Public health nursing focuses on improving community health by addressing social, economic, and environmental factors that influence well-being. Public health nurses play a vital role in disease prevention, health promotion, and ensuring access to healthcare services, especially for vulnerable populations. They conduct health education campaigns, administer immunizations, and collaborate with organizations to develop policies that enhance community health. By utilizing data-driven approaches, public health nurses identify health trends, respond to emergencies, and advocate for health equity. Their work extends beyond individual care, emphasizing the collective health of populations to create healthier, more resilient communities.
