China steps up response to bird flu cases

A second Chinese city culled birds on Saturday to prevent the spread of H7N9 avian influenza, which has killed six people in the country, as Shanghai's live poultry markets remained shut.


China has confirmed 16 cases of the H7N9 strain, the health ministry said, since announcing a week ago that the virus had been found in humans for the first time. The virus, originally located in Shanghai, has apparently spread, and two other fatalities were reported from the neighboring province of Zhejiang, prompting the response. (AFP)
