China's state media report a sixth person in the country has been diagnosed with bird flu, while a new outbreak of the disease has been spotted in a flock of ducks.

The Xinhua news agency says the Health Ministry has identified the latest human victim as a 35-year-old man in Suichuan County in the eastern province of Jiangxi. There were no further details.

Earlier, the Agriculture Ministry reported an outbreak in a flock of ducks, also in Jiangxi province. It is not clear if the two incidents are linked.

The H5N1 strain of bird flu has killed more than 70 people in East Asia since 2003. Scientists fear it could mutate and be passed from human to human.
