37 respiratory specimens were collected from SARI patients, all of which tested negative for influenza.
Virological overview
Specimens from non-sentinel sources yielded 17 influenza detections in week 26/2012: 1 type A unsubtyped, 1 A(H1N1)pdm09 and 15 influenza B.
Since week 21/2012, a total of 360 influenza virus detections was reported: 166 were influenza A (46%) and 194 (54%) were influenza B.
