EuroFlu - Weekly Electronic Bulletin - Week 22 : 28/05/2012-03/06/2012 - 08 June 2012, Issue N? 448
Influenza activity in Europe is at out-of-season levels
Until week 40/2012, the EuroFlu bulletin will be published biweekly.
Outpatient surveillance for ILI and ARI
Among 27 countries reporting data on intensity, all reported low intensity, with decreasing or stable trends in clinical activity overall.
Of the 27 countries reporting on the geographical spread of influenza, 21 reported no activity and 6 reported sporadic activity.
During week 22/2012, sentinel outpatient clinics collected 108 respiratory specimens, of which 2 (1.9%) tested positive for influenza viruses.
Of the positive specimens, 1 was influenza type A(H3N2) and 1 was influenza B.
Hospital surveillance for SARI
8 countries reported data for hospital-based sentinel surveillance of SARI in weeks 21?22/2012: Armenia, Belarus, Georgia, Kazakhstan, Kyrgyzstan, the Republic of Moldova, the Russian Federation and Ukraine.
59 respiratory specimens were collected from SARI patients, of which 2 tested positive for influenza: 1 A(H3N2) and 1 B.
Virological overview
Specimens from non-sentinel sources yielded 56 influenza detections in week 22/2012: 31 type A (19 A/H3 and 12 A unsubtyped) and 25 influenza B.
Since week 21/2012, a total of 158 influenza virus detections was reported: 93 were influenza A (59%) and 65 (41%) were influenza B.
Of the influenza A viruses, 61 (65%) were subtyped, with 1 being A(H1N1)pdm09 and 60 A(H3).
Comment
Influenza activity is at out-of-season levels throughout the European Region. 1.9% of the samples collected from sentinel sources was positive for influenza virus. From non-sentinel sources, 56 samples were influenza-positive, indicating low influenza activity in the Region.
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.
Erratum:
For Slovakia, the intensity and geographic spread indicator presented in the table and the map are incorrect. Correct indicators are low intensity and no activity.
