New Research Offers Reassurance for Pregnant Patients

New Haven, CT – A recent study from Yale University provides important clarity on the long-term impact of COVID-19 on pregnancy, specifically regarding the placenta.

The study found that the virus does not persist in the placenta post-recovery.

Background on the Research
Yale researchers had previously demonstrated that SARS-CoV-2 can infect the placenta during an acute maternal illness, a condition known as COVID-19 placentitis. This condition is linked to inflammation and significant pregnancy complications.

Investigating Viral Persistence
In their new study, published in JAMA Network Open, the same team of researchers sought to answer a critical follow-up question: Does the virus remain in placental tissue after the mother has recovered from the infection?

The findings directly address a key concern for expectant mothers.

A Key Reassurance
Harvey Kliman, research scientist at Yale School of Medicine and senior author of the study, provided a clear conclusion. He stated that the findings reassure pregnant patients that the placenta will not become a reservoir for the virus after a COVID-19 infection during pregnancy.
