Over 12.8 mln children in U.S. infected with COVID-19

Over 12.8 million children have tested positive for COVID-19 since the onset of the pandemic, according to the latest report by the American Academy of Pediatrics (AAP) and the Children's Hospital Association.

Over 130,000 of these cases have been added in the past four weeks. Since the first week of last September, there have been nearly 7.8 million additional child COVID-19 cases, according to the report.

Children represented 19 percent of all COVID-19 cases in the United States, according to the report.

For the week ending March 31, children accounted for 16.6 percent of reported weekly COVID-19 cases.

There is an urgent 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.
