The deadly H5N1 strain of bird flu has killed a 31-year-old man, the second death reported in south-west China.
The Guizhou provincial health department said on its website that the man died of multiple organ failure yesterday at a hospital in the city of Guiyang.
The man was the second of two people to have died in Guiyang after contracting bird flu early this month. The first fatality was a 21-year-old woman.
The official Xinhua News Agency says both patients had close contacts with birds.
Xinhua says 110 people who had contact with the patients have been released from quarantine.
Most bird flu cases in humans come from close contact with infected poultry.
Epidemiologists fear the virus might eventually mutate into a form that is highly contagious among people.
