H.R. 4516 — To amend the Public Health Service Act to provide for the inclusion of a biological attribution strategy, and an early warning strategy and implementation plan, in the National Health Security Strategy, and for other purposes.

This bill expands the required components of the National Health Security Strategy (a coordinated strategy among federal, state, and local entities to address public health emergencies). Specifically, the National Health Security Strategy must address (1) coordination of federal efforts related to biological attribution (i.e., determining the source of biological hazards and pathogens of pandemic potential); and (2) early warning of emerging biological, chemical, and radiological threats, including synthetic drugs and fentanyl.
