The main purpose of this legislation, known as the Public Health Nursing Act, is to strengthen the public health nursing workforce in the United States. It aims to ensure that there are enough qualified public health nurses to address health issues, especially in underserved communities. The Act requires the Secretary of Health and Human Services to implement activities that will help establish, expand, and sustain this workforce. Key provisions of the Act include the establishment of grant programs for state, local, and territorial public health departments.
