yeah this one is real. All flus can and do mutate. The danger is remixing when it gets into swine.
swine can catch many kinds of flu, unlike us. If a pig gets double infected, the viruses can recombine. That's what probably happened here, with three viruses -- one human, one swine, one avian. Because of the human component, we can catch it easily. The other components are foreign to us so they are more dangerous.
