"SHANGHAI has ordered all live poultry markets in the city closed after culling more than 20,000 birds to curb the spread of the H7N9 flu virus, which has killed six people in China. The latest fatality was a 64-year-old farmer who died in Huzhou. He is thought to be among 14 previously confirmed human cases of H7N9, and is the second person from Zhejiang province to die from the new bird flu strain, with the other four fatalities in Shanghai. The moves came after the virus was found in pigeon samples from the Huhuai market in Shanghai, where Xinhua said a total of 20,536 chickens, ducks, geese and pigeons had been slaughtered."
"Live poultry markets are being shuttered temporarily for public safety, and all trade in live poultry banned."
This virus could be more dangerous then H5N1 Bird Flu, because it's often not detected in birds before it's passed on to humans.
