Can someone tell me what does the 'H' and 'N' means on H1N1 virus?

H1N1 is a serologic classification which identifies the exact subtype of the influenza virus... there are two main proteins on the envelope of the influenza virus - hemagglutinin and neuraminidase - that are critical to the mechanism of infection and replication of the influenza virus.

These two proteins are known to exist in a number of different configurations, 16 for hemagglutinin and 9 for neuraminidase and each configuration is numbered. This means that H1N1 is hemagglutinin type 1 and neuraminidase type 1.

H1N1 has the same hemagglutinin protein structure as H1N2 and the same neuraminidase protein structure as H5N1.

"Swine flu" is just a generic term for any influenza virus that is transmitted between pigs. Once the flu crosses over to another species, like us, it's no longer a "swine flu" but a "human/dog/seal/bird flu of swine origin".

So calling the current Influenza A H1N1 virus a swine flu doesn't cirrectly communicate the human-to-human transmissibility aspect of the virus. H1N1 has, just like in 1918, become a "human flu.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
