The number of confirmed cases continues to rise in the U.S. South Carolina has held steady at 36 cases for some time, knock on wood (my head, my wife says). 9 deaths from 6,552 cases as of 5/23/09. Go to post Update 11 to see my chart.
I read an interesting theory. They proposed the great pandemic of 1918 was of type H1N1 also. There was a tremendous death toll. In subsequent years, with the same type, the death toll fell. Then another type became predominant. H1N1 may have come back about 30-40 years ago. So older adults were exposed to the H1N1, which may explain why they seem to be more resistant. The deaths are in younger adults and children. We'll see.
