The Crimson Contagion planning exercise run last year by the Department of Health and Human Services involved officials from 12 states and at least a dozen federal agencies. They included the Pentagon, the Department of Veterans Affairs and the National Security Council. Groups like the American Red Cross and American Nurses Association were invited to join, as were health insurance companies and major hospitals like the Mayo Clinic.

The war game-like exercise was overseen by Robert P. Kadlec, a former Air Force physician who has spent decades focused on biodefense issues. After stints on the Bush administration’s Homeland Security Council and the staff of the Senate Intelligence Committee, he was appointed assistant secretary of Health and Human Services for Preparedness and Response.

During the exercise, CDC recommended that states delay school openings for six weeks, 

This exercise took place entirely out of the public eye but had strangely prescient foretelling of events only 5 months later….. the worst pandemic in 100 years came only a few months after an elaborate multi-agency trial run of the same in which former high officials of the Trump administration participated.
