Epidemiological data are essential for monitoring trends and outbreaks of infectious diseases in the general population. The reporting system pursuant to the Infection Protection Act in Germany results in a very good quality of timely nationwide data on all reportable diseases including those relevant for the blood supply: HIV, hepatitis C, hepatitis B and syphilis. Notifications of acute hepatitis B and first-time diagnosed hepatitis C infections in the general population showed a declining trend in the past years, but the number of reports of HIV and syphilis infections increased until 2007 especially among men who have sex with men. New preventive strategies should also address changes in sexual behavior. The specific surveillance of blood donors is an important part of the hemovigilance system. The highly effective donor selection process results in a small number of confirmed infections among donors in Germany. The surveillance data enable us to identify specific trends that might challenge blood safety like the increase in HIV infections among repeat donors. Specific evaluations are performed when needed. These additional studies can be used to modify guidelines or recommendations and to (re)evaluate the need for or the effect of further testing.
