I don't think you follow the news there. Just because you've only heard it yesterday doesn't make it new. The neighbouring countries have been on guard on the issue. There have been lots of news, leaks and complaints on this issue for the past several weeks. In fact the wet market in Wuhan had been officially "closed" for at least 3 weeks due to the disease. That means the pandemic has been spreading far longer than that.
Now they suddenly started to release updated numbers (due to pressure from their neighbouring countries) and you think it'd only "escalated in a week".
