Medicine & TechnologyIn the wake of the Ebola pandemic, researchers in China have identified a virus capable of global infection that has been mutating and brewing on the sidelines. A strain of the avian influenza, the H7N9 flu emerged in eastern China in Feb. 2013 in a small population with a mortality rate of roughly 33%. But over the last year, since it reemerged in October 2013, the virus has been spreading steadily, and mutating along the way. Now public health officials fear that the growing viral infection may soon reach the levels much like the Ebola outbreak, and it is something that researchers are heavily investigating.
