Raw data on confirmed cases and deaths for all countries is sourced from the European Centre for Disease Prevention and Control (ECDC).

Our complete COVID-19 dataset is a collection of the COVID-19 data maintained by Our World in Data. It is updated daily and includes data on confirmed cases, deaths, and testing.

We have created a new description of all our data sources. You find it at our GitHub repository here. There you can download all of our data.
