Hepatitis D virus was first reported in 1977 as a nuclear antigen in patients infected with ... (HBV family) virus to replicate. These agents have rod-like ...
Hepatitis D is caused by the hepatitis D virus (HDV), or hepatitis delta virus; it belongs to the genus Deltavirus. HDV is similar to a satellite virus as it can only propagate in the presence of the hepatitis B virus, depending on the helper function of HBV for its replication and expression. It has no independent life cycle, but can survive ...
The epidemiology of hepatitis D occurs worldwide. [1] Although the figures are disputed, a recent systematic review suggests that up to 60 million individuals could be infected. [ 2 ] The major victims are the carriers of the hepatitis B surface antigen ( HBsAg ), who become superinfected by the HDV, and intravenous drug users who are the group ...
Hepatitis D is a defective virus that requires hepatitis B to replicate and is only found with hepatitis B co-infection. [17] In adults, hepatitis B infection is most commonly self-limiting, with less than 5% progressing to chronic state, and 20 to 30% of those chronically infected developing cirrhosis or liver cancer.

Hepatitis D virus (HDV) is an example of a replication defective, helper dependent ssRNA virus because it requires Hepatitis B virus (HBV) to provide HBV surface antigen (HBsAg) for the encapsidation of its genome. The envelope proteins on the outer surface of HDV are entirely provided by HBV.
