The governmant can't win in a situation like this. If they react quickly and on a large scale then they contain a dangerous situation, so there is no 'pandemic' and then get accused of over reacting and wasting money. If they fail to contain it and thousands catch it, and lots of people die, then they should have done more.
While I agree the risk to the public is remote, if this sort of thing isn't brought to the public awareness then people will just assume they have a cold, spread it around, and then by the time everyone is aware you have potentially hundreds of cases and a very hard job to contain it.
If it is highly contaigous then it should be treated as such, something like this gets loose in a hospital? Not good.
I remember a few years ago, 1 person at work caught the Norovirus (stomach bug). Within a week a third of the company was off sick with it. Thats in a population of about 400 at the time. Now even if that had a mortaility rate of 1% (it's non leathal) then chances are 1 or 2 people would have died from that 1 index case.
Yes the media overplay these things (they overplay EVERYTHING), but it should be taken seriously.
