In response, Walensky highlighted the difference between children being admitted to hospitals with the virus and because of the virus, noting that her agency so far has not seen evidence that Omicron causes increased severity in the youngest patients.
“Are they coming into the hospital because of COVID? Are they come in for some other reason? Are they getting routine screening and they’re detected with COVID? Those things are happening at the same time,” Walensky said.
“We are seeing a rise in hospitalizations, both because they’re coming in with COVID and for COVID,” she continued. “I would say we have not yet seen a signal that there is an increased severity in this age demographic.”
Walensky added that more efforts are needed to better understand exactly how the Omicron variant affects children and contributes to pediatric hospitalizations. She nonetheless encouraged parents to vaccinate their children.
“We have not yet seen that signal, but we will be looking for it for sure,” she said. “And I would say the best way to keep those children protected is to vaccinate them as they’re eligible and surround them by siblings and parents who were vaccinated themselves.”
In the study published on Dec. 31, researchers took a closer look at young patients who were hospitalized with COVID-19 in July and August 2020, when the Delta variant was the dominant variant of the virus in the United States. They found that most of those who suffered severe COVID-19 symptoms had underlying health conditions, especially obesity.
“Among patients aged 12–17 years, 61.4 percent had obesity,” according to the study, which covered 915 COVID-19 cases in 6 different U.S. hospitals, “60.5 percent of whom had severe obesity.”
