“Based on Centers for Disease Control and Prevention (CDC) data, among children 5 to
<12 years of age there have been approximately 1.8 million confirmed and reported COVID-19 cases and 143 COVID-19-related deaths in the US through 14 October 2021. In this same age group, there have been 8622 COVID-19 related hospitalizations through
18 September 2021. This translates to cumulative incidence rates of approximately 6000 and 30 per 100,000 for confirmed COVID-19 cases and COVID-19-related hospitalizations, respectively, among children 5 to <12 years of age. The pediatric burden of COVID-19 likely exceeds that of seasonal influenza. Children can also suffer from post-acute sequelae after COVID-19. Through 04 October 2021, 5217 children in the US were diagnosed with Multisystem Inflammatory Syndrome (MIS-C), half of whom were children 5 to 13 years of age.”
