State-level reports are the best publicly available and timely data on child COVID-19 cases in the United States. The American Academy of Pediatrics and the Children’s Hospital Association are collaborating to collect and share all publicly available data from states on child COVID-19 cases.
As of September 9, nearly 5.3 million children have tested positive for COVID-19 since the onset of the pandemic. Over 243,000 cases were added the past week, the second highest number of child cases in a week since the pandemic began. After declining in early summer, child cases have increased exponentially, with nearly 500,000 cases in the past 2 weeks.
The age distribution of reported COVID-19 cases was provided on the health department websites of 49 states, New York City, the District of Columbia, Puerto Rico and Guam. Since the pandemic began, children represented 15.5% of total cumulated cases. For the week ending September 9, children were 28.9% of reported weekly COVID-19 cases (children, under age 18, make up 22.2% of the US population).
A smaller subset of states reported on hospitalizations and mortality by age; the available data indicate that COVID-19-associated hospitalization and death is uncommon in children.
At this time, it appears that severe illness due to COVID-19 is uncommon among children. However, there is an urgent need to collect more data on longer-term impacts of the pandemic on children, including ways the virus may harm the long-term physical health of infected children, as well as its emotional and mental health effects.
