Beijing Brambling, Zhejiang Duck Spawn Deadly Flu, Study Finds
A brambling from Beijing, a wild bird from Korea and a duck from China’s Zhejiang province probably helped spawn the new flu variant that’s killed 10 people, a study in the New England Journal of Medicine found.
The birds were infected with avian flu strains that most resemble the H7N9 virus circulating in eastern China, according to yesterday’s study by researchers at the Chinese Center for Disease Control and Prevention in Beijing and Fudan University in Shanghai.
Thirty-eight people have been sickened with H7N9 flu, which the authors said causes brain damage, muscles to break down and vital organs to fail in its most extreme form. Different mutations in samples taken from patients suggest the virus entered human populations at least twice, the study found.
“We are concerned by the sudden emergence of these infections and the potential threat to the human population,” Rongbao Gao and colleagues wrote. “An understanding of the source and mode of transmission of these infections, further surveillance, and appropriate counter measures are urgently required.” The new strain, which hasn’t been detected in humans or animals before, raises “many urgent questions and global public health concerns,” Timothy Uyeki and Nancy Cox, flu scientists at the Centers for Disease Control and Prevention in Atlanta, said in an accompanying editorial in the journal.
