About Pregnancy and HIV


One of Project ARK’s most significant achievements has been the successful reduction of mother-to-child HIV transmission across the MO/IL bi-state service region. Our program has partnered with regional HIV testing sites to create a well-established system for HIV-infected pregnant women to be referred to our Part D program for care and follow-up.  Our program includes both Washington University and Saint Louis University medical providers and provides intensive medical care coordination for the mother and infant to ensure their linkage and retention in HIV and obstetric medical care. A team comprised of a nurse and case manager work in partnership with the mother and infant’s medical providers (Washington University, Saint Louis University or other) to provide education and address barriers to care which are identified.  As a result of these collaborative efforts, perinatal HIV infection has nearly been eradicated in the region.

The Perinatal HIV Working Group is a multidisciplinary group including physicians, nurse practitioners, nurses and social workers established to work toward elimination of perinatal HIV transmission at Barnes-Jewish Hospital, St. Louis, and the surrounding area. We oversee HIV testing in pregnant patients cared for at Barnes-Jewish Hospital and Washington University, and cumulatively provide care to all HIV infected pregnant individuals delivering at Barnes-Jewish Hospital and give consultation concerning patients in the St. Louis Region.

When HIV positive women take medication during pregnancy and labor and the baby takes medication for 6 weeks after delivery, risk of infection is less than 1-2%. It is most effective to start medication early in the pregnancy, however, taking medication at any point can provide some protection to your baby.
