Public health nurses are registered nurses who focus on improving community health and well-being. They work in various settings, such as schools, clinics, and community organizations, to provide education, resources, and support. Their primary goal is to prevent illness and promote healthy lifestyles among populations. These nurses often collaborate with other healthcare professionals and organizations, such as the Centers for Disease Control and Prevention (CDC) and local health departments. They conduct health assessments, develop health programs, and advocate for policies that benefit public health. Their work is essential in addressing health disparities and ensuring access to care for underserved communities.
