Does WHO provide an API or do you scrape web site yourself? In any case the data doesn't seem to be updated in real time. I also developed a dashboard myself using Wolrdometer as data sources which is updated every 10 min: https://coronavirus.gg/

Also: https://gisanddata.maps.arcgis.com/apps/opsdashboard/index.h...

Country selector resets to top-5 every time you change graphs :(
