 BBC - Health - Conditions - Bird flu
The appearance in humans of a type of flu which normally only affects birds may be an important sign that some strains of the virus are changing in a way that could threaten people around the globe.
One of the most worrying features of the viruses which cause flu is the way that they are continually changing over time, through small changes in their make-up called antigenic drift and occasional abrupt major changes called antigenic shift.
New strains of flu tend to emerge in Asia and the East, where people live in closer quarters with their animals and different flu viruses may mix to cause new strains, or pass between species.
