Studies Provide Additional Evidence About Risks Of Mother-To-Child SARS-CoV-2 Transmission

Fox News: Coronavirus infection unlikely in placenta, fetus: study
“The human placenta and fetus are unlikely to be infected with COVID-19 due to minimal expression of SARS-CoV-2-related proteins and receptors in the placenta, a new study says. … Researchers from the National Institutes of Health and Wayne State University, among others, published their findings on Tuesday in the journal eLife. … In the new findings, researchers noted that the placenta has a minimal expression of the ACE2 receptor and an enzyme the virus uses to enter a cell, called TMPRSS2. … Nevertheless, there is a possibility that the virus could infect the placenta through alternate entry routes while interacting with other proteins, ‘however, further research is required to test their participation in the pathogenesis of COVID-19,’ researchers wrote…” (Rivas, 7/14).

New York Times: Baby Was Infected With Coronavirus in Womb, Study Reports
“Researchers on Tuesday reported strong evidence that the coronavirus can be transmitted from a pregnant woman to a fetus. … Since the pandemic began, there have been isolated cases of newborns who have tested positive for the coronavirus, but there has not been enough evidence to rule out the possibility that the infants became infected by the mother after they were born, experts said. A recently published case in Texas, of a newborn who tested positive for Covid-19 and had mild respiratory symptoms, provided more convincing evidence that transmission of the virus during pregnancy can occur. … A study of the case was published on Tuesday in the journal Nature Communications…” (Belluck, 7/14).
