The covidcast package provides access to numerous COVID-19 data streams, updated daily, covering the United States of America. These include publicly reported cases and deaths data, along with data the Delphi research group collects or obtains from partners.
The COVIDcast API includes:
publicly reported COVID case and death data
insurance claims data reporting on COVID-related doctor's visits and hospitalizations, obtained from health partners
aggregate results from massive COVID symptom surveys conducted by Delphi
mobility data aggregated from SafeGraph
symptom search trends from Google
and numerous other important signals, most available daily at the county level.
Each data stream is identified by its data source and signal names. These are documented on the COVIDcast API website: https://cmu-delphi.github.io/delphi-epidata/api/covidcast_signals.html
Each data stream has a page giving detailed technical documentation on how the data is collected, how it is aggregated, and any limitations or known problems with the data.
We recommend browsing the vignettes, which includes numerous examples:
