Dear Aiesha...
it's been a long time since my last post...dont have any idea to write on this virtual message in a blog..
but..there's so much things happen around me...around u...

H1N1 is getting worst...there's a positive case in the camp...but thank God it is not a pandemic yet..
How do they get the H1N1 name..?

Influenza A virus strains are categorized according to two proteins found on the surface of the virus: hemagglutinin (H) and neuraminidase (N). All influenza A viruses contain hemagglutinin and neuraminidase, but the structures of these proteins differ from strain to strain, due to rapid genetic mutation in the viral genome.
Influenza A virus strains are assigned an H number and an N number based on which forms of these two proteins the strain contains. There are 16 H and 9 N subtypes known in birds, but only H 1, 2 and 3, and N 1 and 2 are commonly found in humans

-quoted from wikipedia-

hope we'll can get through all this...




The N in H5N1 stands for "Neuraminidase", as depicted in this ribbon diagram.

The H in H5N1 stands for "Hemagglutinin", as depicted in this molecular model.
