    Influenza activity in Europe at out-of-season levels

    Until week 40/2012, the EuroFlu bulletin will be published fortnightly.
    • This issue is based on data reported in week 28/2012 by 29 Member States in the WHO European Region.
    • Consultation rates for influenza-like illness (ILI) and acute respiratory infection (ARI) are now at low levels in all countries in the Region.
    • None of the 32 specimens collected from sentinel sources tested positive for influenza virus.


    Outpatient surveillance for ILI and ARI

    All 23 countries reporting data on intensity reported low intensity, with decreasing or stable trends in clinical activity overall. All 23 countries reporting on the geographical spread of influenza reported no activity.

    During week 28/2012, sentinel outpatient clinics collected 32 respiratory specimens, none of which tested positive for influenza virus.



    Hospital surveillance for severe acute respiratory infection (SARI)

    2 countries reported data for hospital-based sentinel surveillance of SARI in week 28/2012: Georgia and Kazakhstan. 7 respiratory specimens were collected from SARI patients, all of which tested negative for influenza.



    Virological overview

    Specimens from non-sentinel sources yielded 7 influenza detections in week 28/2012: 3 type A unsubtyped and 4 influenza B.

    Since week 21/2012, a total of 405 influenza virus detections was reported: 191 influenza A (47%) and 214 (53%) influenza B. Of the influenza A viruses, 106 (55%) were subtyped: 5 were A(H1N1)pdm09 and 101 A(H3N2).
