Bird flu virus continues to mutate. If it would be able to transmit from human to human than humanity would face a new pandemic.
In spite of the fact that bird flu is the disease of birds, some viruses of bird flu may infect humans and cause severe infections that often end up with death.
Today bird flu virus is not transmitted from human to human. However, if the virus mutates, it may begin to transmit from human to human which may result in a pandemic.
Scientists claim that only several mutations do separate humans from a real pandemic.
