Details

This dataset supports both national and subnational data sources with national level data returned by default. National data is sourced from John Hopkins University and so we recommend using the JHU class included in this package. Subnational data is supported for a subset of countries which can be found after cleaning using the available_regions() method, see the examples for more details. These data sets are minimally cleaned data files hosted by the team at COVID19 Data Hub so please see their source repository for further details (https://github.com/covid19datahub/COVID19/#data-sources) If using for analysis checking the source for further details is strongly advised.
