Infektionsepidemiologische Daten von Blutspendern 2006

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. The surveillance data permit an assessment of the occurrence of infections in the blood donor population and consequently the safety of the collected donations. This report includes data from all blood donation services in Germany for 2006. Due to the revision of the Transfusion Act in 2005 not only the number of donations but also the number of donors has become available for analysis. More than 500,000 donations or blood samples from new donors and about 6 million donations collected from ca. 2.3 million repeat donors were screened in 2006. The prevalence for HIV was 6.2/100,000, for HCV 76.2/100,000, for HBV 150.2/100,000 and for syphilis 34.4/100,000 donations. The rate of seroconversions/100,000 donations was 0.8 for HIV, 1.1 for HCV, 0.7 for HBV and 1.6 for syphilis. The analysis showed a very low incidence of HIV, HBV und syphilis with marginal changes compared to previous years. The prevalence and incidence of HCV among blood donors was once again declining.     

Infektionsepidemiologische Daten von Blutspendern in Deutschland 2007

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 §22 of the Transfusion Act ("Transfusiongesetz"). The surveillance data permit an assessment of the occurrence of infections in the blood donor population and consequently the safety of the collected donations. This report includes data from all blood donation services in Germany for 2007. Due to the revision of the Transfusion Act in 2005, not only the number of donations but also the number of donors is now available for analysis. Nearly 550,000 donations or blood samples from new donors and more than 6.24 million donations collected from approximately 2.43 million repeat donors were tested for transfusion-relevant infections in 2007. The prevalence for HIV was 8.0/100,000, for HCV 70.0/100,000, for HBV 132.5/100,000, and for syphilis 36.8/100,000 donations. The proportion of seroconversions/100,000 donations was 0.6 for HIV, 1.1 for HCV, 0.6 for HBV, and 1.7 for syphilis. The analysis showed a very low incidence of HIV, HBV, and syphilis with marginal changes compared to previous years. The prevalence and incidence of HCV among blood donors was once again declining.     

Infektionsepidemiologische Daten von Blutspendern 2005

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. The surveillance data permit an assessment of the occurrence of infections in the blood donor population and consequently the safety of the collected donations. This report includes data from all blood donation services in Germany for 2005. In total, 6.26 million donations or blood samples from prospective donors were screened. The prevalence of the relevant infections was 6.1/100,000 for HIV, 81.2/100,000 for HCV, 143.9/100,000 for HBV and 35.6/100,000 donations for syphilis. The rate of seroconversions/100,000 donations was 0.9 for HIV, 1.4 for HCV, 0.9 for HBV and 2.3 for syphilis. The analysis showed a very low incidence of infections with a decreasing trend for HCV infections among first time donors and an increase in incident HIV and syphilis infections since 1999. The latter has to be monitored carefully and possible causes need to be evaluated.     

Prevalence of HIV,syphilis, hepatitis B,and hepatitis C among entrants to Maryland correctional facilities

Although high prevalence of hepatitis C virus (HCV) in correctional institutions has been established, data are sparse regarding the comorbidities of hepatitis B virus (HBV), HCV, and human immunodeficiency virus (HIV), all of which may complicate the management of HCV. This study sought to estimate the prevalence and correlates associated with HCV prevalence among entrants into the Maryland Division of Correction and the Baltimore City Detention Center. Participants included all newly incarcerated entrants between January 28 and March 28, 2002. Excess sera with identifiers removed from samples drawn for routine syphilis testing were assayed for antibodies to HIV and HCV and for HBV surface antigen and surface and total core antibodies. Separately, all HIV-positive specimens were tested using the serological testing algorithm for recent HIV seroconversion. Of the 1,081 immates and 2,833 detainees, reactive syphilis serology was noted in 0.6% of the combined population; HIV seroprevalence was 6.6%; HCV prevalence was 29.7%; and 25.2% of detainees and prisoners had antigen or core or surface antibodies to HBV. A multivariate analysis of predictors of HCV positivity indicated that detainees, women, whites, older age groups, those who were HIV seropositive, and individuals with past or present infection with HBV were significantly more likely to be positive for HCV. These data indicate that hepatitis C remains an important public health concern among entrants to jail and prison and is complicated with coinfections that need to be addressed for effective treatment.     

HIV-, HCV-, HBV- und Syphilissurveillance unter Blutspendern in Deutschland 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.     

Bericht des Robert Koch-Instituts zu den Meldungen nach § 22 Transfusionsgesetz für die Jahre 2001 und 2002

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. The surveillance permits an assessment of the occurrence of infections in the blood donor population and consequently the safety of the collected donations. This report includes data from all blood donation services in Germany for 2001 and 2002. Altogether 5.71 million and 6.63 million donations or blood samples from prospective donors were screened in 2001 and 2002, respectively. The analysis showed a very low incidence of infections with a decreasing trend for HCV infections since 1997 but a slight increase in HIV infections in 2001-2002 compared to 1999-2000. The prevalence of the relevant infections/100,000 donations was 4.7 for HIV, 94.7 for HCV, 159.0 for HBV and 33.4 for syphilis in 2001. The rate of seroconversions/100,000 donations was 0.5 for HIV, 1.6 for HCV, 1.4 for HBV and 1.6 for syphilis in 2001. In 2002 the prevalence/100,000 donations was 7.5 for HIV, 97.4 for HCV, 164.1 for HBV and 31.9 for syphilis. The rate of sero-conversions/100,000 donations in that year was 0.7 for HIV, 1.5 for HCV, 1.2 for HBV and 1.9 for syphilis. The quality of the reported data has improved significantly compared to previous years. Still, some problems remained with the differentiation of the data according to sex, age and interval between donations and the reporting by individual blood donation centres as required by the Transfusion Act.     

Infektionsepidemiologische Daten von Blutspendern 2003–2004

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 in accordance with Article 22 of the Transfusion Act. This surveillance permits an assessment of the occurrence of infections in the blood donor population and consequently the safety of the collected donations. This report includes data from all blood donation services in Germany for 2003 and 2004. Altogether 7.09 million and 6.37 million donations or blood samples from prospective donors were screened in 2003 and 2004, respectively. In 2003 the prevalence rates of the relevant infections (per 100,000 donations) were 8.2 for HIV, 99.3 for HCV, 158.9 for HBV and 34.4 for syphilis. In 2003 the rates of seroconversion (per 100,000 donations) were 0.8 for HIV, 1.2 for HCV, 1.0 for HBV and 1.5 for syphilis in 2003. In 2004 the prevalence rates (per 100,000 donations) were 4.8 for HIV, 85.3 for HCV, 156.3 for HBV and 36.8 for syphilis. In 2004 the rates of seroconversion (per 100,000 donations) were 0.9 for HIV, 1.3 for HCV, 0.6 for HBV and 2.0 for syphilis. The analysis showed a very low incidence of infections with a decreasing trend for HCV infections and an increase in HIV and syphilis infections. The latter needs to be monitored carefully and possible causes evaluated. The quality of the reported data has improved compared to previous years. Still, some problems remain with the differentiation of the data according to sex, age and interdonation interval as well as reporting by individual blood donation centres as required by the Transfusion Act
