Lactancia materna en mujeres con COVID-19: falta de evidencia sobre la presencia de SARS-CoV-2 en la leche materna Aleitamento materno em mulheres com COVID-19: falta de evidência da presen?a da SARS-CoV-2 no leite materno

摘要

A rapid systematic review was carried out to evaluate the current evidence related to the presence of SARSCoV-2 in breast milk from pregnant women with COVID-19. Eight studies analyzing the presence of SARS-CoV-2RNA in the breast milk of 24 pregnant women with COVID-19 during the third trimester of pregnancy werefound. All patients had fever and/or symptoms of acute respiratory illness and chest computed tomographyimages indicative of COVID-19 pneumonia. Most pregnant women had cesarean delivery (91.7%) and twoneonates had low birthweight ( 2 500 g). Biological samples collected immediately after birth from upperrespiratory tract (throat or nasopharyngeal) of neonates and placental tissues showed negative results for thepresence SARS-CoV-2 by RT-PCR test. No breast milk samples were positive for SARS-CoV-2 and, to date,there is no evidence on the presence of SARS-CoV-2 in breast milk of pregnant women with COVID-19. However, data are still limited and breastfeeding of women with COVID-19 remains a controversial issue. There areno restrictions on the use of milk from a human breast milk bank.
