    SARS-CoV-2 infection during pregnancy is associated with placental inflammation and adverse outcomes, including stillbirth.

  • 2

    The study examined placental tissue from women with acute COVID-19 placentitis and those recovered from SARS-CoV-2 infection.

  • 3

    No detectable SARS-CoV-2 protein or RNA was found in placental tissue from recovered cases, even with inflammatory lesions present.

  • 4

    Placental injury was observed in cases resulting in stillbirth, but without evidence of ongoing viral infection.

  • 5

    The findings suggest that postacute placental pathology may be due to immune-mediated processes rather than viral persistence.
