How is bird flu spread among birds and people?
Avian flu gets into the digestive system of birds and is excreted with faeces. Waterfowl seemed to be particularly vulnerable. It is not known exactly how humans pick up the virus from birds but it is assumed to involve very close contact, perhaps by plucking feathers or in the case of children by playing among infected animals. Eating cooked poultry meat or eggs carries no risk.
