Swine flu

I'm planning a trip to the south west of the U.S.A. this summer. Everything has been prepared. But with the outbreak of the mexican flu, we may have to rethink our route. It's still 2 months before we leave, so maybe the threat will have disapeared by then. I found a very interesting site which contains a map of all lethal diseases in the entire world. It's combined with google maps so one has a nice overview:
