Now that we have covered how the public health sector is rapidly growing, here are some reasons why it’s in demand.

1. Increasingly Complex Health Challenges

The importance of public health professionals has become more significant in light of the ever-increasingly complex health challenges facing the world, ranging from infectious diseases to chronic illnesses. The necessity for a multidisciplinary approach to these challenges has rendered public health a critical field for addressing health concerns at the population level.

According to WHO (World Health Organization), non-communicable diseases such as diabetes, heart disease, and cancer account for 71% of all global deaths. In addition, the global burden of infectious diseases such as HIV/AIDS, tuberculosis, and malaria continue to pose a significant challenge. As a result, the demand for public health professionals with the knowledge and skills to address these complex health challenges is higher than ever.

2. The COVID-19 Pandemic


The COVID-19 pandemic has catapulted public health to the forefront of global attention. The pandemic has underscored the significance of preparedness, surveillance, and response when facing emerging infectious diseases. Public health professionals have played an instrumental role in addressing the pandemic, ranging from monitoring and restraining the spread of the virus to promoting public health messaging and distributing vaccines.

The COVID-19 pandemic has also shed light on the importance of health equity and the disproportionate impact of the virus on marginalized communities. Public health professionals have been called to address these disparities and ensure everyone can access quality healthcare and preventive measures.

According to the WHO, as of April 2024, there have been over 750 million confirmed cases and 6.8 million deaths worldwide due to COVID-19. The scale and severity of the pandemic have highlighted the vital role that public health plays in protecting and promoting the health and well-being of populations.

3. Technological Advancements

With the progression of technology and the accessibility of big data, public health has undergone rapid evolution, generating novel prospects for professionals to utilize innovative approaches in their field of work. The capacity to employ data to detect health trends and direct interventions has resulted in more productive public health initiatives.

Moreover, telemedicine and mobile health technologies have enabled public health professionals to reach populations in remote or underserved areas, providing access to care and education that was once limited.

The rise of machine learning (ML) and artificial intelligence (AI) has also significantly contributed to public health. These advanced technologies can analyze large amounts of data and provide insights into complex health problems, enabling public health professionals to develop more effective interventions and prevention strategies. Likewise, innovative statistical tools and systems allow public health professionals to gain population data more efficiently and timely.

As technological advancements continue to shape the field of public health, there is a growing need for professionals who possess both the technical and public health expertise to harness the power of these tools to improve population health.

4. Growing Career Opportunities


The escalating demand for public health professionals has rendered it a stable and secure career option. As per the Bureau of Labor Statistics, the employment rate of health educators and community health workers will grow by 12% from 2021 to 2031, much more rapidly than the average for all occupations. Opting for a profession in public health instills gratification by acknowledging that your work directly contributes to enhancing the health and well-being of communities and, ultimately, society.

The diversity of career paths and the ability to specialize in a particular domain or subfield of interest provides flexibility and the potential for career advancement. As a result, public health is an attractive career option for individuals seeking a fulfilling and challenging career that can positively impact society.
