Pigs are well known as genetic mixing vessels for human and avian influenza viruses (1,2), and swine influenza viruses (SIVs) occasionally infect humans (3-5).

While workers reportedly spent only a limited amount of time in the affected swine barns each day, and the number of workers entering each barn daily was small, the fact that half of the farms tested positive for influenza virus in aerosols, surfaces, and/or swine oral fluids suggests that exposure to swine influenza viruses was taking place and may be significant enough to result in infection.

The current H1N1 influenza virus represents a quadruple re-assortment of two swine flu strains, one human and one avian strain of influenza viruses, the largest proportion of genes coming from swine influenza viruses [5].

Secondary infections in swine flu

Contemporary vaccines against Porcine Reproductive and Respiratory Disease Syndrome viruses (PRRSV) and Swine Influenza viruses (SIV) are composed of either live attenuated viruses that risk frequent recombination between viral and vaccine strains and reversion to virulence or inactivated viruses that confer short term immunity.

However, due to insufficient surveillance of swine influenza viruses, exact reassortment events are yet to be investigated (11).

Different influenza virus strains display clearly different preference for sialyl linkages at the C-2 position catalyzed by specific sialyltransferases: human and classical swine influenza viruses prefer to bind sialic acids attached to galactose by [alpha]2-6 linkage, 55),56) whereas avian and equine viruses prefer sialic acids with [alpha]2-3 linkage instead; Fig.

Andrew McCammon made a computer movie of slight structural shifts that can occur in the neuraminidase 1 enzyme (the N1 in H1N1), a protein found in avian and swine influenza viruses.
