If you want to do your own analytics on these data, here's one approach, which I'm using. Start your project as a vanilla Git repo, then add the JH repo as a submodule.

  git submodule add https://github.com/CSSEGISandData/COVID-19

Then you can do pulls to have the latest data.

  git submodule update --remote COVID-19

Have cron run that daily and your data are always fresh.
