COVID-19 Wolfram Data Repository Retrieval

Question

I'm using this dataset to check out the data on new COVID-19 cases. But there are two issues:

1. Two days ago it was working great and it had data up to March 13; 1 day lag. Now when I run the cell in mathematica:

   ResourceObject["Epidemic Data for Novel Coronavirus COVID-19"]
   

   it doesn't update past March 13. So I cannot get the newer data by running the cell again.

2. On the data repo page it says it has data as recent as March 14. But I think the original data comes from Johns Hopkins University (link), which seems to have updated 14 hours ago (March 15).

So how can I 1. get the new data and, if I cannot expect the Wolfram data to update daily then 2. is it possible to import the JHU data directly and turn it into nice TimeSeries objects like they provide in the Wolfram data repo?

Answer 1

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}]

Answer 2

Use ResourceUpdate for this:

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