COVID-19 was declared a pandemic by the WHO on 12 March 2020. Robust, population-based data describing COVID-19 during pregnancy and the neonatal period are critical to understand and manage this global threat in these groups.There are three key ways that SARS-CoV-2 could affect neonates:Vertical transmission of SARS-CoV-2 from mother to infant, which may lead to neonatal COVID-19.Horizontal transmission of SARS-CoV-2 in the neonatal period, potentially leading to neonatal COVID-19; this may occur from family contacts or nosocomial transmission in healthcare settings, such as neonatal units.Indirect effects on the newborn following maternal COVID-19 that impact pregnancy or labour and birth, leading to complications, such as preterm birth. This will include situations where the neonate is affected by, but does not contract, SARS-CoV-2.The impact of COVID-19 on neonates, as well as the importance of these different potential mechanisms of exposure, remains unclear. Vertical transmission of SARS-CoV-2 has yet to be definitively established; neonatal infection with the virus has been detected in the first days after birth to mothers with COVID-191; however, this could represent early horizontal transmission. Support for vertical transmission comes from serological testing following maternal COVID-19, which found SARS-CoV-2 IgM in umbilical cord blood2; however, SARS-CoV-2 viral RNA was not detected in these newborns, and the validity of current serological tests remains to be established.3 Nevertheless, neonates can be symptomatic with COVID-19 regardless of the mechanism of transmission. Although initial data indicated that the disease was less severe in children,4 approximately 10% of neonates and infants with COVID-19 develop severe or critical disease, a higher proportion than that in … ER -
