Infants born to those who tested positive for COVID-19 during pregnancy may have neurodevelopmental issues after birth, according to preliminary findings from two separate studies out of the U.S. and Spain.
Infants born to those who tested positive for COVID-19 during pregnancy may have neurodevelopmental issues after birth, according to new preliminary findings from two separate studies out of the U.S. and Spain.on June 9, looked at 7,772 infants delivered during the pandemic between March and September 2020 at six hospitals in Massachusetts, 222 of whom had prenatal exposure to SARS-CoV-2.
“Our findings identifying an association between prenatal SARS-CoV-2 exposure and neurodevelopmental diagnoses at 12 months are consistent with a large body of literature including human and animal studies linking maternal viral infection and maternal immune activation with offspring neurodevelopmental disorders later in life, some of which can be foreshadowed as early as the first year of life,” the authors wrote in the study.
The scientists also found that 14.4 per cent of those who tested positive during their pregnancy gave birth prematurely, or before 37 weeks, compared with 8.7 per cent of those who did not get infected. Previous studies elsewhere have also noted a higher risk of preterm birth among those who caught COVID-19 while pregnant.
The study noted some limitations to its research, a key element being the short-time frame of the analysis. Hormonal and other biochemical analyses, movement responses, and other tests were conducted during and after pregnancy on the parent, while infant tests included measuring movements and behaviours according to the Neonatal Behavioral Assessment Scale .
