Delta agent is a type of virus called hepatitis D that causes symptoms only in people who have a hepatitis B infection.
Alternative NamesHepatitis D virus
Causes, incidence, and risk factorsHepatitis D virus (HDV) is only found in people who carry the hepatitis B virus. HDV may make a hepatitis B infection or existing hepatitis B liver disease worse. It can cause symptoms in people with hepatitis B virus who never had symptoms.
Hepatitis D infects about 15 million people worldwide. It occurs in 5% of people with hepatitis B.
Risk factors include:
- Abusing intravenous (IV) drugs
- Being infected while pregnant (the mother can pass the virus to the baby)
- Carrying the hepatitis B virus
- Having had a hepatitis B infection in the past
- Men having intercourse with other men
- Receiving many blood transfusions
Hepatitis D may make the symptoms of hepatitis B more severe.
Symptoms may include:
- Abdominal pain
- Dark-colored urine
- Fatigue
- Jaundice
- Joint pain
- Loss of appetite
- Nausea
- Vomiting
- Anti-delta agent antibody
- Liver biopsy
- Liver enzymes
Many of the medicines used to treat hepatitis B are not helpful for treating hepatitis D. See hepatitis B.
Persons with long-term HDV infection may receive a medicine called alpha interferon for up to 12 months. A liver transplant for end-stage chronic hepatitis B may be effective.
Expectations (prognosis)Persons with an acute HDV infection usually get better over 2 to 3 weeks. Liver enzyme levels return to normal within 16 weeks.
About 10% of those who are infected may develop long-term (chronic) liver inflammation (hepatitis).
Complications- Chronic active hepatitis
- Fulminant hepatitis
Call for an appointment with your health care provider if you have symptoms of hepatitis B.
PreventionPrompt recognition and treatment of hepatitis B infection can help prevent hepatitis D.
Avoid intravenous drug abuse. If you use IV drugs, avoid sharing needles.
A vaccine is available to prevent hepatitis B. It should be considered by people who are at high risk for hepatitis B infection.

Hepatitis virus comes under which type of virus?
Several diseases of the liver, collectively known as hepatitis, are caused by viruses. The viruses involved, five of which have been reasonably well characterized, come from a wide range of virus families. Hepatitis A virus is a picornavirus, a small single strand RNA virus; hepatitis B virus belongs to the hepadnavirus family of double stranded DNA viruses; hepatitis C virus is a flavivirus, a single stand RNA virus; hepatitis E, also an RNA virus, is similar to a calicivirus. Hepatitis D which is also known as Delta agent is a circular RNA that is more similar to a plant a viroid than a complete virus.
When hepatitis virus has no vaccine to prevent the disease?
Hepatitis C and hepatitis E have no vaccine to prevent the disease. Although there is no vaccine to prevent hepatitis D, you can only get this type if you're also infected with type B. Therefore, hepatitis B vaccine indirectly prevents hepatitis D.
