Corona viruses are nothing new. They are among the most common respiratory viruses in the world. Have you ever had a cold? Good chance it was a corona virus. Is this one coming out of China one of the more serious ones? Maybe. Maybe not. The "we're all gonna die" reaction is about as valid as all the other "we're all gonna die" scares we've had. Will people die? Sure. A lot of people? Probably not.
