Question: why do a person has to be infected with Hepatitis B to get Hepatitis D? I mean what is the relation between this co-infection, and what is teh mechanism in which this co-infection occurs

Answer: Hepatitis D is a "defective" virus, in that it lacks a particular protein necessary for the virus to successfully replicate and package itself inside host cells. In order for the virus to replicate and grow, it has to "borrow" a protein from the Hepatitis B virus. It is blood borne, like HepB. If a person is immunized against Hepatitis B, then they are automatically protected against the Hep D virus (since they cannot be infected by Hep B, Hep D cannot survive and spread inside the host).
