China's official Xinhua news agency says a farmer in the northwest has died from the deadly H5N1 strain of bird flu.

Xinhua says the 62-year-old man, from the Xinjiang region, became ill on June 19 and died on July 12. The agency says research showed the man did not have contact with any humans infected with the virus or with dead poultry in the month before he died.

It says local health authorities found no abnormal symptoms in people with whom the farmer came in contact.

Meanwhile in Indonesia, health officials say a teenager who tested positive for bird flu has refused to stay in the hospital.

The teenager had handled dead chickens at his house, and tests results from two laboratories show he has bird flu.

Forty-four people have died of bird flu in Indonesia, and 14 in China.
