I’ve heard it said that older Americans probably have some resistance to H1N1 because it is simply an adaptation from previous strains. Maybe that’s correct, maybe it’s not. But it would make sense, as this strain seems to hit younger Americans more.
I wonder what they mean by “average victim’s age”...
because if you had 100 2 yr olds, and 20 80 yr olds, the average age would be 15...
but none of the victims would be 15...
