Fetal coronavirus infection is possible, study suggests
A small study strengthens evidence that a pregnant woman infected with the coronavirus might be able to spread it to her fetus.
Researchers from Italy said Thursday that they studied 31 women with COVID-19 who delivered babies in March and April. They found signs of the virus in several samples of umbilical cord blood, the placenta and, in one case, breast milk.
It merits more study, especially of women who are infected earlier in their pregnancies than these women.
Dr. Ashley Roman, a pregnancy specialist at NYU Langone Health, said she and colleagues also detected viral particles on the fetal side of the placenta in several of the 11 cases they examined. The new report adds evidence that in-womb transmission is possible, but it seems rare and to not cause serious problems in the infants, she said.
"The most important thing that pregnant women need to know is it's important to socially distance. It's important to wear a mask, wash their hands," Roman said. "Women don't need to be cut off from society entirely, but they should be concerned about the impact of getting COVID on their own health during pregnancy."
