New research suggests the coronavirus can invade and destroy the placenta and lead to stillbirths in infected women.
Lead author Dr. David Schwartz, an Atlanta pathologist, said other infections can infiltrate the placenta and cause stillbirth, typically by infecting and damaging the fetus. A recent example is Zika virus.
The placenta is an organ that forms and attaches to the womb during pregnancy. It connects with the umbilical cord, providing oxygen and nourishment from the mother’s bloodstream. The virus likely reached the placenta through the bloodstream, attaching to susceptible cells and causing protein deposits and an unusual form of inflammation that blocked blood flow and oxygen. That in turn led to placenta tissue death and suffocation, the researchers said.
