*Infants born to infected mothers (very rare) [http://www.cdc.gov/ncidod/diseases/hepatitis/d/fact.htm]
* Carrying the [[hepatitis B virus]]
* Men having sexual intercourse with other men
* Sexual intercourse with HDV infected persons
* Receiving many [[blood transfusions]]

* [[Haemophilia|Haemophiliacs]]
* [[Hemodialysis]] patients  
* Health care and public safety workers  
* Individuals who are not infected with [[HBV]], and have not been [[vaccine|immunized]] against [[HBV]], are at risk of [[infection]] with [[HBV]] with simultaneous or subsequent infection with [[HDV]].

Overview

Common risk factors in the development of hepatitis D include intravenous drug use, sexual intercourse with infected individuals, hemodialysis, and occupational exposure to infected individuals and blood products [1][2].

Risk Factors

Since HDV requires the support of hepatitis B virus for its own replication, inoculation with HDV in the absence of HBV will not cause hepatitis D. Alone, the viral genome replicates in a helper-independent manner, but the viral particles do not exit the cell.[1][2]

When in the presence of hepatitis B virus, risk factors for hepatitis D include:

  • Using intravenous (IV) or injection drugs
  • Being infected while pregnant (the mother can pass the virus to the baby)
  • Carrying the hepatitis B virus
  • Men having sexual intercourse with other men
  • Sexual intercourse with HDV infected persons
  • Receiving many blood transfusions
  • People exposed to unscreened blood or blood products
  • Haemophiliacs
  • Hemodialysis patients
  • Health care and public safety workers
  • Individuals who are not infected with HBV, and have not been immunized against HBV, are at risk of infection with HBV with simultaneous or subsequent infection with HDV.
