Pregnant women who are positive with COVID-19 when they give birth rarely transmit the virus to their newborns, according to a spate of new research. The reason: COVID-19 isn’t often found in a patient’s bloodstream.

As researchers have raced to understand the effects of COVID-19 on pregnancy and infants, these findings offer good news to expecting parents.

"Analyses show that infection among infants born to women with COVID-19 was uncommon,” said Kate Woodworth, a medical epidemiologist at the Centers for Disease and Prevention.
