Answer

Although prophylactic interventions have reduced vertical transmissions, cases of perinatal HIV transmission continue to occur. [10] This is largely because of missed opportunities for prevention, particularly among women who lack prenatal care or who are not being offered voluntary HIV counseling and testing during pregnancy. In many as 40% of the mothers of infants with perinatally acquired HIV infection, the HIV infection was not known before delivery.
