Perinatal Hepatitis B Prevention Program

What is the Perinatal Hepatitis B Prevention Program (PHBPP)?

The PHBPP is a tracking and reminder program for infants and household contacts of pregnant women who have hepatitis B (HBsAg-positive).

What is the goal of the PHBPP?

The main goal of the PHBPP is to reduce the incidence of hepatitis B in infants born to women with hepatitis B.

How is this goal achieved?

First, HBsAg-positive pregnant women must be identified:

  • All women should be screened for hepatitis B (HBsAg) during each pregnancy.
  • Women who test negative for HBsAg early in their pregnancy but who are at increased risk for hepatitis B should be screened again at the time of delivery.

All HBsAg-positive pregnant women should be reported to the health department during their pregnancy and at the time of their delivery.

A follow-up system is in place to help assure that infants born to HBsAg-positive women receive appropriate post-exposure prophylaxis.

Additionally, all household and sexual contacts of pregnant women with hepatitis B should be identified, and

  • Susceptible contacts should receive the 3-dose series of hepatitis B vaccine.
  • Any contacts with a recent exposure may also need hepatitis B immune globulin (HBIG), if a substantial exposure to an HBsAg-positive woman has occurred within the last 14 days.

What is the appropriate post-exposure prophylaxis for infants born to HBsAg-positive women?

HBIG and the first dose of hepatitis B vaccine given within 12 hours of birth 2 additional doses of hepatitis B vaccine, given at 1-2 months of age and 6 months of age (dose 3 should not be given before infant is 6 months of age).

What about follow-up blood testing of these infants?

Infants born to HBsAg-positive women should be screened for HBsAg (to see if they have hepatitis B) and anti-HBs (to see if they have adequate antibody (are protected) against hepatitis B).

This follow-up testing should be done 3 to 9 months after dose #3 of hepatitis B vaccine (at 9-15 months of age).

How and when do I report a pregnant women who has hepatitis B (HBsAg-positive)?

Hepatitis B in pregnant women is a legally notifiable condition and should be reported within one working day to the health department.

All pregnant women who are HBsAg-positive should be reported to the health department as early in pregnancy as possible.

Reporting of an HBsAg-positive pregnant woman to Washoe District Health Department can be done by:

  • Faxing a copy of the HBsAg-positive test results to the confidential fax at (775) 328-3764, or
  • Faxing a completed Nevada State Health Division "Confidential Case Report" form to the confidential fax at (775) 328-3764, or
  • Calling Communicable Disease Control at (775) 328-2447.
