Babies born to mothers with COVID-19 only rarely suffer from effects of the virus, a new study suggests. These newborns generally do well in the six to eight weeks after birth, but more are admitted to the neonatal intensive care unit (NICU) if their mothers had COVID-19 in the two weeks before delivery. Of more than 200 babies studied, complications including preterm birth and NICU admission didn't differ among mothers with and without COVID-19. No pneumonia or lower respiratory infections were reported through 8 weeks of age.
