It has none of the typical Russian mutations from last season.
It seems to be the same strain that is in England now, but while England
published >30 HAs at GISAID, Russia published the full genome at genbank !
Now, where did this substrain come from, where was it seen first,
where did it emerge, why is it so successful ?
earliest with that "UK"-strain that I found at genbank is
A/Thailand/34-9912/2010/07/14
also A/Karaj_Iran/5327/2010/12/06 , HA and NA available
amazingly this new strain (the "UK"-strain) which dominates Britain and maybe Europe,Russia,West Asia,...
has nothing to do with all the thousands of published viruses from last season !
It probably emerged from a Cancun-virus, which early in April,May 2009
went to Asia (?) and silently replicated since then in a niche undetectedly.
Its time came when the other strains died in the Northern summer 2010.
Find the country,region,city where it stayed in 2009 and early 2010 !
However, even if it was only in one small village and we had known it
and we had eradicated it - just another strain would probably have taken the place,
now that the competing UK-strain did not increase the human population's immunity.
But when we find and understand these flu-bottlenecks, we may be able to
_choose_ the strain which will be dominant next season and plant it.
So to slowly reduce the virulence of influenza ...
I was curious about A/Ulaanbaatar/190/2011(H1N1),2011/01/11 so I Blasted it at GISAID. Here are the top 20 matches; first the nucleotides and then amino acids.
I find it interesting to see the differences in the 2 Blasts, even though it's the same sequence.

COMMENT This influenza isolate was sequenced as part of the NIAID Genome
Sequencing Center Influenza Project at the J. Craig Venter
Institute. This sample is being submitted as a draft sequence
because after two rounds of targeted finishing some or all segments
do not meet either NCBI or J. Craig Venter Institute standards of
completeness due to low coverage, low quality, ambiguities,
frameshifts, gaps, or other problems.
This work was supported by the National Institute of Allergy and
Infectious Diseases (NIAID), Genome Sequencing Centers for
Infectious Diseases (GSCID) program.

when was it sequenced ? presumably contaminated with ******
182 is out now
download finished , took ~1hour
3.87GB uncompressed , 1:45h
958086 virus records
154773/154788 of them influenza , 3:15h
768MB of flu-records, 134MB compressed
the first group , #1-#35 is the new PA/02 strain
the 2nd group, #37-#136 is the Egypt/Kenya/Iowa strain
#140-#158 is a new Asian strain
all 3 are descendents of Perth/2009 or a similar virus, which may go back to
2009 or 2008. So we do see 3 different strains of H3N2 in humans
all going back to one ancestor from ~2008.
A 2-3 years variation. While ******, ph1n1, has ~1-2 years.
Flu may die each year in all but a few places (India ?) where it stays
yearround and from where it always starts with new strains.
And it doesn't seem to get feedback in those place -viruswise- from what
happens elsewhere.
Find those central flu-base-places and track the evolution there !
Rather than tracking it in the peripheral USA,Europe.
Thanks for further explanation of your pic; I'd like to pass it on to those who are still not quite sure
what they're seeing. Please feel free to ask questions.
First of all, his pics need to be viewed in full size. I use Opera and always "fit to width", which shrinks
the pic to the point that I can't see it properly.
In his green pic, the red lines to the right mark the substrains and the red line at the bottom middle
indicates HA (segment 4). When the pic is fully enlarged, you can better see the pale blue lines that
divide the segments. He has added color in the linked pic to differentiate the 8 segments.
I knew the pixels were mutations but I could never quite put it together until he showed me his table
of the same sequences.
Here's a portion of his table shrunk 50%. You can still see the atcg mutations but look how the pixel
columns begin to form.
And here, you can see even better how the mutation table transforms into a picture with pixel columns.
