It also notes that invasive obstetric procedures can increase the risk of mother-to-child transmission by exposing the fetus to more infected maternal blood and secretions. Finally, it reports that a cesarean section before labor and membrane rupture can reduce transmission risk by 50-80% compared to other delivery modes for women not on antiretroviral therapy or only on ZDV, but there is no evidence of benefit for
