This bill, known as the "Public Health Improvement Act," aims to significantly restructure the Centers for Disease Control and Prevention and redefine the scope of federal public health authority. It establishes a 12-year term limit for both the Director of the CDC and the Director of the National Institutes of Health. Furthermore, the legislation narrows the CDC's strategic plan by removing its focus on non-communicable diseases, injuries, and occupational and environmental hazards, concentrating its mission primarily on communicable diseases . The bill also reforms the appointment process for the CDC Director's advisory committee, granting more influence to congressional leaders and the Comptroller General. It restricts the Department of Health and Human Services' regulatory power concerning communicable diseases to specific actions like inspection and disinfection, rather than broader interventions. Crucially, the legislation mandates congressional approval by a majority vote in both chambers for the renewal of public health emergency declarations, limiting their duration. Finally, it transfers several major CDC centers, including those for chronic disease prevention, environmental health, and injury prevention, to the National Institutes of Health, and includes a preemption clause for its provisions.
