BOSTON, Dec. 28 /PRNewswire/ -- A common question asked at current scientific conferences is: "Where did bird flu go?" The recent decrease in reported H5N1 human cases and bird outbreaks might indicate that the virus has become dormant. However, quantitative analysis by Replikins, Ltd. released yesterday of human H5N1 virus sequences in 2006 has found that the Replikin Count(TM) has significantly increased beyond all annual previous levels reported in chickens and humans. The Replikin Count(TM) determined by virus protein software analysis, provides an index of the capacity for virus rapid replication. The Replikin Count(TM) is defined as the number of replikin peptide sequences per 100 amino acids of virus protein, that is concentration, and is independent of the number of specimens examined. Rather than declining, the Replikin Count(TM) in humans in 2006 has risen 35% over that in 2005, and outstripped the Count in all reported chicken H5N1 virus specimens, both with reference to the mean and the range, of the peptides in all human H5N1 virus specimens reported by the National Library of Medicine. With the rise in Replikin Count(TM) in human H5N1, (3.7(+/-4.1) in 2005 to 5.0(+/-5.9) in 2006, p
