Influenza increasing in much of Europe: ECDC
Increased influenza activity is being reported in many parts of the European continent, particularly in countries of north-western Europe, according to the European Centre of Disease Prevention and Control’s (ECDC) weekly surveillance report Jan. 11.
Sixteen European countries are reporting increasing trends in influenza activity, up from nine countries in the previous report.
Twelve countries reported medium (11) – or high-intensity transmission (Norway). The geographic pattern of influenza activity was reported as widespread by ten countries. Countries in northern and western Europe were most affected.
Since week 40 of 2012, of all influenza virus detections in sentinel specimens, 44% were type A and 56% were type B viruses. Of influenza A viruses subtyped, 51% were A(H3) and 49% were A(H1). The virological pattern seen in Europe is different from that being reported in North America.
In the United States, influenza A predominates with H3N2 being the most common strain.
167 patients with laboratory confirmed cases of influenza required hospitalization in four countries.
Only Romania is seeing decreasing trends in influenza activity on the continent.
The ECDC says it will continue to monitor and report influenza activity in Europe on weekly basis throughout the season.
