Viruses mutate constantly, this is nothing unusual. Daily mutations take place. The normal flu virus continues to mutate and develop into different types of the virus. For this reason, every year a new flu vaccine is developed, the maximum number of actual combat flu variants. The swine flu virus has a high mutation capability. So there is definitely a danger that the virus mutates. If you are simultaneously in the body of a host, two similar viruses, then this mix and create a new mutated virus. Currently, this could happen to the swine flu and avian flu. If a bird has become infected with the swine flu is simultaneously infected with the bird flu pathogen, it can be a mutation.
