I didn't mean to say that humans had never been infected by a coronavirus. But this strain is new. After you get a particular strain of the flu you will have some immunity to similar strains. So the world could be starting out with zero immunity.
A given strain of the flu won't infect half the population in the course of a year or two. But in a plausible bad case scenario this coronavirus could.
