More troubling news regarding COVID-19 has emerged, as a new study indicates a significant rise in severe croup cases among infants and young children linked to the Omicron variant.
The study, published in the peer-reviewed journal Pediatrics, reveals that while Omicron is considered less severe than previous strains, it is substantially more contagious and seems to be associated with a higher incidence of laryngotracheobronchitis, commonly known as croup, in younger populations. Conducted at a Massachusetts hospital, the research highlighted that a staggering 81% of the 75 children diagnosed with COVID-19-related croup were treated during the Omicron wave.
Croup, a viral infection affecting the upper respiratory tract, leads to symptoms such as a distinctive “seal bark” cough, fever, and difficulty breathing, predominantly impacting children. In severe cases, it can be life-threatening. The study’s findings corroborate anecdotal reports from around the globe suggesting a connection between the Omicron variant and an increased risk of this respiratory infection in children.
Researchers noted that while it’s unclear why Omicron is more likely to cause croup, it may be because other variants, like Delta, primarily affected the lower respiratory tracts, whereas Omicron tends to focus on the upper airways. The study also revealed that hospitalization rates and the need for repeated treatments indicate a more severe form of croup compared to other viral causes.
Dr. Emily Harper, one of the study’s authors, emphasized that most cases can be managed at home or in outpatient settings with treatments like dexamethasone. However, the higher hospitalization rates and the average of six doses of dexamethasone and eight nebulizer treatments for hospitalized children suggest that COVID-19 may induce more severe manifestations of croup than other viruses. Further investigation is needed to determine optimal treatment strategies for these young patients.
It is essential to note that a diagnosis of croup does not necessarily imply a COVID-19 infection. However, Dr. Samuel Turner, the chief of Pediatric Medicine at the overseeing hospital, recommended testing for COVID-19 if croup is suspected, especially if there has been recent exposure.
In light of these findings, staying current with vaccinations and boosters is crucial, as well as regular testing to help prevent complications linked to COVID-19-associated croup. For more on this topic, you can check out our other post here.
