Hepatitis C in Austria 1993-2000: reporting bias distort HCV epidemiology in Austria.
From 1993 to 2000 in Austria, the notification system registered 2232 cases of hepatitis C whereas 10 607 hospital cases were reported in the hospital discharge register (HDR). These differences can be explained by under-reporting due to lax reporting behaviour and stigma associated with this disease. The distribution of HCV infection varied geographically. The notification data showed the highest incidence rates in Tyrol, while HDR data showed highest hospitalisation rates in Vienna and Lower Austria. This study highlights the urgent need for a clear case definition at the national level and an electronic reporting system.
