The pig flu pandemic is evil and will be the end of the world.
WHO said no such thing in any of those incidents. Only the voices in your head are saying this. WHO has simply said that it is a public health emergency of international concern with the potential for a pandemic. Cases have now been reported in several countries, and it has killed some young, otherwise healthy people so it is a no brainer that it bears watching, and giving public health officials around the world a heads up is a reasonable precaution. No one has said you need to be quarantined, take anti-virals, or be vaccinated. All they've said so far is "Hey, if you are a health care provider keep an eye out for this."
I despair for my species since so many of us seem incapable of rationally responding to mild, reasonably stated warnings. We seem to dismiss them out of hand, or exaggerate them into "OMG, it's the end of the world as we know it.".
