China Announces 4 New Bird Flu Cases

SHANGHAI — China said Tuesday that four more people in the coastal part of the country have been infected with a new strain of bird flu, which is believed to have killed two Shanghai residents last month and left one person in critical condition.

The officials said laboratory tests had confirmed that all four were infected with a strain of bird flu identified as H7N9, which was not found in humans before the Shanghai cases. The cases are troubling because there is no vaccine for the H7N9 strain and because another strain of bird flu, identified as H5N1, killed hundreds of people in Asia beginning in 2003, and led to the deaths of tens of millions of birds. The World Health Organization says that most H5N1 cases had involved contact with infected poultry. One of the four people on Nanjing infected with the H7N9 virus is a poultry butcher. Health authorities had previously reported that H7N9 cannot easily be contracted by humans, and officials said that no one who had contact with the four infected patients had developed symptoms. The agency said it was told about the three Shanghai cases by Chinese health authorities on Sunday. The two who died there were men aged 27 and 87; the critically ill patient there is a 35-year-old woman from neighboring Anhui Province. In Nanjing, the authorities said late Tuesday that all four infected individuals there were from Jiangsu Province: one each from the cities of Nanjing, Suzhou and Wuxi and one from Shuyang County. One is male and three are female, they said; two of them began to develop flu symptoms on March 19. The government said in Shanghai on Monday that no link was found between the bird flu virus and the 15,000 dead pigs that have been found recently in the Huangpu River. City officials have not yet explained how or why the pig carcasses wound up in the river, though the government said one pig farmer had admitted dumping some dead pigs there.

Twitter List: Reporters and Editors The authorities said the two Shanghai men, 27 and 87 years old, fell ill after contracting the H7N9 strain in February and died in March. A third person, a 35-year-old woman from the city of Chuzhou, in neighboring Anhui Province, also contracted the strain and is critically ill. China’s National Health and Family Planning Commission said it was unclear how the three had been infected. The commission said in a statement that all three showed initial symptoms of coughing and fever, which later developed into pneumonia and difficulty breathing. The health authorities said tests identified the H7N9 strain in the three victims. The government said that the three had not had mutual contact and that dozens of people who had contact with them did not appear to have been affected. The H7N9 strain of avian or bird flu, had not been previously found in humans. The Chinese Center for Disease Control and Prevention confirmed that the strain was present on Saturday, the health commission said. The commission said the strain was not believed to be highly contagious among humans. Another strain of avian flu, H5N1, has led to hundreds of deaths since 2003 and has killed millions of birds.
