I know what you mean! Covid-19 is more correct as a description than corona, though, since covid is just one virus in the coronavirus family (SARS is another). So coronavirus is the "parent", if you like, and the likes of SARS and Covid-19 are what one actually catches and, hopefully doesn’t, dies from.
Unfortunately, as we move forward and these things inevitably occur again, they will probably be given the same name, designated again by the year they are discovered, so Covid-21, Covid-36, etc, etc...!
Gosh, I hope I’m wrong...
