Transmission: hepatitis D is passed on through contact with infected blood.
Prevention: hepatitis D only occurs in people who are already infected with the hepatitis B virus. People who are not already infected with hepatitis B can therefore prevent hepatitis D infection by getting vaccinated against hepatitis B. Avoid sharing needles and other items such as toothbrushes, razors or nail scissors with an infected person. You should also avoid getting tattoos or body piercings from unlicensed facilities.
Treatment: treatment for hepatitis D consists of interferon but it is not very effective.
