Hariadi Wibisono, a senior official with the Ministry of Health, said in telephone that the girl's 15-year old sister and three- year old brother also had been suspected of developing the bird flu symptoms. They are now being treated at a hospital in West Java province.

"The local test was positive. There are reported poultry deaths around their residence," said Wibisono, a director charged with eradicating animal-borne diseases.

The World Health Organization has confirmed 12 deaths of bird flu in Indonesia.

Five more patients were also tested positive of bid flu.
