What is the recommended method to reduce the risk of perinatal HIV transmission in patients with a viral load >1000 copies/mL?

The recommended method to reduce the risk of perinatal HIV transmission in patients with a viral load greater than 1000 copies/mL is a cesarean section prior to labor. This intervention is crucial because when a pregnant person has a high viral load, the likelihood of HIV transmission to the infant during the passage through the birth canal significantly increases.

Elective cesarean delivery prior to the onset of labor minimizes the infant's exposure to maternal blood and bodily fluids, which are the primary vectors for HIV transmission during the process of vaginal delivery. It is particularly emphasized for those with uncontrolled viral loads, as the goal is to lower the risk as effectively as possible.

In contrast, vaginal delivery in any form, including with the use of a condom or instrumental assistive devices like forceps or vacuum extractors, may still pose significant risks for transmitting the virus if the maternal viral load is high. These methods do not effectively limit the risk of exposure to the virus during the delivery process. Additionally, performing an episiotomy does not address the fundamental risk associated with high maternal viral loads and can even introduce further complications.
