<P> HIV can be transmitted from mother to child during pregnancy , during delivery , or through breast milk , resulting in the baby also contracting HIV . This is the third most common way in which HIV is transmitted globally . In the absence of treatment , the risk of transmission before or during birth is around 20 % and in those who also breastfeed 35 % . As of 2008 , vertical transmission accounted for about 90 % of cases of HIV in children . With appropriate treatment the risk of mother - to - child infection can be reduced to about 1 % . Preventive treatment involves the mother taking antiretrovirals during pregnancy and delivery , an elective caesarean section , avoiding breastfeeding , and administering antiretroviral drugs to the newborn . Antiretrovirals when taken by either the mother or the infant decrease the risk of transmission in those who do breastfeed . However , many of these measures are not available in the developing world . If blood contaminates food during pre-chewing it may pose a risk of transmission . </P>
