• Description:
  What is already known about this topic? The SARS-CoV-2 B.1.617.2 (Delta) Variants is highly transmissible; however, whether it causes more severe disease in adults has been uncertain. ; What is added by this report? Analysis of COVID-NET data from 14 states found no significant increases in the proportion of hospitalized COVID-19 patients with severe outcomes during the Delta period. The proportion of hospitalized unvaccinated COVID-19 patients aged 18–49 years significantly increased during the Delta period. ; What are the implications for public health practice? Lower vaccination coverage in adults aged 18–49 years likely contributed to the increase in hospitalized patients during the Delta period. COVID-19 vaccination is critical for all eligible adults, including adults aged <50 years who have relatively low vaccination rates compared with older adults. ; Suggested citation for this article: Taylor CA, Patel K, Pham H, et al.
