EuroFlu - Weekly Electronic Bulletin Week 39 : 27/09/2010-03/10/2010 - 08 October 2010, Issue N? 370
Low levels of influenza activity in Europe
Current situation: week 39/2010
Clinical consultation rates for influenza-like illness (ILI) and acute respiratory infection (ARI) are at low levels throughout the WHO European Region. Only Switzerland has reported laboratory-confirmed influenza in sentinel practices last two weeks, indicating a low level of influenza activity in the Region.
Virological update: week 39/2010
Sentinel physicians collected 221 respiratory specimens, 1 of which tested positive for pandemic (H1N1) 2009 influenza virus. Out of 1919 specimens collected from non-sentinel sources, 16 tested positive: 11 type A viruses (8 A unsubtyped, 1 pandemic A (H1N1) and 2 seasonal A(H1) viruses) and 5 influenza B viruses.
Cumulative virological data from week 22/2010
From week 22/2010 to week 39/2010, 162 influenza virus detections in sentinel specimens were reported: 33 were influenza A (20.4%) and 129 (79.6%) were influenza B. Of the influenza A viruses, 15 (45.5%) were subtyped, with 7 being pandemic A(H1) and 8 seasonal A(H3N2).
Comment
Influenza activity is at a low level throughout the European Region. The viruses characterized to date are similar to those recommended as components of influenza vaccines for use in the 2010?2011 northern hemisphere influenza season.
Influenza activity in the temperate regions of the southern hemisphere
During the ongoing influenza season in the temperate zones of the southern hemisphere, detections of pandemic (H1N1) 2009 influenza, influenza B and influenza A(H3N2) and are all being reported, amid circulation of other respiratory viruses. Additional information on influenza circulation in the southern hemisphere is available from WHO headquarters.
Further information
The EuroFlu bulletin describes and comments on influenza activity in the 53 countries in the WHO European Region. Further information can be obtained from the WHO/Europe and WHO headquarters web sites.
