Seems like a whole lot of fuss over relatively little so far outside of China.
No doubt it is spreading and will continue to do so, with potentially disastrous results. So governments are correct to respond now and try to contain it and slow down its spread. As for members of the public panic buying and the tabloids and their coverage, lets just say I don't have time for any of that nonsense yet. Sure its best for us to take reasonable precautions but realistically there is absolutely no need to panic over anything yet. We simply have to wait and see how it progresses and go from there. There are no truly reliable figures and we all know statistics can be spun in any way that suits the person stating them anyway.
In any case, panicking will not prevent its spread or help anyone if and when it reaches the levels the authorities claim it may do later in the year.
