Swine Flu in China Triggers Fears of New Pandemic

A strain of flu virus spreading in Chinese pigs has shown it can also infect humans, suggesting that another pathogen with pandemic potential waits in the wings behind the coronavirus.

The flu strain that jumped to humans has become predominant among pigs across China since 2016, according to a team of researchers that includes George Gao Fu, head of China’s Center for Disease Control and Prevention. The researchers based their findings on surveillance studies conducted in 10 provinces from 2011 through 2018.
