My wife is hbv infected. can a hepatitis b virus infected woman give birth to healthy child?

Yes: Those who acquired the germ before pregnancy can still pass it on to their newborn.However, infant vaccination at birth with simultaneous administration of Hepatitis B Immune Globulin can often prevent transfer of the germ during the birth process. Consult with your OB and the pediatrician involved so the material will be available at delivery.
