The Public Health Service Act is a U.S. law that provides the framework for public health programs and services. It was first enacted in 1944 and has been amended several times to address various health issues. The Act empowers the Department of Health and Human Services to promote and protect the health of the American public through research, disease prevention, and health education. This legislation also establishes funding for health initiatives and supports the work of agencies like the Centers for Disease Control and Prevention (CDC) and the National Institutes of Health (NIH). By facilitating collaboration among federal, state, and local health agencies, the Act aims to improve overall public health outcomes.
