Hepatitis D can be found in the blood, semen, vaginal fluids, and other body fluids of people who are infected. Transmission happens when infected body fluid enters another person’s body. The hepatitis D virus will remain in the body only if hepatitis B virus is also present. 

Hepatitis D virus is most commonly transmitted in the same ways as hepatitis B.

  • Sex with an infected partner
  • Contact with the blood of an infected person
  • Sharing of needles, syringes, razors, or toothbrushes with an infected person
  • Mother-to-child transmission during childbirth

There are two types of hepatitis D infection:

  • Co-infection, in which a person is infected with hepatitis D and hepatitis B at the same time
  • Superinfection, in which a person who is already infected with chronic hepatitis B is then infected with hepatitis D

Hepatitis D is not transmitted through shaking hands, coughing, sneezing, breastfeeding, or sharing cups and utensils.
