The European Commission says it plans to contribute $100 million in aid to help countries prevent the spread of bird flu.

EU External Relations Commissioner Benita Ferrero-Walder said Friday in Brussels the aid will be offered at next week's bird flu conference in Beijing. She noted that never before has an animal disease posed such a global threat.

Thursday, the World Bank said it had approved $500 million in aid to help fight bird flu.

The World Health Organization says samples of the deadly H5N1 strain taken from two bird flu victims in Turkey show a slight genetic change in the virus - a sign it may be mutating into a human flu virus that could kill millions.

Bird flu has killed three people in Turkey and 79 in East Asia since 2003.
