Moldova, a neighbor of the Ukraine, demonstrates extensive NA syn407V, but is missing the HA area for the syn413K on most sequences. 5 of 7 from Moldova with complete HA sequences display the cross segment linkage.
Expect to see many sequences from the Ukraine on this particular background when HA and NA are deposited for review as most of the recent published Hemagglutinins do carry the syn413K and the published Neuraminidase match the syn407V. Chernihiv452 from the Ukraine with a mixture of 225D, 225G, 225N and 225S carries the syn413K, but has no NA published. A more comprehensive deposit of these two antigenic gene segments (HA and NA) from the Ukraine would allow a definitive conclusion.
Areas covered include Texas (3), the Northeastern United States (4), China (2), Singapore, Australia (2), the Ukraine (18), Moldova (5), Russia (11), Iraq (3), Norway (2), Sweden and extensive penetration in Spain (15 sequences). This particular background pattern may precurse 225G and mixtures of 225D / 225G. If LvivN6 is officially confirmed as a vaccine escape event, these cross-segment pairs may be surveilled as potential future effectors of vaccine efficacy failure.
Publication of the remaining Neuraminidase segments for the 33 Norwegian and Japanese specimens bearing HA syn413K would allow a more precise review. Although 9 of the recent sequences from Norway carry syn413K, none of the 225E strains from Norway have the syn413K. The patterns are highly suggestive that all of the Norse 225G strains do. The 2009-12-29 release of the NA for Norway2924 confirmed that previous suggestion.
The Orenburg2974 sequence from Russia also carries 225N on this background. Bryansk2971, also from Russia with presumably fatal 225G from the lung, demonstrates the syn413K but has no entry for the Neuraminidase to confirm this cross segment linkage.
If RBS revisions at amino acid 225 are, in fact, instructive of high pathogenicity, then Russia is in the FlightPath for a more virulent winter and the Ukraine has presently built a fog of miasma that appears to be capable of spreading across the globe.
