Transmission: Hepatitis D is spread through contact with infected blood.
Prevention: Hepatitis D is only found in people who are already infected with the hepatitis B virus. People not already infected with hepatitis B, should get the hepatitis B vaccination. To reduce exposure, avoid sharing needles and other items such as toothbrushes, razors or nail scissors with an infected person. It is also wise to avoid getting tattoos or body piercings from unlicensed facilities.
Treatment: Conditions may improve with administration of a-interferon, however no effective antiviral therapy is currently available for hepatitis D.
