The new bird influenza that’s killed six people in eastern China has some of the genetic hallmarks of an easily transmissible virus, according to the scientist who showed how H5N1 avian flu could become airborne.
The H7N9 strain, which is a new virus formed as a result of two others merging their genetic material, has features of viruses that are known to jump easily from birds to mammals, and a mutation that may help it attach to cells in the respiratory tract, said Ron Fouchier, a professor of molecular virology at Erasmus Medical Center in the Netherlands, in a telephone interview yesterday.
