Okay, I will try to be the level-headed one

-- can we say "ironic"? Anyway, this is my viewpoint on what I have seen and read so far (which is a LOT).
1. The CDC released information yesterday that this strain of flu is lacking the genes that made the 1918 flu so deadly.
2. Many of the cases we are seeing are in fact, people who went to Mexico and those that came in contact with those people afterwards.
3. Mexico says their cases are leveling out.
4. The number one preventions are washing your hands and sanitizing them.
I really think your trip will be okay -- it better be, because I am leaving two weeks after you!
And I don't think you are being selfish -- my top personal concern (I have global concerns, too) about swine flu is how it will affect my trip.
