Fig. 1 — Newborn 1: On March 19, 2020, a 42-year-old woman (37 ^3/7 weeks of gestation) without known exposure to SARS-CoV-2 was admitted in our institution because of cough. Lung ultrasound showed diffuse interstitial lung disease. The RT-PCR on a nasopharyngeal swab was positive and treatment started. On March 26, an infant boy was delivered by cesarean section. His birth weight was 3,390 g and Apgar's scores were 9 to 10. The neonate had no symptoms and was immediately quarantined in the pediatric unit. On day 1 and 3 of life, RT-PCR tests on nasopharyngeal swabs turned negative. RT-PCR test on the placenta and umbilical blood were negative. The mother's breast milk tested with RT-PCR was result negative. The newborn was discharged on day 5 of life with the father who tested negative. On the same day, the mother was discharged and sent back home with a positive test. On day 15 of life, the newborn came back for the outpatient control. The newborn was healthy, with normal clinical examination. The mother decided to breastfeed him at home. Her breastmilk collected on day 11 to 14 had a negative RT-PCR test result. The newborn was tests with SARS-CoV-2 RT-PCR on nasal, pharyngeal, and rectal swab. The nasal swab resulted positive. Due to good conditions, the newborn was sent home with daily telemedicine updates to check his clinical status. Total 1 week later, the newborn is still in good clinical conditions. Newborn 2: On March 23, 2020, a 38-year-old woman (35 ^0/7 weeks of gestation)—exposed to both parents positive to SARS-CoV-2—was admitted in our institution because of cough. Lung ultrasound showed diffuse interstitial lung disease. The RT-PCR on a nasopharyngeal swab was positive and treatment started. During hospital admission, the woman required low-flow oxygen therapy for 48 hours. On March 28, due to fetal bradycardia, urgent cesarean section was performed. An infant boy was delivered by cesarean. His birth weight was 2,300 g and Apgar's scores were 8 to 9. The neonate immediately quarantined in the neonatal subintensive unit. On day 1 and 3 of life, RT-PCR tests on nasopharyngeal swabs turned negative. RT-PCR test on the placenta and umbilical blood were positive. The mother's breast milk collected during the first 5 days of newborn life tested positive on 3 out of 5 samples for SARS-CoV-2 RT-PCR test. The newborn was discharged on day 13 of life with the mother and father, both negative on nasopharyngeal swabs. On day 18 of life, the newborn came back for the outpatient control. The newborn was healthy, his weight was 2,800 g, with normal clinical examination. The father was feeding him with expressed breastmilk, which tested negative when collected on day 14 to 17. The newborn was tested with SARS-CoV-2 RT-PCR on nasal, pharyngeal and rectal swab, all negative. RT-PCR, real time-polymerase chain reaction; SARS-CoV-2, severe acute respiratory syndrome coronavirus 2.
