Abstract

The 2011 influenza season (May to October) in the southern hemisphere was dominated by the A(H1N1) viruses that emerged during the 2009 influenza A(H1N1) pandemic and influenza B viruses, although the proportion of these two varied between and within countries. Some influenza A(H3N2) viruses were also seen. We discuss here the preliminary implications for Europe of the 2011 influenza season in five temperate southern hemisphere countries.
