"The 2019-2022 NHSS [National Health Security Strategy] is focused on three overarching objectives. As health security threats continue to emerge and evolve, these objectives are intended to be flexible and adaptable. 1. Prepare, mobilize, and coordinate the Whole-of-Government to bring the full spectrum of federal medical and public health capabilities to support SLTT [state, local, tribal, and territorial] authorities in the event of a public health emergency, disaster, or attack. [...] 2. Protect the nation from the health effects of emerging and pandemic infectious diseases and chemical, biological, radiological, and nuclear (CBRN) threats. [...] 3. Leverage the capabilities of the private sector."
