More than 121,000 new COVID-19 cases were reported among kids last week, another "substantial" increase from weeks prior, the American Academy of Pediatrics and the Children’s Hospital Association said in a report.

Last week, children represented 18% of all reported cases. Children represented 15% of cases the week prior.

Pediatric COVID-19-related hospital admissions have now equaled the most seen at any point of the pandemic.

Severe illness due to COVID-19 remains "uncommon" among children, the two organizations wrote in the report. In states which reported virus-related deaths by age, 0.00%-0.03% of all child COVID-19 cases resulted in death.

However, AAP and CHA warned that there is an urgent need to collect more data on long-term impacts on kids "including ways the virus may harm the long-term physical health of infected children, as well as its emotional and mental health effects."
