Abstract
Influenza virus type B strains were unexpectedly detected and isolated in Italy during summer-fall 2008 from three patients travelling to Italy from Lebanon, Senegal and Uzbekistan. The three summer-fall strains matched to a high degree the hemagglutinin (HAl) of influenza virus type B strains circulating in Italy in the second part (January through April) of the 2007/2008 season, and HAl of the type B strains included in the 2008/2009 vaccine (B/Yamagata/16/88 lineage). Surveillance of influenza virus circulation in Western countries also during the summerfall season may help to trace and anticipate the appearance of new influenza virus variants.
