Good point. If I knew how to change it I would.


gman55> if H5N1 has aquired E627K, then what else is needed for it to go human to human more rapidly than it is now? The S227N? Basicly, can you please put it into laymans terms please? I am still confused as to what E627K and S227N are.

They are both HUMAN gene sequences, which have never before been seen in avian influenza. H5N1 has already aquired the E624K sequence and if it should recombine with any of the above listed and incorporate S227N, then it would have the means for effiecient human to human transmission.
