Few are calling it "Chinese Coronavirus." Rather, it's being called the "The Chinese Virus," mainly by the President.
As others mentioned, consider the motivations for doing it, which are to provide political cover for a botched response to it.
Moreover, it's stupid to attach an ethnicity and nationality to a disease. The purpose is to antagonize Chinese people, which does no one any good.
Also consider its impact on people. My wife, for example, is an intensive care physician. She's also Asian. The last thing she needs is to deal with uneducated racists fearing her and/or diminishing her work while she's trying to provide care in an overcrowded unit.
Don't be an asshole.
