What is already known about this topic?
COVID-19 monitoring will remain a public health priority after the U.S. public health emergency declaration expires on May 11, 2023.
What is added by this report?
Assessment of available surveillance indicators found that COVID-19 hospital admission levels were concordant with COVID-19 Community Levels. COVID-19–associated hospital admission rates lagged 1 day behind case rates and 4 days behind percentages of COVID-19 emergency department visits and positive SARS-CoV-2 test results. National Vital Statistics System trends in the percentage of COVID-19 deaths strongly correlated with, and were 13 days timelier, than aggregate death count data.
What are the implications for public health practice?
Rates of COVID-19–associated hospital admission and the percentages of positive test results, COVID-19 emergency department visits, and COVID-19 deaths are suitable and timely indicators of trends in COVID-19 activity and severity.”
