Indonesian health officials say local tests show an eight-year-old boy in Jakarta has died of bird flu.
The child died last week.
A World Health Organization (WHO) laboratory in Hong Kong is testing samples from the boy as well as from a 39-year-old man who was earlier reported to have contracted the disease.
Indonesian health officials announced Friday that local tests showed the man had died earlier in the week of bird flu.
Results from the WHO testing are expected in several days. If the deaths are confirmed to be caused by the bird flu virus, they will bring Indonesia's human toll from the disease to eleven.
So far, avian flu is known to have killed nine people in Indonesia, and more than 70 in Asia since 2003.
