we have been talking for months about influenza A(H1N1). we have seen the death toll, we have heard of the precautionary measures taken, we have had enough of the rising statistics of casualties. quarantine procedures, suspension of classes, absence with leave and more. have you ever wonder why influenza A is called/labeled H1N1? could it have been H2N2 or H3N1 or any number combination? why H1N1? i found out that this label refers to the two proteins found in the surface of the virus. there are 16 subtypes/strains of H virus and 9 subtypes/strains of N virus found in birds. there are only H1,2 and 3 and N1 and 2 commonly found in humans. the first strain of virus is found in human. so what's in a name? H refers to the hemagglutinin and N refers to the neuraminidase. (could it have been the blood and the nerves?) you follow this up...
