Here you find a list of all published ECDC influenza risk assessments on the topics: Seasonal influenza, avian influenza, 2009 influenza A(H1N1) pandemic and swine influenza.
Seasonal influenza risk assessments: There is a logic in considering influenza as a ‘continuous’ disease but with enough annual variation to justify deserving the annual preparation of risk assessments year on year which may be reviewed and updated in season: new influenza viral strains mix with and sometimes replace old influenza viruses; a good example of this is the influenza A(H1N1) pandemic virus which now is the most frequently isolated influenza virus in Europe during the winter influenza season, becoming a ‘seasonal’ virus.
It is for this reason that ECDC will regularly update its ‘seasonal influenza risk assessments’ during the ‘in season’ period drawing on a wide range of experts. This approach was undertaken in 2010/2011 (1), was described by ECDC in the Bulletin of the WHO (2) and recommended by the Independent Fineberg Committee whose recommendations were adopted by the WHA in May 2011.(3)
2009 influenza A(H1N1) pandemic risk assessments: In April 2009, ECDC produced an initial assessment of the public health risk to Europe from the newly emerging strain of influenza. The risk assessments were continually updated as the situation evolved and more evidence became available.
