And finally, the NYT reports from state fairs across the country, where officials are grappling with a new health threat: bug-ridden sightseers are infecting pigs with swine flu. "The whole idea of the animals getting sick from people is a foreign concept," says one state veterinarian. "But that's what we're looking at here." It's no laughing matter: Officials say that if the H1N1 flu strain is allowed to recirculate in pig populations, it could mutate into more virulent and deadly forms. In an attempt to insulate the prize porkers, officials at many fairs now bar visitors from petting the animals and are asking people to wash their hands before approaching the pig pens.
