Final answer:
The risk of transmission from mother to child can be significantly reduced by the use of antiretroviral medication during pregnancy and delivery.
Step-by-step explanation:
The correct answer is C. The risk of transmission from mother to child can be significantly reduced by the use of antiretroviral medication during pregnancy and delivery.
The perinatal transmission of HIV refers to the transmission of the virus from an infected mother to her child during pregnancy, childbirth, or breastfeeding.
Antiretroviral medications are drugs that can suppress the replication of the HIV virus in the body. When a pregnant woman with HIV takes antiretroviral medications, it can greatly reduce the amount of virus in her blood, minimizing the risk of transmission to the baby. These medications can also be given to the infant after birth to further reduce the risk of transmission.
