Pandemics: A Security Risk?
At present a human influenza pandemic is little more than a theoretical possibility. However, and due to the spread of the avian influenza and the fact that there have been cases of bird-to-human transmission, the WHO has issued a pandemic alert to the effect that a new influenza virus subtype is causing disease in human beings but is not yet spreading efficiently and sustainably among the human population. This suggests that the time is ripe for adopting some preparatory action with a view to minimising the damage that could be caused by a pandemic. This analysis assesses the current situation with regard to a possible pandemic caused by the H5N1 virus responsible for avian influenza.
