Infant Deaths Spike Amid Pandemic, New Study Reveals
A fresh study from Penn State College of Medicine has uncovered a worrying rise in sudden unexpected infant death (SUID) and sudden infant death syndrome (SIDS) during the COVID-19 pandemic—especially in 2021.
Respiratory Viruses Under Scrutiny
Published in JAMA Network Open, the research suggests a link between the comeback of seasonal respiratory viruses and the uptick in infant deaths. Lead researcher Emma Guare, a fourth-year medical student, said, “The cause of SUID is believed to be multi-factorial. We wanted to better understand the connection between infection and SUID, especially as endemic infection rates shifted during the pandemic.”
Sharp Increase in SUID and SIDS During 2021
The team sifted through CDC data from March 2018 to December 2021, spotting 14,308 SUID cases. Compared to pre-pandemic years, both SUID and SIDS rates surged by 9% and 10% respectively during the pandemic, peaking in 2021.
From June to December 2021, monthly SUID rates were 10% to 14% higher than pre-pandemic levels. This alarming spike coincided with an unexpected off-season outbreak of respiratory syncytial virus (RSV)—a virus that usually peaks in colder months.
Experts Warn Infections Could Raise Infant Risks
Co-author Dr Erich Batra, associate professor at Penn State, said, “It could be that infections increase the underlying vulnerability factors in infants, potentially contributing to SUID or SIDS.”
The researchers call for urgent further investigations into how infections affect infant deaths. They also stress the ongoing importance of safe sleep practices to protect babies.
While the study sheds light on the complex ties between respiratory infections and infant mortality, it underlines how multi-layered the issue of SUID and SIDS truly is.
