Simply over 80% of the circumstances occurred after Omicron turned the dominant coronavirus variant in the USA.

“There was a really clear delineation from when Omicron turned the dominant variant to after we began seeing an increase within the variety of croup sufferers,” Brewster mentioned.

Not one of the youngsters died, however 9 (12%) had been admitted to the hospital and 4 of these sufferers required intensive care.

Earlier than COVID-19, fewer than 5% of youngsters with croup had been hospitalized, and solely 1-3% of hospitalized sufferers required intubation, in response to the research.
