Cases of transmission of covid-19 from pregnant women to their babies are rare and should not cause excessive concern, experts said Tuesday after a study study was published suggesting that the new coronavirus may cross the placenta.
The study, published in the journal « Nature Communications“He described a case in France where the virus causing covid-19 was found in the blood of a baby born prematurely to a 23-year-old mother who was diagnosed with pandemic disease in March.
Detection of the virus in placental tissue, as well as in the blood of mother and baby, suggests that “transplacental transmission of SARS-CoV-2 may be possible“Wrote the doctors who detailed the case. They added, however, that more studies would be needed to confirm this.
Speaking to Reuters, Marian Knight of the University of Oxford (Great Britain) said the case was interesting, but should not be a major concern for pregnant women.
“Among the thousands of babies born to mothers with SARS-CoV-2 infection, very few have been reported to also have a positive result, about 1-2%. It is not yet clear if the virus passes through the placenta; This report provides evidence that you can. “
Both the mother and the baby in the French case recovered well and were discharged from the hospital.
