transmission of SARS-CoV-2. After discussing anatomical and molecular differences between 36 the alveolar-capillary and syncytium-capillary barriers, the authors presented the well-37 considered hypothesis that the absence of caveolin expression in the syncytium is one of the 38 most important mechanisms preventing the transplacental passage of this virus (1) . Building on 39

their masterful analysis, we would like to extend the discussion to another important risk factor 40 for vertical transmission, namely viral load in blood. Wang 

Factors preventing 55 materno-fetal transmission of SARS-CoV-2

Detection of SARS-CoV-2 in 58 different types of clinical specimens

Clinical features of patients 61 infected with 2019 novel coronavirus in Wuhan

SARS-CoV-2 RNA detected in blood samples from patients with COVID-19 is not 65 associated with infectious virus
