As COVID-19 cases skyrocket throughout the country, cases are also spiking in infants, children, and adolescents, and the group is now sharing more of the disease burden than ever recorded.

Cases in the young jumped 22 percent in the two weeks between October 29 and November 12, according to a new report from the American Academy of Pediatrics. The week ending on November 12 saw the largest one-week spike recorded in the pandemic, with 112,000 new cases.

There have now been more than 1 million cases in infants, children, and adolescents—collectively “children”—and the group is making up a larger proportion of cases than before. Children now make up 11.5 percent of total cases in the United States. At the end of July , children made up 8.8 percent of cases, up from 7.1 percent at the end of June and 5.2 percent at the beginning of June.
