Home > Health Library > Hepatitis D
Infection with the hepatitis D virus (HDV), or delta agent, occurs only in people who are already infected with the hepatitis B virus (HBV). HDV infection may make HBV infection more severe.
In people who have long-term (chronic) HBV infection, HDV infection can make liver disease worse. Or it can cause a person who did not have symptoms before to develop liver problems more rapidly.
Vaccination against hepatitis B will also prevent hepatitis D virus infection.
Hepatitis D virus infection is rare in the United States.
