Evolution of the hemagglutinin segment of H1N1 Influenza Virus.
Cluster 30 (ex 28) is still the most populated. Clusters 33, 34, 35 and 36 could be new emerging strains.
Investigate Influenza virus with entropic metric measures
Cluster 30 (ex 28) is still the most populated. Clusters 33, 34, 35 and 36 could be new emerging strains.
Clusters 33, 34 and 40 are the main circulating strains. Clusters 42 and 43 could be new emerging strains.
Cluster 28 is the most populated, there are no statistically relevant signals of new emerging strains.
The new strains emerged on the winter season 2012/13 are present also at the beginning of winter season 2013/14. Clusters 34 and 43 could be new emerging strains.
The three new strains emerged on the winter season 2012/13, noticed on the last H3N2 analysis, are well populated. No new strain is emerging.
Among the emerging strains, two of them are the most populated, clusters 30 and 31 (23 and 24 in the previous analysis).
According to the analysis, new strains emerged on the winter season 2012/13.
According to the analysis, new strains emerged on the winter season 2012/13 the precursors of which go back to January 2012.
