State media in China report a man has died of bird flu a week after being admitted to hospital with a fever in the southern province of Guangdong.
The bus driver, who lived in Shenzhen, just across the border from Hong Kong, developed symptoms on 21 December and was admitted to a hospital on 25 December with severe pneumonia.
He died in the early afternoon, having tested positive for the H5N1 virus.
Hong Kong culled 17,000 chickens at a poultry market about 10 days ago and suspended all imports of live chickens from mainland China for 21 days after three birds were found to have died from the H5N1 bird flu virus.
The World Health Organization says bird flu has killed 332 people since 2003.
The BBC reports the H5N1 bird flu strain has a high level of mortality, killing up to 60% of humans infected with it.
