Why is this new H1N1 virus sometimes called “swine flu”?
This virus was originally referred to as “swine flu” because laboratory testing showed that many of the genes in this new virus were very similar to influenza viruses that normally occur in pigs in North America. But further study has shown that this new virus is very different from what normally circulates in North American pigs. It has two genes from flu viruses that normally circulate in pigs in Europe and Asia and avian genes and human genes. Scientists call this a “quadruple reassortant” virus.

Where did this virus get these genes?? from just people right ? no these genes are from a pig,human and avian which is from CLOSE contact with affected animals. Just as the video tells you animals gave humans the virus because of the way the animal/meat was taken care of. Heavy world travel spreds the virus thoughout the world and can't die out like they used to many years ago which can create a "super virus" like aids.
