90% Change Rate on Unstable HA Antigen Range with H9N2 and H5N1 Bird Flu Matches

A recent slight increase in data transparency has allowed a higher quality documentation of the actual change rate for the HA within the ΣPF11 reservoir.  Though hundreds of sequences are being deposited with substantial truncations in important areas, we work with the data that is surfaced and ask for the portions that have been withheld.  Considering the limited availability of raw data, the analyses continue to yield patterns and ratios worthy of report.

More than 90% of the Hemagglutinin positions between 186 and 246, including antigenic areas of the Receptor Binding Domain (RBD/RBS), are on record as polymorphic. Only 6 positions in that range are stable.  Many positions rate multiple changes. The list presented today is certainly not comprehensive. For the sake of brevity, only one section is discussed from one gene segment (HA) covering 61 contiguous amino acid positions. The extensive variation in that short range is documented in the trailing data.

Of course, viral revision is also rapidly occurring in additional HA antigenic areas outside the range of positions documented in this analysis.  The Neuraminidase of the human pandemic H1N1 reservoir is acquiring revisions with homology to Avian and Equine influenza at a ratio even higher than that of the Hemagglutinin being surveyed in this analysis.

The viral reservoir backing this present H1N1 pandemic is far from stable and is actively acquiring new genetics. Current data does not indicate an immediate direction toward stability.

A previous version of this listing may be referenced for tracking.  There you will find details on the causality behind this particular study.
