Abstract
Influenza A(H3N2) viruses are predominating and causing most outbreaks in North America (Canada and United States) and in some European countries (Finland, Norway, Portugal, Spain and the United Kingdom). A rising trend in influenza A(H3N2) activity has been observed. The only outbreak due to influenza A(H1) virus was reported in Iceland but has declined since week 45.
