China says varied strains of bird flu on the rise

Officials in China said at least three strains of bird flu, including H5N1, H7N9, and H5N6, have been detected in various provinces. Some patients are in critical condition, and at least two deaths have been caused. In the country's Sichuan province in southwestern China, a 42-year-old man with pneumonia tested positive for H5N1, according to a report from state-run news agency Xinhua. His symptoms started in late December, and by early January he was experiencing respiratory failure. Officials say he remains in critical condition and was in contact with live poultry before he became ill. Officials said the man's home has been sterilized and at least 58 people who where in contact with the patient are being monitored. So far, they do not exhibit any infections. Officials in Zhejiang said a man died from a different strain of bird flu, H7N9, that first infected people in 2013. Authorities did not release details of the death, but did say at least two other patients, one critical, were infected in Ningbo. Finally, authorities in China's southern Guangdong province said a third infection with H5N6 bird flu occurred with the man in serious condition in a hospital in Shenzhen, which lies just across the border from the international financial center of Hong Kong. This follows an earlier death from H5N6 in Shenzhen in December and officials said another patient was infected in the city of Zhaoqing. Report
