[HIV, HCV, HBV and syphilis surveillance among blood donors in Germany 2008-2010].

The Robert Koch Institute collects and evaluates data on the prevalence and incidence of HIV, hepatitis C (HCV), hepatitis B (HBV) and syphilis infections among blood and plasma donors in Germany according to article 22 of the Transfusion Act. This report includes data from all blood donation services in Germany for 2008-2010. The prevalence for HIV ranged from 6.6-7.0/100,000, for HCV from 68.9-81.6/100,000, for HBV from 116.2-136.6/100,000 and for syphilis from 31.0-42.1/100,000 donations. The proportion of incident infections per 100,000 donations ranged from 0.8-0.9 for HIV, 0.8-1.0 for HCV, 0.3-0.5 for HBV and 1.4-1.6 for syphilis. Since 2001 the prevalence and incidence of HBV and HCV among blood has declined whereas incident HIV infections reached a peak in 2008 and 2010 and show an increasing trend. Also, the proportion of syphilis infections among first time donors was highest in 2010. Significant differences in infection prevalence and incidence were found between the sexes, different age groups and different donation types. In order to optimise donor selection a validated donor questionnaire should be used and confidentiality in all steps of donation should be assured. The possibility of a confidential self-exclusion should be explicitly pointed out to donors.
