Following on from my post of yesterday, it seems that WHO really are bowing to political pressure and redefining pandemic to take account of virulence as well as geographical spread. As an academic, Vincent Racaniello, author of the Virology Blog, is typically scathing:

WHO redefining pandemic is absurd. Pandemic is an epidemiological definition that has nothing to do with virulence […] Although pandemic is most frequently associated with influenza virus, other infectious agents may cause worldwide epidemics […] WHO should leave textbook writing to others. To paraphrase Andre Lwoff, a pandemic is a pandemic. The word implies nothing about virulence – and has little to do with politics.

As a fully paid-up pedant (and erstwhile academic) I entirely agree.
