Neonatal SARS-CoV-2 Infection: Practical Tips

Area of Science:

• Virology
• Infectious Diseases
• Neonatology

Background:

• The emergence of SARS-CoV-2 caused a global pandemic, leading to COVID-19.
• COVID-19 presents with a wide range of symptoms, from mild to severe respiratory illness.
• Infants and children generally experience a more favorable clinical course compared to other age groups.

Purpose of the Study:

• To review the biology and pathogenesis of SARS-CoV-2, particularly in pregnancy and neonates.
• To detail the clinical presentation of COVID-19 in newborns and young infants.
• To summarize current international recommendations for managing neonates with or at risk of SARS-CoV-2 infection.

Main Methods:

• Literature review of SARS-CoV-2 biology, pathogenesis, and clinical manifestations.
• Focus on studies concerning pregnancy, fetal transmission, and neonatal outcomes.
• Synthesis of international clinical care guidelines for perinatal and neonatal COVID-19 management.

Main Results:

• No clear evidence of vertical or intrauterine SARS-CoV-2 transmission has been found.
• Maternal SARS-CoV-2 positivity does not necessitate C-section, rooming-in, or contraindicate breastfeeding.
• Neonates and infants typically present with a milder clinical course of COVID-19.

Conclusions:

• The review provides an updated overview of SARS-CoV-2 in the perinatal and neonatal context.
• Current evidence suggests limited risk for vertical transmission and favorable outcomes in infants.
• Recommendations focus on safe clinical management practices for neonates and their mothers.
