Actually, this particular subtype of the swine flu identified in the US cases is reportedly completely new and has never been found in pigs or people before. So no one really knows what to expect with it.

There was an interesting little factoid I read this morning that I didn't know. There were "only" eight cases identified in New York, but that's only because the Health Department team sent to take swabs at that high school got stuck in traffic, and by the time they arrived, school had already let out for the day so most students were already gone. So far, I don't think we really know the health status of the rest of the students who went on that trip to Mexico. Anyway, little bits of information like this are just another reminder to me that what we read in the news is often--actually, usually--not the whole story, even if the facts within the story itself are accurate.
