Hepatitis delta (D) virus is a defective virus that cannot replicate without the aid of another virus, the hepatitis B virus. Rates of hepatitis D and B virus coinfection vary widely throughout the world. Hepatitis D and B virus coinfection in the same individual, however, leads to a higher incidence of chronic liver disease than does infection with hepatitis B virus alone. Hepatitis D virus infection can be prevented by use of the hepatitis B vaccine, since hepatitis D virus replication is dependent on the presence of hepatitis B virus.
