Public Health Professionals: What Roles They Take To Secure Health?

by Martha Simmonds

Public health is a scientific career path focusing on improving the health and wellbeing of communities. Public health professionals develop preventive strategies, promote healthy lifestyles and mitigate the spread of infections. They are involved in research and development to launch new vaccines, improve existing treatments and advance diagnostic practices.

The contributions of public health professionals have a community and nation-wide impact. They have the potential and opportunities to grow global healthcare practices and increase healthcare accessibility for marginalized communities.

What is Public Health?

Public health is the science of protecting the health and wellbeing of large populations. These populations could be a specific ethnic community, a small neighborhood, a country, or even an entire continent. Public health professionals, researchers, and epidemiologists identify and prevent healthcare problems from occurring and worsening. They devise educational programs, suggest healthcare policies, and design services based on research-driven practices.

While clinical practitioners like nurses and doctors treat patients, public health workers work to prevent illnesses and propose innovative solutions. They strive to reduce disparities in healthcare accessibility to increase patient care quality and equality for all communities.

Let’s take a closer look at the contributions of public health professionals in promoting health and wellbeing.

Research & Development

Research and development are one of the core areas of expertise in public health. Professionals, certified medical practitioners, health educators, and researchers come together to research, develop and propose healthcare innovations and enhance patient care. Interestingly, the research isn’t solely focused on physical conditions, viruses, and infections.

Public health professionals investigate the causes of adolescent depression, gun violence, mental illnesses, and water pollution, amongst other pressing concerns. They develop interventions and preventive measures to mitigate and lessen the adverse impacts of physical, mental, and environmental health hazards.

There’s a growing demand for public health professions in the government and non-profit sectors. Aspiring public health specialists and researchers can pursue the masters in public health online to expand their opportunities and potential. For instance, a master’s degree will enable you to research the causes of drug trafficking or cancer risks for women.

Disseminating Healthcare Information

Since the beginning of the pandemic, the World Health Organization (WHO) has played a dynamic role in disseminating accurate information. WHO officials have vigorously combatted the spread of false information to maintain clarity about the novel coronavirus and prevent chaos. Public health professionals are responsible for community information regarding diseases, viruses, infections, and health hazards.

Public health professionals disseminate information and raise awareness through multiple platforms and mediums. They engage with communities on a local, national and international level. Public health organizations collaborate with governments, healthcare organizations, and clinical practitioners to spread awareness and accurate information.

Developing Strategies & Healthcare Solutions

Public health contributions and innovations impact large populations and communities. Epidemiologists, bio-technicians, biostatisticians, clinical researchers, and other public health specialists develop innovative healthcare solutions. They study medical illnesses, viruses, and infections to develop vaccines and combat diseases to increase life expectancy and quality.

Public health researchers develop preventive and interventional strategies to curb bullying incidents in school. They can help prevent the spread of certain infections and diseases, such as HIV/AIDS, in specific populations or communities. They can explore the causes of mental health illnesses, such as schizophrenia, and develop preventive measures to reduce increasing onset rates.

Behavioral research scientists explore and propose policies to help patients with autism, learning disabilities, and other disorders. Professionals collaborate to investigate the adverse impact of unhealthy habits, such as smoking. They promote healthy habits to reduce the spread of chronic illnesses and spread awareness regarding risk factors.

Environmental health experts devise solutions to reduce environmental damage and ensure equal access to clean drinking water. Public health workers and community managers develop nutrition programs to ensure a healthy diet for students across public schools. These health specialists also propose safety standards for employee health and wellbeing.

Controlling & Managing Disease Outbreaks

Public health agencies and professionals are dedicated to saving lives and protecting the health of communities and large populations. Disease prevention and managing disease outbreaks are one of the fundamental responsibilities of governmental public health agencies.

For instance, the Centers for Disease Control and Prevention (CDC) is the central public health agency in the United States. The CDC has the following responsibilities:

• Preventing and managing disease and virus outbreaks
• Curbing the causes of chronic illnesses, such as diabetes, cancer, and heart diseases
• Ensuring equal access to safe and clean drinking water
• Curb food shortages and fulfilling nutrition needs
• Proposing preventive measures to curb risk factors

A disease or virus outbreak, much like the coronavirus pandemic, is a grave security threat that requires a robust mitigation response. Public health agencies and professionals utilize world-class expertise and cutting-edge infrastructure to mitigate healthcare crises and protect populations against life-threatening illnesses.

How does the CDC perform this job? The US public health agency employs over 14,000 public health professionals in more than 170 occupations. These public health specialists work across all 50 US states and collaborate with public health agencies across over 50 countries.

They research disease patterns, issue warnings, collaborate with policymakers and implementers, and spread awareness with accurate information. They empower the general public with tools and resources to take responsibility for their health and wellbeing.


Public health professionals make enormous contributions that benefit large communities and healthcare systems worldwide. They make groundbreaking discoveries to innovate existing treatments and preventive regimes to improve life quality and increase life expectancy. Public health is a rewarding field that allows specialists to improve, innovate, invent and improvise.

Professionals work with marginalized and disadvantaged communities to promote healthcare accessibility and quality. In the wake of the coronavirus pandemic, the responsibility for public health professionals has increased tenfold. The global healthcare sector has been overwhelmed in an unprecedented manner, and healthcare leaders seek formidable solutions.

In today’s healthcare industry, public health researchers and epidemiologists drive the efforts to end the pandemic and restore normalcy. They have tirelessly dedicated themselves to the creation of an effective vaccine and mass-administering campaigns. Once the pandemic boils over, the focus will shift towards improving healthcare quality and promoting equality.
