China reports 5th death from H7N9 bird flu

Authorities in Shanghai said Thursday night that another person has died from H7N9 bird flu, bringing the death toll from the new deadly strain to five around the country.

The city has reported six infections 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 strain on Thursday. The commission gave no further information on the latest case.

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 transporter from Rugao in neighboring Jiangsu Province.

He developed symptoms 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 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 virus.

The ministry has ordered beefed-up monitoring of H7N9 bird flu virus in more areas.

China's health authorities have promised transparency and cooperation to the World Health Organization in regards to human infections of the new strain of bird flu.

The Chinese Center for Disease Control and Prevention said Wednesday that no human-to-human transmission of H7N9 has been discovered and no epidemiological connection between these cases has been found.
