These results coincide with these located in earlier studies (1, 7, 246), while a really low price of good milk samples (4) or isolated case reports (271) have also been published. This information is essential as neonatal infection by SARS-CoV-2 is uncommon and normally asymptomatic (324).The lack of viral RNA in breastmilk supports its security, and it’s in accord with recent epidemiological data, as various modest observational studies reported on the absence of infection in infants fed by breastmilk of SARS-CoV-2 constructive woman (35, 36) or inadvertently fed with SARS-CoV-2 RNA-positive milk (29). SARS-CoV-2 RNA seems to be widespread on surfaces from COVID-19 patient rooms (37) and, also, on the breast skin of lactating mothers (three). This suggests that milk samples may become contaminated with viral RNA when a mother and/orFIGURE 2 Concentration (log) of cytokines in breastmilk of study group women in accordance with the moment in which the nasopharyngeal test becomes damaging (pooling samples obtained at weeks 1 and five). Cytokine concentrations had been substantially larger in breastmilk samples of mothers whose RT-PCR remained constructive at postpartum week 3 (dark blue box) compared.
