So far, China has confirmed 14 H7N9 cases -- six in
Shanghai, four in Jiangsu, three in Zhejiang and one in Anhui, in the
first known human infections of the lesser-known strain. Of all, four
died in Shanghai and one died in Zhejiang.
China's Ministry of Agriculture said Thursday the H7N9 avian flu
virus has been detected from pigeon samples collected at a marketplace
in Songjiang District of Shanghai.
After gene sequence analysis, the national avian flu reference
laboratory concluded that the strain of the H7N9 virus found on pigeons
was highly congenetic with those found on persons infected with H7N9
