2009 influenza A (H1N1) pandemic

The 2009 influenza A(H1N1) pandemic was declared over in August 2010 by the World Health Organization. Europe has now entered a new inter-pandemic phase of seasonal influenza.

Threats and outbreaks reports

  • Daily update on the 2009 pandemic: Daily updates on the spread of the pandemic in Europe and in the rest of the world and on the reported cumulative numbers of deaths due to the pandemic. The last daily update was no longer published as of 20 January 2010.

Surveillance and disease data

 
 
 
 
EU case definitions: At the request of the European Commission, ECDC provided a technical document which served as basis for a European case definition that was adopted on 1 May 2009. This enables an amendment to Decision 2002/253/EC so that it integrates clinical, laboratory and epidemiological criteria for influenza A(H1N1)v virus infection, as well as three case classification definitions to be used in all Member States, covering ‘cases under investigation’, ‘probable cases’ (those showing flu-like symptoms and likely exposure to the disease) and ‘laboratory confirmed cases’.
Having a common case definition means that European countries can collect and report comparable epidemiological data. This gives epidemiologists the information they need to be able to study the pandemic and increase their knowledge about the disease.
