BEIJING — A Chinese woman has died from bird flu in a Beijing hospital, the government reported today, but the World Health Organization said the case did not appear to signal a new public health threat.

China’s Ministry of Health said Huang Yanqing, 19, died Monday and tests confirmed she had the H5N1 bird flu virus. The official Xinhua News Agency said Huang became ill after buying and cleaning nine ducks in December at a market in Hebei province, which borders Beijing.
