By Pooja Toshniwal PahariaApr 12 2023Reviewed by Lily Ramsey, LLM In a recent study published in the Pediatrics Journal, researchers assessed the incidence rate of severe acute respiratory syndrome coronavirus 2 infections pre- and post-SARS-CoV-2 Omicron variant of concern dominance among infants born to SARS-CoV-2-positive mothers.
Omicron, although highly transmissible, causes less severe infections among the general public. However, a rise in neonatal hospitalizations has been reported, during the Omicron wave, compared to prior VOC waves. Data of infants aged below six months born to SARS-CoV-2-positive mothers in 2020-2021, as documented by the surveillance for emerging threats to pregnant individuals and infant network of six jurisdictions, regulated by the United States Centers for Disease Control and Prevention .
Further, the team performed a sub-analysis by limiting the analysis to neonates birthed to mothers diagnosed with COVID-19 before 5 December 2021. The US CDC reviewed the survey procedure, weighting, and population-level rectifications concordant with the CDC policies and federal laws. The findings indicated that the elevated COVID-19 incidence rates were not a result of greater perinatal SARS-CoV-2 transmission.
