i hate it when people simply call the SWINE FLU just 'H1N1 flu', cause it is not (did the swine flu name aggravate the pig farmers?). swine flu is a particular strain of the the influenza A subtype H1N1 flu. simply saying H1N1 does not differentiate it between past flu viruses, current seasonal flu virus, and the 'swine flu'/'novel H1N1'.
