The Austrian Reference Centre for Influenza Epidemiology at our Institute of Medical Microbiology and Hygiene Vienna in our Public Health Division is responsible for recording the epidemiological situation of influenza in Austria on the basis of a clinical and a virological sentinel surveillance system as well as laboratory reports of influenza virus detections from a further six virological laboratories.

The estimated value of the weekly incidence of ILI (influenza like illness) is calculated at weekly intervals and has been published on our AGES Influenza homepage since the beginning of the 2009/2010 season. The data comes from the sentinel ILI surveillance system established in 1992/1993, which consists of the influenza information system of the Municipal Department 15 of the City of Vienna, the influenza information system of Department 7 of the City of Graz and the influenza surveillance system for the greater Innsbruck area.

Since the beginning of 2012, the ILI case data from all three flu information systems in Vienna, Graz and Innsbruck have been processed once a week by the Reference Centre for Influenza Epidemiology and sent to the Federal Ministry of Labour, Social Affairs, Health, Care and Consumer Protection (BMASGPK), from where they are sent to TESSy (The European Surveillance System) and from TESSy to the WHO/EuroFlu.
