Johns Hopkins University in collaboration with ESRI and others has posted a coronavirus tracking dashboard here that includes an interactive map. The base map comes from a mix of sources including OpenStreetMap. If you click on the icon consisting of four squares in the upper right corner of the map, you get a list of basemap sources, and If you zoom in to a particular country, the source of the geodata automatically appears in the lower right corner of the map along with the other virus-related data sources. It is nice to know that OSM is helping in the effort to contain and reduce the impact of coronavirus.
