It's an ill wind......

摘要

It was bound to happen sooner or later - a mutated flu virus to which there is no human immunity that quickly becomes a pandemic.rnThat the virus has rapidly infected a population living in close proximity with less than ideal sanitary conditions is no surprise, and the speed and extent of its geographical spread was perhaps also to be expected in today's world of highspeed global travel.rnIt could have been worse: the virus might have been a more deadly strain such as H5N1; it might not have been susceptible to existing antiviral drugs; the outbreak might have happened in the depths of a Northern Hemisphere winter when stockpiles are at their lowest; it might have gone unnoticed for longer.
