COVID-19 Wolfram Data Repository Retrieval

It never updates for me properly. This is what I do:

ro = ResourceObject["Epidemic Data for Novel Coronavirus COVID-19"];
DeleteObject[ro];
ro = ResourceObject["Epidemic Data for Novel Coronavirus COVID-19"];

Just delete and re-download.

Wolfram basically just provides some minor convenience by re-formatting the data to a more Mathematica-compatible format. It may be a better idea to take the data from the source directly:

data = SemanticImport[
  "https://raw.githubusercontent.com/CSSEGISandData/COVID-19/master/csse_covid_19_data/csse_covid_19_time_series/time_series_19-covid-Confirmed.csv", 
  HeaderLines -> 1
]

data[All, {1, 2, 5 ;;}][
  All, {3 -> KeyMap[DateObject[{#, {"Month", "Day", "Year"}}, "Day"] &] /* TimeSeries}]

Use ResourceUpdate for this:

data = ResourceData[ResourceUpdate["Epidemic Data for Novel Coronavirus COVID-19"]];
