A 10-year-old girl from southern Vietnam has died of bird flu, the 12th human victim from the virus in a month, a health official said Monday.

The girl from Long An province died Sunday night after surviving about a week in critical condition on a respirator, said a doctor from Pediatrics Hospital Number One in Ho Chi Minh City.

Dead chicken were reported at the girl´s house and in her village nearly a month ago, and she developed a high fever and coughing a week after helping her family bury the dead poultry, said Ngo Van Hoang, director of Long An provincial Preventive Medicine Center.

Two men from northern Vietnam, ages 66 and 30, who tested positive for the H5N1 strain of bird flu remained in stable condition Monday but were recovering, state-controlled media reported.

Meanwhile, a Cambodian woman died Saturday at a hospital in southern Vietnam, a doctor at the General Hospital in Kien Giang province, which borders Cambodia, said on condition of anonymity.

She was admitted with bird flu symptoms, but tests were still being conducted to determine whether she was infected with the virus, he said.
