On account of the high infection rate but low mortality rate in pigs, the OIE (World Organisation for Animal Health) does not classify swine influenza as a reportable or notifiable animal disease (OIE, 2009). Surveillance is conducted by scientific networks.
OFFLU, a network of expertise on animal influenza, has existed since 2005 when it was created jointly by the OIE and the FAO (Food and Agriculture Organization of the United Nations). Its objectives are:
In Europe, the European Commission's research program funded the coordination of the European Surveillance Network for Influenza in Pigs (ESNIP). ESNIP is a union of various laboratories working with swine influenza viruses. The primary aim of ESNIP was to standardise the methods used for influenza detection and surveillance.
In Germany, the Federal Ministry of Education and Research funded the FluResearchNet consortium between 2007 and 2013. Its activities are focused on controlling the effects of influenza epidemics in humans and animals in order to reduce the risk of future pandemics. Today, FluResearchNet is an open network for all scientists working with influenza viruses in Germany.
In September 2011, the Friedrich Loeffler Institute (FLI) assumed the role of Reference Centre for Swine Influenza designated by the Food and Agriculture Organization of the United Nations (FAO).
In the event of an actual or suspected outbreak of swine influenza, the FLI carries out the initial pathogen diagnosis and typing at the request of the countries concerned. In addition, it provides the FAO with assistance in the surveillance and control of these infections, as well as in the quality assurance of diagnostic methods and harmonization with other reference laboratories.
