The numbers provided by the WHO no doubt represent a serious undercount, but they do give us an indication of the inexorable global spread of the virus.

GENEVA, July 24 (Reuters) - H1N1 pandemic flu has spread to some 160 countries and killed about 800 people, and needs to be watched carefully in case it mutates and becomes more severe in winter, the World Health Organisation said on Friday.
