Nearly 238,000 of these cases have been added in the past four weeks. Approximately 6.9 million reported cases have been added in 2022, according to the report, Xinhua reported.
For the week ending Sept. 29, 39,200 child COVID-19 cases were reported, and child COVID-19 cases accounted for 15.2 percent of all infections reported in the United States.
But the reported cases are likely a "substantial undercount" of COVID-19 cases, according to the report.
There is a need to collect more age-specific data to assess the severity of illness related to new variants as well as potential longer-term effects, said the AAP.
"It is important to recognize there are immediate effects of the pandemic on children's health, but importantly we need to identify and address the long-lasting impacts on the physical, mental, and social well-being of this generation of children and youth," said the AAP
