Covid was never named in that 2015 ALICE exercise. it was an exercise to see what would happen if there was a MERS outbreak / pandemic.
just For reference. Naming wise.
An explanation of the official names for the corona virus disease (COVID-2019) and the virus that causes it.
www.who.int
SARS-CoV-2 is the virus. Its a Novel Coronavirus, as in the virus is in the Coronavirusfamily but is new to humans so it was calssed as Novel as no human immunity was expected.
COVID-19 is the disease the virus causes.
They didn't want to call it SARS-19 due to the 2003 SARS outbreak so they named it COVID.
Edit: Sorry I just noticed there had been comments on this alreayd.
