Swine Flu Tutorial

I did a swine flu interview the other day on Public Radio International’s To the Point. Most valuable moment: Dr. Georges Benjamin of the American Public Health Association does a really nice job of explaining how the flu virus works—and why it can change so dramatically (or, as he puts it, “makes a mistake”) as it reproduces. (He starts talking around minute 24, for those of you in the mood for a short biology lesson.)
