The reported national influenza trends indicate that the influenza season is coming to its end in Europe, highlights the Weekly Influenza Surveillance Overview for Week 19.

The 2011–2012 influenza season started late, has been without any clear geographic progression and has varied considerably in its impact from country to country.

During week 19/2012, almost all countries reported low intensity. Virological surveillance for week 19/2012 shows that of 64 sentinel specimens tested by 14 countries, 14.1% were positive for influenza virus.

As the 2011–2012 influenza season is coming to its end, the weekly report will be replaced by a fortnightly report during the off-season period (weeks 21–39/2012).
