According to CDC.gov website, 2009 H1N1 also known as hog flu, and pig flu is a new influenza virus causing illness in people.
Why was it labelled 'swine flu'?
CDC continue to say that, '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 (swine) 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 bird (avian) genes and human genes. Scientists call this a "quadruple reassortant" virus'.
