Coronavirus isn't descriptive. SARS-CoV-2 is unbearably clunky. Covid refers to the disease caused by the virus (it's short for "coronavirus disease"); people don't communicate a disease, they communicate a virus. This is like the HIV/AIDS distinction: you can't "catch AIDS". Hence my terminology. Talk about petty, though. It's from wuhan, so calling it "wuhan coronavirus" or "chinese coronavirus" strikes me as more than reasonable.
