Unfortunately, no one is able to accurately predict whether H5N1 will actually trigger a pandemic--and if it does, we have no idea how long it might last or how deadly the virus will be. As a global public health organization, WHO has a responsibility to alert the international community when it appears that the world is moving closer to a pandemic. It may be years before a pandemic hits the world, and it may ultimately be sparked by a virus other than H5N1. While WHO recognizes that openly talking about a pandemic threat may raise concerns worldwide, we would not be fulfilling our public health mandate if we were not to warn the world of this evolving threat.
