CDC COVID-19 by County

The CDC's COVID-19 by County hospital admissions levels measure the impact of COVID-19 illness on health and health care systems. Whether you're at home or planning to travel, check the current COVID-19 status in your area or your destination. This information will help you make informed decisions about recommended prevention measures for yourself and your community. Hospital admission level maps, charts, and data provided by CDC are updated every Thursday by 8 p.m. ET.

County-level hospital data, including new hospital admissions levels, are derived using calculations performed at the Health Service Area (HSA) level. An HSA is defined by CDC’s National Center for Health Statistics as a geographic area containing at least one county that is self-contained with respect to the population’s provision of routine hospital care. Every county in the United States is assigned to an HSA, and each HSA must contain at least one hospital. Data presented represent admissions and bed use among hospitals within the selected HSA. Alaska's boroughs/census areas are divided among four HSAs. Data from all hospitals in an HSA are added together to calculate the hospitalization metrics.
