Hepatitis D virus (HDV)

Microbiology

Notes

Hepatitis D (Hepatitis Delta virus) is a blood borne virus
Hepatitis D virus can propagate only in people already infected with the Hepatitis B virus (HBV).
Super-infection and co-infection with HDV results in more severe complications compared to infection with HBV alone
Serology for Hepatitis D IgG and IgM is the screening test of choice.
Hepatitis D PCR is also available in relevant circumstances
