Per Politico:
"The Obama White House National Security Council left the Trump Administration a detailed document on how to respond to a pandemic. The document, whose existence was publicly revealed by Politico in March, was called the "Playbook for Early Response to High-Consequence Emerging Infectious Disease Threats and Biological Incidents".
The playbook - 40 pages plus appendices - contained step-by-step advice on questions to ask, decisions to make, and which federal agencies were responsible for what. It included sample documents that officials could use for inter-agency meetings. And it explicitly listed novel coronaviruses as one of the kinds of pathogens that could require a major response.
The color-coded, checklist-style document addressed issues such as testing, funding, personal protective equipment, emergency declarations, border control measures, diplomacy, the use of the military, public communications, even mortuary services."

By all accounts, this "playbook", with its advanced warnings and suggestions, went completely ignored by the Trump Administration.
