Low rates of mother-to-child HIV transmission through breastmilk of women on antiretroviral therapy.
In the MITRA Plus trial in Tanzania, mothers received triple therapy from late pregnancy until the infant was six months old and/or breastfeeding had stopped (therapy was continued where the mother needed it for her own health). Of the 441 infants alive at six months, 5% had become infected with HIV, but less than one in five of these was infected between week 6 and 6 months. This suggests that the antiretroviral therapy proved highly protective during the breastfeeding period. (2) In the ongoing AMATA study in Rwanda, seven children were found to be HIV-infected, of whom six were infected at birth. Thus, only one infection (0.6%) has occurred during the breastfeeding period out of 174 breastfeeding women on antiretroviral therapy. Since the mother concerned had detectable viral load when she was tested, investigators believe she may have discontinued the medication. (3)
