Rome - The multi-billion-dollar trade in poultry and wild birds, especially illegal trading, may have helped spread deadly bird flu around the world, leading bird flu experts said on Tuesday.
The virus has killed 127 of the 224 people it has infected since re-emerging in Asia in late 2003, according to the World Health Organisation (WHO).
As the deadly H5N1 virus spread rapidly in the past six months from Asia into parts of the Middle East, Europe and Africa, specialists have been working out how it travels.
"In this outbreak of H5N1, it's a combination - there is no doubt that the wild birds play their role (in spreading the virus), but so do humans," Robert Webster, a leading avian flu expert, told reporters.

"People acknowledge that probably the most important spreader of influenza overall is the human and the globalisation of trade," Webster, professor at St Jude Children's Research Hospital in the United States, said on the sidelines of a bird flu conference in Rome, organised by the Food and Agriculture Organisation (FAO) and World Animal Health Organisation (OIE).
He said there was evidence that migrating wild birds helped to spread bird flu to Mongolia from China last year and in general contributed to the spread of the virus from Asia to Europe, the Middle Asia and Africa.
But he said experts should also look carefully into the trading of poultry, both live and frozen, and compare trade maps with the geography of the virus.
