Bird flu mutating in southern China, pandemic threatens: Shanghaiist

The deadly strain of the bird flu virus H7N9, which first infected humans in Shanghai during 2013, is entrenched in flocks of chickens and ducks in the south of China and mutating, posing an even greater threat to humanity, according to the largest-ever genomic survey of the virus.

In an article for Nature, author Guan Yi and colleagues at the University of Hong Kong warn that unless drastic measures are taken to eradicate the virus, it will continue to mutate. “H7N9 viruses have spread from eastern to southern China and become persistent in chickens,” they wrote. Given that the virus can infect humans, it “should be considered as a major candidate to emerge as a pandemic strain.”
