This conclusion is a production which I statistcs from 1918 to 2009,

there are so many web or questions which infer that why the American don't worry about the swine flue,

from 1931, there existed the swine flu record in America,

before 1970, after or at an interval of 3 years there would happen the swine flue,

from 1970, especially, from 2000, every year you can find the swine flu in America, and China,

from the time, I guess that the swine flu is normal,

this is a common disease in the world.

when you read this ,you can get the answer,

this is completely analysis by myself

but I am sorry i can not share the data with us.

The infections of swine flu among human beings  have been recorded several times in the history. However, the RNA chains and protein structure of the flu virus are changing dramatically from time to time. That's why we can not control it effectively as the other well known viruses. That's a battle between creatures on earth  rather than a disease we have not figured out a way to deal with .
