Covid-19: Study finds mother-to-baby infection rate low, indirect risk exists

Although mother-to-newborn transmission of coronavirus is uncommon, newborns of expectant moms with COVID-19 can nonetheless endure indirect opposed well being dangers because of worsening maternal sickness as a result of illness, a examine says.

Beth Israel Deaconess Medical Center (BIDMC), Brigham, Women’s Hospital, Boston Children’s Hospital and Massachusetts General Hospital reveal that ‘ours is the primary examine to dive into the risk elements for mother-to-newborn SARS-CoV-2 transmission.”

“We expected the mode of delivery and/or the degree of maternal illness to increase the risk of newborn infection, but were surprised to find that this was not the case.” Examining neonatal outcomes in the course of the first month of life for infants born at 11 hospitals that signify roughly 50 % of all births in Massachusetts, the workforce recognized 255 neonates delivered between March 1-July 31, 2020, to moms with a latest optimistic SARS-CoV-2 take a look at outcome. The researchers used the American Academy of Pediatrics’ National Registry for Surveillance and Epidemiology of Perinatal COVID-19 Infection complemented by a Massachusetts-specific Registry.

Out of the 255 neonates studied, 88.2 % have been examined for SARS-CoV-2, and solely 2.2 % had optimistic outcomes, as per the examine.

However, whereas infection charges amongst newborns have been comparatively low, worsening maternal sickness accounted for 73.9 % of preterm births. Premature beginning can usually result in acute and continual issues, together with respiratory misery, continual well being issues and developmental disabilities.

“We found that of babies born to mothers with COVID-19, very few babies tested positive,” stated senior creator Mandy Brown Belfort, MD, MPH, Director of Clinical Research within the Department of Pediatric Newborn Medicine at Brigham and Women’s Hospital and Associate Professor of Pediatrics at Harvard Medical School.

“Instead, the adverse health impact of maternal COVID-19 on the newborn was from preterm delivery, usually prompted by a mother’s worsening illness. Our findings support the need for thoughtful and collaborative decision-making around delivery timing in the setting of maternal COVID-19 illness.” Other indicators of opposed toddler well being outcomes the researchers included of their evaluation included low beginning weight or very low beginning weight, want for supply room resuscitation, size of hospital keep and healthcare utilisation for non-routine visits inside a month after discharge, the examine stated.

“This observation that newborns of socially vulnerable mothers were five times more likely to have COVID-19 highlights that health disparities are very complex and extend beyond race, ethnicity and language status,” stated Asmenia Angelidou, teacher in pediatrics at Harvard Medical School.

“Social vulnerability likely affects health and immunity and our study supports further research in this area. Reallocation of resources to socially vulnerable communities could go a long way in decreasing human suffering and economic loss during disease outbreaks.” The authors recommend additional analysis on perinatal viral transmission ought to embody girls with COVID-19 early in being pregnant to be able to establish the window of highest susceptibility to the virus for mom and child throughout being pregnant. Conversely, future analysis together with pregnant girls immunised towards COVID-19 is necessary to tell the optimum window for maximal neonatal safety after maternal immunization, they stated.

“While the low rates of neonatal infection we observed are reassuring, it is important that providers remain vigilant,” Angelidou stated.

“Even during public health emergencies like the ongoing pandemic, providers need to carefully monitor newborns for atypical signs of the illness, while also trying to avoid unnecessary premature deliveries that pose inherent risks for both mother and child,” she stated.
