....I just got back from a seminar on the swine flu and was told that although it's no more lethal than the seasonal flu, because it's a new kind of flu no one has any natural immunity built up for it. As a result, it's more transmissible by about 2.5 times or so. If the mortality rate for swine flu is about the same as seasonal flu but is 2.5 times more transmissible then 2.5 times more folks will die from it. Although the swine flu has been shown to be remarkably similar genetically and thus is more easily treated, the fear is that the disease might mutate when it comes into contact with someone already having the seasonal flu or, worse, avian flu. I got my seasonal flu shot a couple days ago and will the the swine flu shot when it becomes available.
