The full name is "severe acute respiratory syndrome coronavirus 2".
It is not mild, nor has it ever been. They don't call it MARS-CoV-2. It would be a very confusing name anyways because we live on Earth, not Mars, btw. And I don't think the Martians would appreciate being unluckily associated with this virus.
turns out they're both incorrect, we actually live on hellworld :covid-cool:
So Mars, but Mars from DOOM
