In a survey of data published on the health department websites of 49 states, New York City, the District of Columbia, Puerto Rico and Guam, a total of 624,890 child cases of COVID-19 were reported from the start of the pandemic through Sept. 24, or 10.5% of all cases in states reporting infections according to age.

A smaller subset of states reported hospitalizations and mortality by age. The data from those states indicate "COVID-19-associated hospitalization and death is uncommon in children," according to the survey.
