Well, if this is a virus (as the annual 'flu' is a virus) it ALWAYS mutates. That is how it survives. That is also why they push a flu vaccine every season...because they know there are different strains of flu and that there will be mutations, they just cannot predict which ones when. So they select the most likely ones, combine them and deliver it up to you every year. Shaken, not stirred.
