is a combination of government, academic and private and non-profit efforts to keep the nation—and world—safer.

How to Get Started in a Public Health Career


A bachelor’s degree may suffice for some public health careers but others—especially if you want to move into academic or government and administrative roles—may require you to earn your MPH.

But, if you have some experience in more entry- and mid-level healthcare roles such as medical billing and coding or medical records, you may be at an advantage. Places such as insurance companies and other healthcare facilities look for people with basic knowledge of Medicare and Medicaid, the ICD-11, medical records management, medical billing and coding, the Health Insurance Portability and Accountability Act and Current Procedural Terminology to help keep their systems running smoothly and efficiently and your on-the-job skills may be a boon to your seeking employment in the field.
