Well-conducted studies (Medina-Lopes 1988, Bittencourt 1988, Amato Neto 1992) contradict other older ones that used dubious methodology (Mazza 1936) on the transmission by breast milk. The anecdotal and unproven cases of transmission that occurred during acute phase or while nipples were bleeding suggest it would better and less up-setting to perform a serological screening to the children at the end of lactation than avoiding breastfeeding contraindicarla in these cases (Paricio Talayero 2009).Given the overwhelming benefits of breastfeeding, it should not be recommended withholding of breastfeeding to Chagas Disease affected mothers like it is recommended by prestigious International Organizations (CLAP-PAHO-WHO, 2007, González-Tomé 2013). Chagas disease, either affecting the mother or infant, is compatible with breastfeeding. The mother should be treated whether acute or recent infection. Either the newborn or infant should be treated if it is congenitally infected. The treatments used (See tabs benznidazole and nifurtimox) are compatible with breastfeeding, both have been used without problems even in the neonatal period (García-Bournissen 2015, Vela-Bahena 2015), and spite they are directly administered to the infant or newborn (Altcheh 2011 , Chippaux 2013)
