In stark contrast to this time last year - when much of Europe was seeing significant H1N1 influenza activity - reports of flu for week 3 of 2012 (while rising slowly) - remain low across Europe - and predominantly H3N2 related.

 

 

Influenza activity continues to rise slowly in the WHO European Region due to A(H3N2)

  • This issue is based on data for week 3/2012 reported by 46 Member States in the WHO European Region.
  • Consultation rates for influenza-like illness (ILI) and acute respiratory infection (ARI) continue to be relatively low in most countries of the Region, but with many countries reporting increasing activity.
  • 29 % of sentinel specimens tested positive for influenza, which is an increase over last week: 95% of these were influenza A.
  • Of the 352 influenza A viruses from sentinel sources that were subtyped, 99 % were A(H3N2). 

    Comment

    Influenza activity has increased consistently over the past several weeks, but influenza detections remain low compared to the same period of the 2010/2011 season. Influenza A and B viruses are co-circulating in the Region, with the vast majority of detections in both outpatient clinics and hospitals being A(H3N2).

  • We’ll get the latest FluView and FluWatch numbers later today for the United States and Canada.
