The field of public health entails prevention and education of the general public to help improve the overall health and reduce risks to a population, as opposed to the provision of individual medical treatment to one patient at a time.

In other words, people who work in public health do not diagnose or treat patients on an individual basis like doctors and nurses do in a clinical setting.

The Duties of Public Health Professionals

Public health professionals research and track health trends including behavioral, biological, and environmental factors.

They then utilize that research to help predict and prevent future health events or problems that could impact the health of the general population. Public health also includes the education of the public on ways to defend themselves against health risks.

Many public health workers have desk jobs in an office setting, while others may be dispatched out into the community for hands-on work with a given population. Workers may travel to outbreak areas or other events to help manage the spread and prevention of a disease on the front lines.

The Different Types of Jobs Available

Public health combines many other disciplines and skills within the healthcare industry to offer a variety of occupations.

Within the public health organizations and government health agencies, there are hundreds of professionals such as scientists, medical lab workers, biostatisticians, medical researchers, epidemiologists, medical doctors, and more, all working together to help fight the next threat to the nation’s health.

Additionally, because it combines so many different disciplines, outside of clinical medicine, public health is a good field for people who also have an interest in anthropology, science, biology, mathematics, statistics, and epidemiology.

If you closely followed the Ebola outbreak minute by minute, are fascinated by the vaccine controversy, and are riveted by the news updates of flu season each year when the virus is tracked and reported, you may want to look more closely into the field of public health!
