The other thing with the 7% is how can they actually know at this point? They are making an educated guess based on insufficient information. They can only estimate how many people have actually had swine flu in Mexico before this weekend. Many people may have have had it & not reported it because "it's just the flu" or it was a mild case. Now they have people thinking back and saying "oh maybe I had it" but it's too late to test, so are those numbers part of the illness to death ratio?
I think "they" are tossing out a lot of information to be seen to be doing something and 'keep people informed' but even 'they' admit the situation is evolving & they don't know the full picture yet. Most of the world is not prepared to deal with a new disease on a large scale. We only have meds that mostly treat it, no cure & no vax & at this point it's already spread to Europe, the Americas and Australia & NZ. They have to tell everyone something so they can keep a populaton, that gets news updates every 5 minutes, calm. I think any long term stats, positive or negative, at this point should be taken with some doubt.
