Why Is Public Health Important?

When people think of the professionals who keep our healthcare system afloat, they often envision doctors, nurses and the other direct patient care specialists we’re all accustomed to seeing during medical visits. But there’s a whole other sector of healthcare that has a critical impact on our day-to-day lives: public health.

According to the Centers for Disease Control and Prevention (CDC), public health is the science of protecting and improving the health of people and their communities. While other health-focused career paths involve the care for and treatment of specific patients, certain demographics or particular conditions, public health is concerned with protecting the health of entire populations.

So, why is public health important? Read on as we explore the far-reaching effects public health professionals have on our everyday lives

What is public health?

In contrast to physicians who focus primarily on treating individuals who become sick or injured, public health professionals concentrate their efforts on promoting healthy lifestyles, researching disease and injury prevention, and detecting, preventing and responding to infectious diseases. In practice, this can take on many forms, including implementing educational programs, recommending policies or organizing vaccine clinics.

With a focus on community-wide prevention, public health professionals may work with populations as small as a local neighborhood or as large as an entire region of the world. By doing things like helping to establish workplace safety standards, ensuring schools provide kids with access to healthy meals, tracking disease outbreaks and shedding light on why some people are more likely to suffer from poor health than others, public health professionals have a much greater impact than many realize

Why is public health important?

Because so much of the work takes place behind the scenes, it can seem like public health is a relatively small component of our healthcare system at large. But the core functions of public health have proven to be critical in helping that system function effectively. By focusing on community-wide prevention and overall health, public health saves our communities money, improves our quality of life, helps children thrive and reduces human suffering.

The CDC highlights the core function of public health as an effort to achieve equity within our communities. This is enacted by actively promoting policies, systems and overall community conditions that enable optimal health for all, while also working to remove systemic barriers that have resulted in health inequities — things like poverty, racism, gender discrimination and ableism.

To further demonstrate this far-reaching impact in practice, the CDC has outlined the following 10 Essential Public Health Services as a framework for carrying out the mission of public health:

  • Assess and monitor population health status factors that influence health and community needs
  • Investigate, diagnose and address health problems and hazards affecting the population
  • Communicate effectively to inform and educate people about health, factors that influence it and how to improve it
  • Strengthen, support and mobilize communities and partnerships to improve health
  • Create, champion and implement policies, plans and laws that impact health
  • Utilize legal and regulatory actions designed to improve and protect the public’s health
  • Ensure an effective system that enables equitable access to the individual services and care needed to be healthy
  • Build and support a diverse and skilled public health workforce
  • Improve and innovate public health functions with ongoing evaluation, research and continuous quality improvement
  • Build and maintain a strong organizational infrastructure for public health


Why work in public health?

Working in this field can lead to a unique health-centric career path because effective public health efforts are dependent on both a professional’s business skills and their knowledge of population health. Public health professionals have the ability to make a tangible difference in the lives of numerous people, but in order to do so, they must maintain a multifaceted skill set.
