Overview
HDV infection requires the person to be co-infected with HBV, therefore, vaccination against hepatitis B also confers immunity against hepatitis D. Since a vaccine against hepatitis D for patients infected with HBV is not available, these individuals should prevent superinfection by avoiding risk behaviors, such as: contact with blood from infected individuals, and sharing of sharp objects.
Prevention
In order to be infected with hepatitis D, a patient must be previously infected with HBV (superinfection) or be infected by HBV at the same moment of infection with HDV (coinfection). The best prevention against hepatitis D is vaccination with hepatitis B vaccine.[1]
Since a vaccine against hepatitis D is not available for patients who are already infected with HBV, the best course of action to prevent superinfection in these patients is to avoid risk behaviors, such as: [1]
- Sex with an infected partner
- Contact with the blood of an infected person
- Sharing of needles, syringes, razors, or toothbrushes with an infected person
- Healthcare workers who deal with sharp objects, potentially with blood from infected patients should take extra caution
It is essential to vaccinate the family members of patients who are infected with HBV and HDV. Despite the common parenteral transmission of HDV, the virus has also been noted to be transmitted among family members, which justifies extraordinary precautions in these families.[2]
HIV Infected Patients
HIV infected persons may not develop protective immunity after receiving the hepatitis B vaccine. Hence, they remain at risk for infection with HBV and HDV.[3]
Pregnant Patients
Pregnant women should be screened for hepatitis B infection. If a woman is at risk for HBV infection, she should be vaccinated. The current recommendations of the American College of Pediatrics and the Centers for Disease Control and Prevention are that all infants be immunized against hepatitis B.[4]
