Why pigs?

Influenza viruses can exist endemically in pigs as well as birds and other species. The current strain of interest, swine flu, is endemic in pig populations in Mexico but has now spread to people. But, influenza viruses are notoriously promiscuous and can rearrange genetic material to produce hybrid strains. An emerging strain that is both virulent, relatively lethal and can be transmitted between people is the one to worry about.
