CONCLUSIONS
The neonatal case in our report, with an elevated IgM level and a manifestation of viral pneumonia in chest CT, highlights the possibility of transplacental transmission from the infected mothers to their fetuses. We suggest that all COVID-19 pregnant women should be closely monitored during pregnancy, and a careful examination of the neonate born to an infected mother should be performed to provide more information about vertical transmission of SARS-CoV-2.
