COVID-19 Reported Patient Impact and Hospital Capacity by Facility

This data source provides various measures of COVID-19 burden on patients and healthcare in the US at the facility (e.g. hospital) level. It is a mirror of the “COVID-19 Reported Patient Impact and Hospital Capacity by Facility” dataset provided by the US Department of Health & Human Services via healthdata.gov.

It is a mirror of the “COVID-19 Reported Patient Impact and Hospital Capacity by State Timeseries” and “COVID-19 Reported Patient Impact and Hospital Capacity by State” datasets provided by the US Department of Health & Human Services via healthdata.gov. The latter provides more frequent updates, so it is combined with the former to create a single dataset which is as recent as possible.

Google Symptoms Search Trends

Google's [COVID-19 Search Trends symptoms dataset](http://goo.gle/covid19symptomdataset) reflects the relative volume of Google searches for a broad set of symptoms, signs and health conditions. This source includes signals for 7 symptom sets: 6 sets of COVID-related symptoms, and 1 set of control symptoms unrelated to COVID-19. Because of the way this dataset is constructed, values are comparable across signals in the same location, but not across geographic regions, even within the same signal. Use caution in any geographic analyses.

Hospital Admissions From Claims

Information about hospital admissions, provided to us by health system partners. Using inpatient claim counts, we estimate the percentage of new hospital admissions with a COVID-associated diagnosis code in a given location, on a given day.

This data is different from the death data available from USAFacts and JHU CSSE: deaths are reported by the date they occur, not the date they are reported by local health departments, and data is frequently reissued as additional death certificates from recent weeks are received and tabulated.
