A deadly bird-flu strain first reported among humans two years ago is a swift transformer loaded with more genetic ammunition than previously thought, a mainland study reveals.
Researchers found that much of the virus deadly power came from within, and at least half of its six genes are capable of causing illness in humans.
They also found that H7N9 changed rapidly after finding a new host. In some cases mutations that helped it survive better in mammals appeared in just four days, enabling the virus to spread quickly and inflict more damage inside the new host.
