More than 100 people who had close contact with a bird-flu infected patient in south China's Guangxi Zhuang Autonomous Region have been released from medical observation, the local health department reported yesterday.

The bird flu  has been prevented spreading to other people, said Tan Mingjie, deputy head of the regional health bureau.

On November 23, a 10-year-old girl surnamed Tang from Baiyangping Village of Liangshui Township, Ziyuan County, developed fever and pneumonia. She tested positive for the H5N1 virus.

Now she is undergoing treatment and recovering.

The 100-plus people in the region are in good condition and have been dismissed from medical observation, said Tan.
