I read someone else say that Covid-19 was "an apocalypse" and would "decimate" the American people.
Come on! Those don't overlap.
Well. In Italy it DID decimate. Technically.
Seriously, I'd be very reluctant to call it an apocalypse. That means total, final destruction. Even if the worse case happens, it's not "an apocalypse". Probably the most descriptive adjective to describe our situation is pandemic.
