Hepatitis D

Hepatitis D, which is caused by the hepatitis D virus (HDV), is a disease that infects the liver. It's similar to the other hepatotropic viruses because it causes liver inflammation and produces similar symptoms, but HDV is unusual. It can only infect someone who has hepatitis B because it's a defective virus.
