A nine-year-old boy surnamed He, who had been formerly diagnosed of "pneumonia of unknown cause," was discharged from hospital on Saturday after being completely cured.
After 25 days of treatment and quarantine in the Hunan Provincial Children's Hospital, the boy whose sister died of severe pneumonia on Oct. 17 was discharged from hospital in central China's Hunan Province.
The boy and his sister aged 12 showed pneumonia symptoms after eating chickens, which died after the highly pathogenic bird flu of H5N1 hit the village of Wantang in Xiangtan County.
Experts have diagnosed the boy's illness as "pneumonia of unknown cause", but did not rule out a possible human case of H5N1 bird flu.
The boy was in bad condition with pathological changes detected on his lungs when he was brought to hospital. His condition began to recover three days later, and a group consultation by doctors on Nov. 7 decided to stop using hormonal medicine for his disease.
The Chinese Center for Disease Control and Prevention is carrying out further tests on the boy's blood sample, according to doctors with the local hospital.
A team of experts from the World Health Organization (WHO) will come to Hunan next week to work with Chinese doctors to probe three possible human cases of bird flu in China. The boy will be one of the research objects.
The experts will conduct a retrospective investigation of the occurrence and treatment of the three pneumonia cases with unknown causes.
