Description

Note:
November 25, 2022: Due to a reporting cadence change for the Thanksgiving holiday, case rates for all Ohio counties will be calculated based on 13 days' worth of case counts in the COVID-19 Community Level data released on November 25, 2022, instead of the customary 7 days’ worth of data. This could lead to the COVID-19 Community level for all Ohio counties being overestimated; therefore, they should be interpreted with caution.
November 25, 2022: Due to the Thanksgiving holiday, CDC did not receive updated case data from the following jurisdictions: Rhode Island and Mississippi. As a result, case rates for all counties within these jurisdictions will be reported as 0 in the COVID-19 Community Level Data released on November 25, 2022. This could lead to the COVID-19 Community Levels being underestimated within these jurisdictions; therefore, they should be interpreted with caution.
This public use dataset has 11 data elements reflecting United States COVID-19 community levels for all available counties. The dataset contains the same values used to display information available on the COVID Data Tracker, and is updated weekly.
CDC looks at the combination of three metrics — new COVID-19 admissions per 100,000 population in the past 7 days, the percent of staffed inpatient beds occupied by COVID-19 patients, and total new COVID-19 cases per 100,000 population in the past 7 days — to determine the COVID-19 community level. The COVID-19 community level is determined by the higher of the new admissions and inpatient beds metrics, based on the current level of new cases per 100,000 population in the past 7 days. New COVID-19 admissions and the percent of staffed inpatient beds occupied represent the current potential for strain on the health system. Data on new cases acts as an early warning indicator of potential increases in health system strain in the event of a COVID-19 surge.
Using these data, the COVID-19 community level is classified as low, medium, or high.
COVID-19 Community Levels can help communities and individuals make decisions based on their local context and their unique needs. Community vaccination coverage and other local information, like early alerts from surveillance, such as through wastewater or the number of emergency department visits for COVID-19, when available, can also inform decision making for health officials and individuals.
See COVID-19 by County for more information.
For the most accurate and up-to-date data for any county or state, visit the relevant health department website. COVID Data Tracker may display data that differ from state and local websites. This can be due to differences in how data were collected, how metrics were calculated, or the timing of web updates.
