Two cases of HIV transmission through breastfeeding in mothers with undetectable viral load reported

“Two cases of HIV transmission from mother to infant during the breastfeeding period when mothers had an undetectable viral load have been reported by PROMISE, a large international study of the effectiveness of antiretroviral treatment in preventing vertical HIV transmission… Earlier this year an international group of researchers called for more research to determine if HIV can be transmitted through breast milk even if the breastfeeding mother has an undetectable viral load in blood. Swiss doctors have argued that pregnant women with HIV should be informed of the uncertain evidence about the risk of transmission during breastfeeding, and rather than being prohibited from breastfeeding while taking antiretroviral drugs, should be supported to breastfeed safely through regular viral load testing and education about factors that might increase the risk of transmission, such as mastitis.”
