The Centers for Disease Control and Prevention (CDC) released an MMWR on the Changing Age Distribution of the COVID-19 Pandemic in the U.S. between May and August, 2020. A key finding is that during June-August 2020, COVID-19 incidence was highest in persons aged 20-29 years, who accounted for >20% of all confirmed cases. Strict adherence to community mitigation strategies and personal preventive behaviors by younger adults is needed to help reduce infection and subsequent transmission to persons at higher risk for severe illness.
