Delta Hepatitis (hepatitis D) 2004

Delta hepatitis is a liver disease caused by the hepatitis D virus (HDV). HDV is a defective virus that requires the helper function of the hepatitis B virus (HBV) to replicate. People may become infected with HDV at the same time they acquire HBV (co-infection), or people may acquire the virus after infection with HBV (superinfection). The modes of transmission are similar to those for HBV. HDV is transmitted by percutaneous exposure or sexually through contact with infected blood. Most cases are acquired by exposure to contaminated needles.

There were no reported cases of delta hepatitis in Indiana in 2004; and only one reported case* during the five-year reporting period 2000-2004.

*One case of delta hepatitis occurred in Indiana in 2002. However, due to delayed reporting, this case was not included in the 2002 or 2003 Infectious Disease report.
