The World Health Organization is warning of the danger of small, undetected bird flu outbreaks in China, following the country's third confirmed human fatality from the virus.
China announced on Thursday the latest bird flu victim was a 41-year-old woman in Fujian province who had died last week. No outbreaks were reported in the area where she lived, and authorities are unsure how she contracted the virus.
The WHO's spokesman in Beijing, Roy Wadia, said Friday many bird flu outbreaks among wild birds and poultry in China are small and hard to detect.
He said it is hard for China to alert the public when infected birds die in small numbers.Some information for this report was provided by AFP and Reuters.
