tracking the H1N1 swine flu

Henry Niman has created a helpful google map to track the incidence of the H1N1 swine flu.  Undoubtedly those who are studying the origins and diffusion of the swine flu will be working with a much more fine-grained map of individual networks and social interaction.  The H1N1 swine flu outbreak entry on wikipedia is also very informative (though obviously subject to corrections).
