Hepatitis D virus (HDV) infections occur only in those who are infected with HBV.
- Hepatitis D virus (HDV) is a ribonucleic acid (RNA) virus that requires hepatitis B virus (HBV) for its replication. HDV infection occurs only simultaneously or as super-infection with HBV.
- The virus is transmitted through contact with the blood or other body fluids of an infected person.
- Vertical transmission from mother to child is rare.
- Approximately 15 million people across the world are chronically coinfected with HDV and HBV1
- Currently there is no effective antiviral treatment for hepatitis D.
- Hepatitis D infection can be prevented by hepatitis B immunization.
* The dual infection of HDV and HBV can result in a more serious disease and worse outcome. Hepatitis B vaccines provide protection from HDV infection.
