| |
| HDV (hepatitis D virus) is a defective single-stranded RNA virus that requires the helper function of HBV to replicate. HDV requires HBV for synthesis of envelope protein composed of HBsAg, which is used to encapsulate the HDV genome.

| == Pathophysiology & Etiology==
| |
| Hepatitis D is a liver disease caused by the hepatitis D virus (HDV), a defective virus that needs the hepatitis B virus to exist. Hepatitis D virus (HDV) is found in the blood of persons infected with the virus.
| |
| | |
| *Occurs when blood from an infected person enters the body of a person who is not immune.
| |
| *HBV is spread through having sex with an infected person without using a condom (the efficacy of latex condoms in preventing infection with HBV is unknown, but their proper use may reduce transmission);
| |
| *By sharing drugs, needles, or "works" when "shooting" drugs;
| |
| *Through needlesticks or sharps exposures on the job; or
| |
| *From an infected mother to her baby during birth.
