An open API for Epidemiological Data, from the Delphi research group.

Status

About

This is the home of Delphi's epidemiological data API. See our API documentation for details on the available data sets, APIs, and clients.

COVID-19 Notice

We are working on collecting several new data sources that may be useful for nowcasting and forecasting ILI during the COVID-19 pandemic. Each of these will make these available as soon as individually possible, through our covidcast endpoint.

For a list of many other data sources relevant to COVID-19, publicly available through external sites, we have compiled a simple spreadsheet.

Note: apart from the COVID-19-specific data sources described above, the rest of this repository was built to support modeling and forecasting efforts surrounding seasonal influenza (and dengue). All other data sources than those in our covidcast endpoint should be held to great scrutiny (if they are even to be considered at all in this pandemic period), since they were designed to serve as indicators of typical seasonal ILI (influenza-like illness), and certainly not pandemic ILI or CLI (covid-like illness).
