Thanks.
Fair enough, there have been other recent simulations.They didn't come up on my first page Google but they are very interesting. This is how Wiki describes the Crimson Contagion:
Crimson Contagion was a joint exercise conducted from January to August 2019, in which numerous national, state and local, private and public organizations in the US participated, in order to test the capacity of the federal government and twelve states to respond to a severe pandemic of
influenza originating in
China.
The
simulation, which was conducted months prior to the start of the
COVID-19 pandemic, involves a scenario in which tourists returning from China spread a respiratory
virus in the United States, beginning in
Chicago. In less than two months the virus had infected 110 million Americans, killing more than half a million.
