Vertical Transmission of HIV: Preventing Transmission from Mother to Baby

Medical Implications

Worldwide, it is estimated that more than 40 million people live with HIV. While there are many medical advances in the realm of HIV care, specific co morbid health conditions may serve to only complicate the health of the HIV patient. Pregnancy, for example, can have adverse outcomes when there is a risk of maternal infection to the developing fetus. In women who suffer from HIV, the risk of viral transmission to the fetus is a significant complication of pregnancy and should be addressed early in pregnancy.

Preventing the transmission of HIV from mother to baby is important to fetal development. If, as a woman, you have been diagnosed with HIV, it is important to manage your family planning efforts carefully. Should pregnancy occur, an obstetrician who is specialized in at-risk pregnancies associated with HIV should be consulted.

While HIV can be transmitted during pregnancy, it can also be transmitted to a baby by way of vaginal delivery and through transmission during breastfeeding. In many cases, with the best protective measures of placental transmission, infants end up acquiring HIV from a mother by way of breast milk. The focus of the obstetrician, when managing an HIV at-risk pregnancy, will be to reduce the viral loads within the mother so as to prevent, as much as possible, the passing of the virus through the placenta.

In addition to your own aggressive treatment, your baby will also require aggressive treatment in the prevention of HIV. Both during gestation and after delivery, your physician may recommend IV administration of a HIV therapy during labor and then give the same prophylaxis to your infant immediately after birth and continuing for the first six weeks of life. To be effective, the dosing to your newborn will need to occur within the first four hours after birth. Therefore, a newborn with neonatal complications may experience a greater risk for missing this dosing when the healthcare team's focus falls upon other congenital complications. As the mother of a baby who is at-risk for HIV, it is important to understand this dosing protocol and follow-up with the healthcare team accordingly.
