Omicron More Likely To Cause Upper Airway Infections Among Children Than Previous Covid Varieties, Study Says
Topline
The omicron variant is extra seemingly than different coronavirus variants to trigger higher airway an infection (UAI) amongst youngsters, which places them liable to coronary heart assault and different extreme problems, whilst the general threat for severe sickness for kids stays low, in accordance with a examine printed Friday by JAMA Pediatrics.

Key Info
The omicron variant typically causes much less extreme illness than the delta variant amongst all age teams, however is extra seemingly than delta to trigger UAIs like croup amongst youngsters, researchers affiliated with the College of Colorado College of Medication, Northwestern College Feinberg College of Medication and Stony Brook College Division of Biomedical Informatics decided.
UAI can put youngsters at explicit threat of cardiac arrest and different severe problems as a result of their small respiratory passageways are comparatively simply blocked, researchers mentioned.
The share of youngsters hospitalized with Covid-19 who had been additionally discovered to have UAI rose from 1.5% within the pre-omicron interval (March 1, 2020 to December 25, 2021) to 4.1% within the omicron interval (December 26, 2021 to February 17, 2022), in accordance with the examine.
Researchers additionally discovered that omicron tended to inflict UAI on youthful youngsters—the imply age of a hospitalized little one with Covid-19 and UAI fell from about 4 years and 5 months throughout the pre-omicron interval to about 2 years and one month throughout the omicron interval.
Total, 21.1% of youngsters hospitalized with each Covid-19 and UAI developed extreme illness requiring measures like inserting a tube into the lungs to help with respiratory.
Key Background
Measuring the relative severity of the omicron variant has posed a problem for scientists. Although analysis performed across the time omicron established its dominance within the U.S. indicated that it was merely a extra infectious and fewer extreme model of the delta variant, issues quickly emerged about omicron’s impact on youngsters. A examine printed February 15 by the Facilities for Illness Management and Prevention discovered that youngsters had been about 4 occasions as more likely to be hospitalized with Covid-19 throughout the omicron interval than throughout the delta interval. Scientists have proposed numerous explanations: as a result of youngsters are much less seemingly than adults to have Covid-19 immunity from vaccination or earlier an infection, they could be extra susceptible to omicron in some methods. Andrew Pavia, head of College of Utah Well being’s Division of Pediatric Infectious Illnesses, additionally suggested that omicron may infect the higher airways extra simply than the lungs, reducing the chance of extreme lung-based sicknesses however growing the chance of higher respiratory sicknesses, to which youngsters are particularly susceptible. Whereas the speed of Covid-19-caused UAI amongst youngsters is just not “overwhelmingly excessive,” additional examine might assist information remedy for younger sufferers, wrote the authors of the JAMA Pediatrics examine.
Tangent
Within the U.S., Covid-19 vaccines have been authorized for individuals age 5 and up. Regardless of this, 30% of individuals within the U.S. age 5 and up have but to be totally vaccinated, in accordance with the CDC. Youthful persons are typically much less more likely to be vaccinated than older individuals.
Massive Quantity
12.87 million. That’s the cumulative variety of little one Covid-19 circumstances reported within the U.S. as of April 7, in accordance with the American Academy of Pediatrics.
Contra
Whereas the omicron variant has elevated an infection charges amongst youngsters, the chance of extreme sickness amongst youngsters stays extraordinarily low. Knowledge from the CDC and the JAMA Pediatrics examine point out {that a} little one’s threat of being hospitalized with Covid-19 is roughly 1 in 14,085, whereas a baby’s threat of being hospitalized with Covid-19 and creating a UAI and extreme signs is roughly 1 in 10 million. The danger of extreme sickness amongst youngsters hospitalized with Covid-19 has additionally fallen to roughly 3.4% throughout the omicron interval, down from 38.8% throughout the pre-omicron interval, in accordance with the JAMA Pediatrics examine. Whereas little one deaths within the JAMA Pediatrics examine had been too uncommon to be exactly quantified, an American Academy of Pediatrics survey of knowledge from 46 states discovered that youngsters accounted for between 0% and .27% of cumulative Covid-19 deaths in every state, with three states reporting no little one Covid-19 deaths.
