Perinatal hepatitis B guidelines for prenatal care

1. Screen every pregnant woman for HBsAg early in each pregnancy.

As Centers for Disease Control and Prevention (CDC) and American College of Obstetricians and Gynecologists (ACOG) recommend. Repeat HbsAg testing late in pregnancy if the woman is HBsAg negative and at high risk of hepatitis B infection (e.g., injection drug user, infected with other sexually transmitted diseases, has multiple sexual partners).

2. Report every HBsAg-positive pregnant woman within 3 business days.

WAC 246-101-101 requires providers report this condition. Health Department staff provide case management and follow-up services for infants and family members.

3. Counsel each HBsAg-positive pregnant woman.

  • How hepatitis B spreads.
  • How to prevent hepatitis B.
  • Need to get medical follow-up with a liver specialist.
  • Infant must get:
    • HBIG and hepatitis B vaccine within 12 hours of birth. Two additional doses of hepatitis B vaccine at 1–2 months old and 24 weeks old.
    • Post-vaccine screening at 9–12 months old to confirm the baby is protected. Or 1–2 months after final dose of vaccine series, if the series was delayed. If the series was delayed, post-vaccine serology should be collected 1–2 months after the final dose.
  • Household members and sexual partners need to be screened for hepatitis B. If susceptible, get vaccine at 0 months, 1–2 months and 4–6 months intervals.

4. Report every HBsAg-positive woman to the hospital prior to admission for delivery.

To ensure the infant gets appropriate post-exposure care.
