Based on FluNet reporting (as of 14 November 2014, 13:40 UTC),during weeks 43 to 44 (19 October 2014 to 1 November 2014), National Influenza Centres (NICs) and other national influenza laboratories from 51 countries, areas or territories reported data. The WHO GISRS laboratories tested more than 44 937 specimens. 1978 were positive for influenza viruses, of which 1434 (72.5%) were typed as influenza A and 544 (27.5%) as influenza B. Of the sub-typed influenza A viruses, 60 (6.9%) were influenza A(H1N1)pdm09 and 813 (93.1%) were influenza A(H3N2). Of the characterized B viruses, 87 (96.7%) belonged to the B-Yamagata lineage and 3 (3.3%) to the B-Victoria lineage.
Due to changes in data collection platforms, data from the WHO Regional Office for Europe are temporarily not available at global level. Those data will be uploaded to FluNet and FluID as soon as possible. Information on European influenza activity can be found at http://www.flunewseurope.org/
