Mexican swine flu has a complex ancestry containing parts from two previous swine flu viruses and gene segments that originated in birds or humans. The strain of the virus derives its name from the proteins found on the surface of the envelope in this case haemagglutinin (H) and neuraminidase (N. These proteins determine the type of host cell the virus will latch on to.
