Hepatitis Information for the Public

What is Viral Hepatitis?

The word "hepatitis" means inflammation of the liver. Hepatitis is most often caused by a virus. In the US, the most common types are Hepatitis A, Hepatitis B, and Hepatitis C. Heavy alcohol use, toxins, some medications and certain medical conditions can also cause hepatitis.


Hepatitis D

Hepatitis D is a serious liver disease caused by the Hepatitis D virus (HDV) and relies on HBV to replicate. It is uncommon in the United States.

Transmission: Contact with infectious blood, similar to how HBV is spread.

Vaccination: There is no vaccine for Hepatitis D.


Hepatitis E

Hepatitis E is a serious liver disease caused by the Hepatitis E virus (HEV) that usually results in an acute infection. It does not lead to a chronic infection. While rare in the United States, Hepatitis E is common in many parts of the world.

Transmission: Ingestion of fecal matter, even in microscopic amounts; outbreaks are usually associated with contaminated water supply in countries with poor sanitation.

Vaccination: There is currently no FDA-approved vaccine for Hepatitis E.
