Mother-to-Child Transmission (MTCT) Audio (En español)

Also known as: Maternal-Child Transmission, Perinatal Transmission

When an HIV-infected mother passes HIV to her infant during pregnancy, labor and delivery, or breastfeeding (through breast milk). Antiretroviral (ARV) drugs are given to HIV-infected women during pregnancy and to their infants after birth to reduce the risk of mother-to-child transmission (MTCT) of HIV.
