Insights
This study found no COVID-19 transmission from mothers to newborns during pregnancy or after birth. Breastfeeding rates were lower than anticipated in infants born to mothers with coronavirus disease 2019 (COVID-19).
Area of Science:
- Perinatology
- Infectious Diseases
- Neonatal Care
Background:
- Investigated clinical features of mothers with coronavirus disease 2019 (COVID-19) during pregnancy and delivery.
- Assessed potential vertical and horizontal transmission of COVID-19 to newborns.
- Monitored infants for one month post-discharge to evaluate transmission risks.
Purpose of the Study:
- To describe clinical characteristics of pregnant women with COVID-19.
- To evaluate vertical transmission of COVID-19 from mother to neonate.
- To assess horizontal transmission of COVID-19 in newborns post-hospital discharge.
Main Methods:
- Multicenter descriptive study across 16 Spanish hospitals.
- Reviewed medical records of 242 pregnant women with COVID-19 in their third trimester.
- Followed 248 newborns for one month to monitor for transmission.
Main Results:
- Mothers hospitalized with COVID-19 had higher rates of Cesarean sections (C-sections) and increased risk of premature delivery for their newborns.
- No cases of vertical or horizontal COVID-19 transmission were detected in the studied infants.
- Exclusive breastfeeding rates at discharge and one month were lower than expected.
Conclusions:
- No evidence of COVID-19 transmission during delivery or the first month of life was found in the study cohort.
- Lower-than-expected rates of exclusive breastfeeding were observed in newborns.
- Further research may be needed to understand breastfeeding practices in mothers with COVID-19.
Background:
Our aim was to describe the clinical features of mothers with coronavirus disease 2019 (COVID-19) infection during gestation or delivery, and the potential vertical transmission. We also wish to evaluate the possible horizontal transmission after hospital discharge, by means of a follow-up of all the newborns included at 1 month of age.
Methods:
This multicenter descriptive study involved 16 Spanish hospitals. We reviewed the medical records of 242 pregnant women diagnosed with COVID-19 from March 13 to May 31, 2020, when they were in their third trimester of pregnancy. They and their 248 newborn infants were monitored until the infant was 1 month old.
Results:
Caesarean sections (C-sections) were performed on 63 (26%) women. The initial clinical symptoms were coughing (33%) and fever (29.7%). Mothers hospitalized due to COVID-19 pathology had a higher risk of ending their pregnancy via C-section (P = 0.027). Newborns whose mothers had been admitted due to their COVID-19 infection had a higher risk of premature delivery (P = 0.006). We admitted 115 (46.3%) newborn infants to the neonatal unit, of those, 87 (75.6%) were only admitted due to organizational circumstances. No infants died and no vertical or horizontal transmission was detected. Regarding type of feeding, 41.7% of the newborns received exclusive breast-feeding at discharge and 40.4% at 1 month.
Conclusions:
We did not detect COVID-19 transmission during delivery or throughout the first month of life in the newborns included in our study. Exclusive breast-feeding rates at discharge and at 1 month of age were lower than expected.

Development of Immunocompetence
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
