    Hi Dr. Racaniello,

    I was listening to TWIV 75 and noted the surprising comment
    that influenza apparently does not evolve rapidly in domestic pigs. First, can
    the domestic pig be an efficient influenza “mixing vessel” if it is
    infrequently infected and produces little reassortment? Second, there is a
    theory that the rapid movement of troops returning from WW1 in 1918 selected
    for increased virulence of the Spanish Flu. (Virulent variants don’t need to
    survive their hosts to propagate.) Wouldn’t the same concept apply to pigs, with
    human handlers, high population densities, and agricultural fairs efficiently
    transporting virus from pig to pig? I would expect selection for variants, or are my assumptions wrong?

    Best,

    Bruce
