Hi,
That's a great idea; this has been brought up by a few folks, and a search around the internet should reveal several examples of Kibana dashboards mapping COVID-19.
Some Elastic employees have been tinkering with dashboards as well, though to my knowledge we haven't created any "official" Elastic dashboard for tracking the outbreak.
If you create one, I'd encourage you to drop a note here to share it!
Meanwhile some interesting ideas here about COVID-19 dashboards ::COVID-19 Maps and ELK
Cheers
Luke
