Corona virus is just a family of viruses. This one is new and without any treatment. There have been outbreaks in the past. But like I said. Corona virus is a family of viruses, they are not all the exact same. This one is a new type.
It is not the same virus as SARS or MER, the only reason they use "Novel Corona Virus" is because its just a way to refer to a new virus that hasn't been given a specific name. It's of the same family, but not the same virus.
