biggirl, of course we should still be concerned. Even the "regular" flu kills tens of thousands of Americans every year. This will likely add to the total over the next several flu seasons.

Yes, the concern is that it might mutate. (Actually, flu viruses are mutating all the time.) This variety has already grabbed genetic material from human, porcine, and avian strains of influenza. It could very easily combine both virulence and mortality in the same package if it encounters the right conditions or host.

No, infecting yourself is not recommended. The winter (northern hemisphere) flu vaccine will include an H1N1 signature, per WHO agreement within the last week. The vaccine will generate antibodies without infecting most recipients.

I don't expect you to know the answer to this since the national and international media don't, but should we still be concerned with swine flu. As I understood it, it has turned out to be fairly benign, with no greater mortality rate than the garden-variety flu. Is the concern that it might mutate? If so, should we infect ourself now in the hopes that we will be resistant to the more virulent strain? (I know most would say no -- that there's no guarantee it will work later and that there's risk now, but it's a question I wondered. My friend years ago infected herself with chicken pox so that she'd be over it before she was pregnant. Seemed like a wise idea in that case.)

hey, the school board can build a germ free school now. the perfect opening.
