The Austrian Reference Center for Influenza Epidemiology at our Institute of Medical Microbiology and Hygiene Vienna in our PublicHealth Business Unit 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.

At weekly intervals, the estimated weekly incidence of ILI (influenza like illness) is calculated and published on our AGES homepage Influenza since the beginning of the 2009/2010 season. The data originate from the sentinel ILI surveillance system established since 1992/1993, which consists of the influenza information system of Magistrate 15 of the City of Vienna, the influenza information system of Dept. 7 of the City of Graz, and the influenza surveillance system Greater Innsbruck. Since the beginning of 2012, ILI case data from all three influenza information systems Vienna, Graz and Innsbruck have been processed once a week by the Reference Center for Influenza Epidemiology and sent to the Federal Ministry of Social Affairs, Health, Care and Consumer Protection (BMSGPK) for transmission to TESSy (The European Surveillance System) and from TESSy to WHO/EuroFlu.
