Public health nursing is a critical component of the healthcare system that focuses on promoting and protecting the health of communities and populations. This specialized field of nursing combines clinical nursing skills with a deep understanding of public health principles to address the unique health challenges faced by diverse groups of people [2]. Public health nurses play a vital role in preventing disease, improving access to healthcare, and promoting health equity. In this article, we will explore the field of public health nursing, its history, roles, challenges, and the significant impact it has on the well-being of societies. Public health nursing is a vital and dynamic field within the broader spectrum of healthcare that plays a pivotal role in promoting and safeguarding the health and well-being of communities and populations [3]. Rooted in the principles of preventive care, health education, and community engagement, public health nursing represents a critical link between individuals and the broader public health infrastructure. This profession, often considered the backbone of public health, is at the forefront of addressing pressing health challenges and advocating for policies that enhance the overall health of communities.

Public health nursing is deeply rooted in history, with its origins dating back to the late 19th century when pioneers like Lillian Wald and Florence Nightingale recognized the importance of nursing interventions beyond individual patient care. Their vision laid the foundation for a profession that focuses not only on treating diseases but also on preventing them and addressing the social determinants that impact health outcomes [4]. Over the years, public health nurses have been instrumental in controlling infectious diseases, improving maternal and child health, ensuring access to healthcare services, and responding to emergencies, including pandemics [5]. In this era of ever-evolving healthcare challenges, public health nursing faces new and complex issues, such as the global health threats posed by emerging infectious diseases, the increasing burden of chronic illnesses, healthcare disparities, environmental concerns, and the digital transformation of healthcare delivery. Public health nurses must adapt to these changes while maintaining their commitment to the core principles of equity, community engagement, health promotion, and disease prevention [6].

This introduction aims to provide an overview of the multifaceted role of public health nursing, delving into its historical roots and contemporary challenges. It highlights the critical importance of this profession in ensuring the health and well-being of individuals and communities alike. Furthermore, it underscores the need for public health nurses to continually evolve and innovate in response to the ever-changing landscape of public health [7].

The evolution of public health nursing

The roots of public health nursing can be traced back to the late 19th century when social reformers like Lillian Wald and Mary and Brewster founded the Henry Street Settlement in New York City [8]. They recognized that the health of individuals was closely tied to the conditions in which they lived, and they pioneered the concept of nurses working within communities to address social determinants of health. Their work laid the foundation for the development of public health nursing as a distinct field. The early 20th century saw the establishment of public health nursing associations, the first of which was the National Organization for Public Health Nursing (NOPHN) in 1912. The pioneering efforts of these organizations led to significant advancements in public health nursing education and practice [9].
