The World Health Organization has reported another bird flu death in Indonesia, confirming Monday that a five-year-old boy who died last month was infected with the virus.

Officials said the victim died June 16 in East Java province. He was believed to have come into contact with infected chickens.

Scientists have diagnosed more than 120 bird flu fatalities since late 2003. Most of them have been in Asia.

Scientists worry that human-to-human transmission of the virus could spark a global pandemic.

In late June, the WHO said it believed one Indonesian family became infected through such human-to-human transmission.

But health officials say that the specific H5N1 virus strain that killed seven of eight family members died out with its last victim.
