  • HDV is transmitted by the parenteral route[Bonino 1985] but has some potential for sexual transmission[Wu 1995; Rosenblum 1992] and is less likely to be transmitted perinatally
  • The major risk factor is cohabitation with an HDV-infected HBV carrier in the setting of an overcrowded family household[Sagnelli 1992; Niro 1999]
