Authorities in Shanghai said Thursday night that another person has died from H7N9 bird flu, bringing the death toll to five around the country. The city has reported six infections (感染) to date, and four have died, said the Shanghai Municipal Health and Family Planning Commission. Of the rest two, there was a four-year-old, the agency said. The baby was recovering from mild illness, it added. The person died at Huashan Hospital on Wednesday and was confirmed infected with the H7N9 bird flu on Thursday.

Also on Thursday, the commission reported the city's third death from the H7N9 bird flu. The case involved a 48-year-old man surnamed Chu, a poultry (家禽) transporter from Rugao in neighboring Jiangsu Province. He developed symptoms(症状) of cough on March 28. After having a fever on Monday, he went to a private clinic for treatment. The man then sought help in the Tongji Hospital in Shanghai in the early hours of Wednesday after his condition worsened. Chu died three hours after being admitted to the hospital. He was confirmed infected with the H7N9 virus on Thursday. Eight people who had close contact with him have shown no abnormal symptoms.

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 type of bird flu. 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 (鸽子) samples collected at a marketplace in Songjiang District of Shanghai.

After gene sequence analysis, the national avian flu reference laboratory concluded that the H7N9 virus found on pigeons was highly congenetic with those found on persons infected with H7N9 virus. China's health authorities have promised transparency(透明) and cooperation (合作) to the World Health Organization in regards to human infections of the new type of bird flu. The Chinese Center for Disease Control and Prevention said Wednesday that no human-to-human transmission of H7N9 has been discovered.
