How would we handle an avian flu pandemic?

Concerns have been raised in recent months after an outbreak of avian flu caused by the virus H5N1 was detected in cattle in the US. To date, 139 affected herds have been identified, and four dairy workers have contracted the virus. The UK Health Security Agency, which previously believed there to be minimal risk of the virus evolving into a form which could spread among humans, now believes there is up to a one-in-three chance of it doing so. A factory in Liverpool has been busy manufacturing stockpiles of a ‘pre-pandemic’ vaccine which will be given to farm workers and others in occupations that bring them into close contact with bird flu.

We have been here before with bird flu. An outbreak among birds in East Asia in 2005 led to the World Health Organisation predicting that the disease could go on to kill between two million and 7.4 million people.
