The World Health Organisation said a Chinese woman became the first human to die from a rare bird flu strain in humans, but the strain did not appear to have spread among the population.
The organisation said in a statement late on Tuesday that the 56-year-old woman from Guangdong Province is the third known case of H3N8 influenza, a subtype of bird flu.
The other two cases were also in China and were recorded last year.
The Guangdong Provincial Centre for Disease Control and Prevention announced the third case late last month, but gave no details about the woman’s death.
The health organisation said the woman was suffering from several diseases and had frequent contact with live birds.
