The Importance of a Public Health Worker in a Growing Community

As our communities continue to expand and evolve, the role of public health workers has become increasingly critical. The COVID-19 pandemic has underscored the essential role of public health workers.

These individuals are the unsung heroes working tirelessly behind the scenes to promote and safeguard the health of our communities. From conducting disease surveillance and investigating outbreaks to providing health education and promoting healthy lifestyles, they play a fundamental role in ensuring access to quality healthcare for all.

According to recent statistics, there are currently 86,000 CHWs in the United States. Moreover, the U.S. Bureau of Labor Statistics predicts that the demand for CHWs will continue to increase in the coming years, with a projected growth rate of 15% by 2029.

In this article, we will explore the importance of public health workers in growing communities and their contribution to promoting healthy living.

1. Disease Prevention and Control

Public health workers are responsible for helping prevent the spread of diseases in communities. They conduct disease surveillance and investigate outbreaks to identify potential sources of infection and develop strategies for preventing further spread.

They also work to educate the public about ways to stay healthy and prevent the transmission of diseases. For example, they work to promote vaccination, improve sanitation, and control the spread of infectious diseases. Their efforts have contributed significantly to reducing morbidity and mortality rates in communities.

However, to become an effective public health worker, individuals often need a Master of Public Health (MPH) degree from an accredited program. An MPH degree provides a comprehensive education in public health, including epidemiology, biostatistics, health policy, and environmental health. Fortunately, there are many accredited MPH online programs available that offer flexible schedules and high-quality education. These programs can help individuals achieve their career goals while balancing other commitments, such as work and family.

2. Health Promotion and Education

Public health workers play an essential role in promoting healthy lifestyles and educating communities on health-related issues. They collaborate with organizations, such as schools, community centers, and hospitals, to teach people about the importance of exercise, nutrition, and healthy behaviors.

One of the primary ways public health workers promote health education is by developing and implementing programs that encourage healthy living. For example, they may design and lead fitness classes, cooking workshops, and nutrition seminars to educate individuals on the importance of healthy eating and physical activity. They also work with schools and other community organizations to develop health education curriculums that teach children and adolescents about healthy behaviors.

In addition to promoting healthy behaviors, public health workers also educate communities on specific health-related issues. For example, during the COVID-19 pandemic, public health workers played a crucial role in educating individuals on protection. They provided information on mask-wearing, social distancing, and other safety measures to help prevent the spread of the disease.

3. Response to Public Health Emergencies

Public health emergencies such as pandemics, bioterrorism, and natural disasters require a swift and coordinated response to contain the spread of diseases, ensure access to medical care, and provide support to affected communities. Public health workers assist in responding to these emergencies.

They set up temporary medical facilities, distribute supplies, and work with healthcare professionals and emergency responders to ensure everyone receives necessary medical care. Their efforts are essential to preventing the spread of diseases and keeping our communities safe and healthy.

For instance, during the COVID-19 pandemic, public health workers were at the front of the response effort. They worked tirelessly to provide testing, contact tracing, and vaccination services. They collaborated with healthcare professionals, community organizations, and government agencies to develop and implement strategies to slow the spread of the virus.

4. Health Equity and Social Justice

Public health workers promote health equity and social justice in communities. Health equity means fair opportunity for everyone to achieve good health regardless of background, social or economic status, race, ethnicity, gender, or age. Social justice, on the other hand, gives everyone access to the same opportunities, rights, and resources, regardless of their identity.

Public health workers recognize that social determinants of health have a significant impact on an individual’s well-being, in addition to personal choices. Social determinants of health are the social and economic factors that shape an individual’s health outcomes. These factors include access to healthy food options, safe housing, and quality healthcare services, as well as socioeconomic status, race, and other social and environmental factors. For example, people living in poverty may have limited access to healthy food options or safe housing, which can negatively impact their health.

Public health workers work to address these social determinants of health by advocating for policies that promote health equity and social justice. They work to ensure that all individuals have access to quality healthcare services, regardless of their socioeconomic status. For example, they may work to develop programs that provide free or low-cost healthcare services to underserved communities.

5. Mental Health Advocate

As communities grow and change, mental health concerns can become more prevalent and complex, making the role of public health workers even more indispensable. According to the World Health Organization, one in four people worldwide will experience a mental health issue at some point in their lifespan.

The COVID-19 pandemic has highlighted the importance of mental health support in growing communities. The pandemic has caused significant stress and anxiety for many individuals, including job loss, financial strain, social isolation, and uncertainty about the future. Public health workers have been instrumental in providing mental health support and resources during the pandemic, including teletherapy and virtual support groups.

Public health workers advocate for promoting mental health and well-being in growing communities. They work to increase access to mental health care services, including counseling, therapy, and medication. They also provide education and awareness campaigns to reduce the stigma surrounding mental health concerns and encourage individuals to seek help when needed.

In addition, they address social determinants of mental health, such as poverty, discrimination, and social isolation. These factors can contribute to poor mental health outcomes and disproportionately impact marginalized communities. Public health workers work to address these issues by promoting policies and programs that address social determinants of health and promote health equity.


As we continue to face new and emerging health challenges, such as the COVID-19 pandemic and the growing burden of chronic diseases, the importance of public health workers becomes even more evident. We must continue to support their efforts and invest in public health infrastructure to ensure that communities have access to the resources and expertise needed to address public health challenges.

Public health workers are the backbone of a healthy community, and their contributions cannot be overstated. By supporting public health workers and investing in public health infrastructure, we can ensure that our communities are prepared to face any health challenge that may arise.
