For the geographical spread of influenza indicator, 26 countries reported no activity, while 2 countries reported sporadic activity.
During week 34/2012, sentinel outpatient clinics collected 54 respiratory specimens, of which 1 (1.8%) tested positive for influenza A virus (unsubtyped).
Hospital surveillance for severe acute respiratory infection (SARI)

18 respiratory specimens were collected from SARI patients, all of which tested negative for influenza.
Virological overview
Specimens from non-sentinel sources yielded 4 influenza type A detections in week 34/2012: 2 were not subtyped and 2 were A(H3N2).
Since week 21/2012, 498 influenza virus detections have been reported: 233 (46.8%) influenza A and 265 (53.2%) influenza B.
