"Coronavirus" in the general name of a virus that has crown-like spikes on its surface. "Covid19" is the new type of Coronavirus that is currently spreading. Although "Coronavirus" and "Covid19" have different meanings, recently, people have been using "Coronavirus" to mean "Covid19". To correctly use each term, use "Coronavirus" to refer to the general virus with crown-like spikes on it, and "Covid19" to refer to the specific type of Coronavirus that is currently spreading.
