HIV/AIDS. HIV/AIDS damages cells of the immune system, making it difficult to fight infections and certain cancers. Women can pass the virus to their fetus during pregnancy; transmission also can occur during labor and giving birth or through breastfeeding.
Up to 20% of babies may get HIV infection from infected breast milk if the mother is not taking ART. However, breast milk contains nutrients that the newborn needs. It also protects the baby against some common childhood illnesses. Replacement feeding can increase the risk of infant death.
