I agree. The Chinese went hysterical when the outbreak was first noticed, and I heard a lot about it spontaneously when wishing people happy new year. Hysteria continued right up to the point where... everyone went back to work.
I think the government got unlucky that the outbreak coincided with a major holiday. And while shutting things down was a good idea in many ways, it also meant that people were stuck at home with nothing to do but freak out. So that's what everybody did.
