Abstract
The hepatitis B virus (HBV), the agent(s) of hepatitis non-A, non-B (HNANB) and the hepatitis delta virus (HDV) are transmitted by blood, blood products or close contact. The hepatitis A virus (HAV) is transmitted in the first instance by the fecal-oral route. Chronic carriers of HAV are unknown, i.e. HAV can be transmitted by blood only in the relative short phase of viremia. For both HBV and HDV serological tests are available to determine carriers of the virus and to prevent them from donating blood or plasma. In addition, infection with HBV can be prevented by active vaccination. This vaccination also provides protection against HDV infection. Agents of the parenterally transmitted HNANB have not yet been identified and thus no serological tests for viral antigenes or antibodies are available. HNANB is a major problem in transfusion medicine. Today about 90% of posttransfusion hepatitis is caused by the agent(s) of HNANB.
