I'm not saying it's no big deal at all. I fully expect major epidemic proportions here, but 50m is a bit of scare mongering surely. If China has limited it to 90000 by shutting down as you say and we are saying 50m, then surely we should be in the process of shutting down too. Problem is so many mixed messages, world's ending, everyone should go about their normal business etc.
For a whole load of people, the doom laden message does nothing but burden them with anxiety. Let's get real. If it's that bad do something more than flippantly tell us to wash our hands to the National anthem.
