What is Hepatitis D?

Hepatitis D is a virus that infects the liver. This virus requires co-infection with the hepatitis B virus (HBV). It may occur as an acute co-infection, or as a super infection in persons with chronic HBV.

How is it spread?

Spread is mainly through exposure to infected blood and body fluids, contaminated needles,syringes, and sexual transmission. People are most infectious just before the onset of acute illness.Blood is potentially infectious during all phases of active infection.

What is the incubation period?

The incubation period is from 2-8 weeks. Preventive measures Hepatitis B vaccine prevents infection with hepatitis D. Avoid exposure to body fluids and wear a condom when having sex.

Due to limited supply, HPEPH will initially be prioritizing available bivalent vaccine for residents and workers at identified highest-risk facilities.  Some HPEPH vaccination clinics MAY offer the bivalent vaccine, as availability allows. Vaccine clinics in Hastings and Prince Edward Counties will continue to offer monovalent vaccines (the same mRNA vaccines given as the primary series) for all eligible individuals until a steady supply of the bivalent vaccine is available.

Visit the HPEPH vaccine booking web page for details.
